Checking your computer for viruses without an antivirus. Kaspersky AVP Tool – free scanner from Kaspersky Lab
The Virus Removal Tool utility is one of the most effective tools for detecting and eliminating almost any virus program. Its main advantage is that it does not require installation on a computer. Just download and run it, and then it will do everything itself.
This utility has a lot of advantages, including:
- The program is distributed on the Internet completely free of charge.
- The utility has a nice design and is very easy to use. With its help, even a beginner PC user will be able to conduct a full system check.
- Virus Removal Tool does not conflict with those installed on your computer, so you don’t have to disable them during the scan.
- The utility uses signature and heuristic analysis in its work, which allows it to detect new and unknown viruses.
- The program can treat infected files.
- If the infected computer cannot start in normal mode, you can run this utility in safe mode.
- After the program collects all the necessary information about the installed OS, it will create scripts with which you can perform treatment manually.
But in addition to a wide list of advantages, like any program, Virus Removal Tool has a number of disadvantages:
- The program works online, protecting the system, and scans and disinfects only on demand. After one-time use of the program, it is uninstalled.
- The utility cannot update databases, so before a new scan, you need to delete the old database and load a new one.
- Because The utility is free and does not contain any additional services. For example, the user will not be able to ask Kaspersky Lab a question if he suddenly encounters any difficulties. Answers to questions can only be obtained from other users on Kaspersky forums.
Performing a system check
The Virus Removal Tool utility can be downloaded from the official website using the link below. After downloading and unpacking the archive, you must agree to the license agreement and click the “Get Started” button. Now the antivirus utility is ready to work.
The program already contains recommended parameters for the first system scan. To start scanning, you just need to click “Run scan”. The utility will check all critical areas, and then you can scan the hard drive. To do this, click on the gear icon and check all the boxes in the “Scanning area” column. If there is a large amount of data on the computer, the scan may take quite a long time. In order not to monitor the long process, in the “Actions” menu you can select the “Treatment” and “Delete if treatment is impossible” checkboxes.
Please note that if unlicensed software is installed on the computer, the program can recognize them as a threat to the system, so it is recommended not to check the “Delete” box if there is unlicensed software on the PC. When all the settings are set, you can go to the “Automatic check” section and start the process. Upon completion of the scan, you will be able to view the monitoring results from the “Reports” section.
A proprietary utility from Kaspersky Lab Kaspersky AVP Tool is a free scanner that quickly and efficiently detects Trojans, viruses, Internet worms and thousands of other threats. They are then either deleted or moved to quarantine.
Kaspersky AVP Tool has a fairly simple appearance. Its installation on an infected computer takes place within a couple of minutes – even if we are talking about Windows Safe Mode. The search for malware is carried out using signature databases and has its own heuristic analyzer.
The latest version of Kaspersky AVP Tool, which you can download from the website, has significantly improved the user interface. The creators of the scanner simplified the installer and configured it to run from flash drives. The treatment of active infection, as well as the self-defense of the process itself, has also been improved. Don’t forget about the use of cloud technologies called Kaspersky Security Network.
Among the features of Kaspersky AVP Tool:
- A completely free antivirus utility to quickly scan your computer.
- The program has a simple appearance.
- Allows you to collect information about the system and makes the creation of treatment scripts completely interactive.
- Manual and automatic treatment of your PC from Trojans, viruses and worms.
Of course, the price for having a free scanner is that Kaspersky AVP Tool does not provide the user with real-time protection. It also does not include a module for automatically updating virus databases. This utility will not replace a regular antivirus. Therefore, we advise you to install a free antivirus, which you can download here, or purchase a paid one.
For a new PC scan (for example, in a week or in a month), the user will need to download this utility again with the latest antivirus databases. Kaspersky AVP Tool does not conflict with other antivirus programs, so it can be used as an additional means of protection.
- Letter. Please tell us on your website about, for example, Kaspersky Virus Removal Tool or Kaspersky Security Scan, I think they deserve attention. I just had a dispute with a friend, he tells me that the best anti-virus utility that works without installation on the computer is . I don’t argue, and you often mention it in your articles, it actually finds and neutralizes malware well, but I think the utilities from Kaspersky are no worse than the utilities from Dr.Web. Kaspersky Lab even has a utility called TDSSKiller.exe - it finds and neutralizes malware such as rootkits. There is an article on your website about, but not a word about the above-mentioned utilities. Or you think that they are not effective in fighting viruses. Max.
- Letter No. 2 I downloaded the utility from Kaspersky Kaspersky Security Scan, but it turns out that it does not remove viruses, but simply informs about threats and the security status of your computer. I don’t understand what the point is in using it then. No signature.
- Letter No. 3 Admin, help with advice. When scanning the computer for the presence of rootkits using the Kaspersky utility TDSSKiller, it was found suspicious object, medium danger – Service: sptd. The instructions for using the utility say: copy the suspicious object to quarantine and then send the files to Kaspersky Virus Lab or check for viruses on VirusTotal.com. In short, I copied a suspicious file to quarantine and wanted to check it on the VirusTotal.com website, but I can’t find the quarantine itself, there is no information about this anywhere in the program settings, the Kaspersky forum advised me to carefully read the instructions for using the TDSSKiller program, but there is no such information in the instructions either. No signature.

Kaspersky Virus Removal Tool
Let's start with the Kaspersky Virus Removal Tool utility, analyze all its settings and check our computer for viruses.
The language is Russian and click Download, then download the program installer to our computer and run it.
We agree to the license agreement and click Get started.
The free utility Kaspersky Virus Removal Tool can be launched in Automatic check, there is also a Manual Treatment mode.
Before you click Run scan, I advise you to go to the program settings. In option Check area, be sure to check My Documents, My Mail and most importantly Disk (C:). Why?
When scanning the infected computer, I did not select Disk (C:) in the settings and the Kaspersky Virus Removal Tool found only one virus in startup,
, but did not find the second malicious program - located in the Temp temporary files folder
. I had to rescan Drive (C:) separately, and only after rescanning was the virus found.
Security level can be left in the middle
Option Action, you can check the box - Prompt when detected.
If the Kaspersky Virus Removal Tool utility detects a virus program on you, it will inform you to Disinfect, (if possible) Delete (recommended) or Skip.
So, let's go, let's press Run scan
The first Trojan program was found after 8 minutes.
The second Trojan, as I already said, was found during a second scan, so do not forget to select drive (C:) for scanning in the program settings. The utility immediately offered to remove the second malicious program.
As for manual treatment. It takes place in three stages. Click Collecting information about the system,
The utility collects the information it needs, which is located in the file avptool_sysinfo.zip
Next, register on the Kaspersky Lab forum in the Anti-Virus thread, ask your question and attach the avptool_sysinfo.zip archive, you should definitely receive an answer, and sometimes specialists may suggest you run a script, which you need to copy into the Execute Script window and click Run Script.

At the end of the utility, the following proposal is received. If you press the button Install protection, we will immediately be taken to a page with paid antivirus solutions from Kaspersky Lab.
Free utility Kaspersky Security Scan
Let's move on to the second Kaspersky Security Scan utility, we will check the same infected computer with two viruses: in Startup and in the Temp temporary files folder.
The Kaspersky Security Scan utility does not remove viruses, but after scanning your computer it provides detailed information about the threats located in your operating system and where they were found, vulnerabilities and other problems. It all looks like this.
Let's go to the page again http://www.kaspersky.ru/virusscanner, select Kaspersky Security Scan and click Download.
Download and run the utility. Again I want to say that if Quick check you are not satisfied, then choose Full check. In my case, the situation with Quick Scan repeated itself; it found only one virus in Startup.
During a full scan, the utility found a second malware in temporary files
C:\Users\Username\AppData\Local\Temp
After a while
The free Kaspersky Security Scan utility will give you this report. Click on the arrow.
What is the state of the anti-virus program on your computer? I got a note because my anti-virus program was disabled at the time the utility was running.
If the utility finds malware, it will give you their location.
Rescue Disk Kaspersky Rescue Disk
The advantage of checking the operating system from a rescue boot disk over other utilities is that the malware found in the operating system is inoperative, one might say, simply lying on the hard drive.
Select Kaspersky Rescue Disk and click download.
Download the disk image in ISO format, burn it to a disc. Who doesn’t know how to burn an ISO image onto a blank CD or DVD, read our article
So, after we have burned the image onto a blank CD, we boot our computer from the Kaspersky Rescue Disk. Again, for those who don’t know how, read our article
In this window, to continue loading, you need to press any key on the keyboard.
We choose the language Russian, however, who needs which one.
We accept the conditions - press key 1.
Choose Graphic mode.
Wait for the disks to mount.
Here is the desktop of the Kaspersky Rescue Disk antivirus disk. Let's look at the main capabilities of the disk.
Click on Kaspersky Rescue Disk to open a settings window; there is nothing complicated to manage here. In the settings, we additionally mark drive C: for virus scanning, or if you want all drives, but the scan in this case will take a very long time. Click on the button Run check objects.
Kaspersky Rescue Disk has a registry editor, which you will agree is very convenient; by the way, earlier versions of the disk did not have it.
You can also use the File Manager if you need to move your files from one hard drive partition to another.
And using the built-in browser you can access the Internet.
TDSSKiller - protection against rootkits
Well, the turn has come to the TDSSKiller utility, which can help you detect and neutralize rootkits on your computer. A rootkit is a program for hiding the presence of a malicious program in an operating system, helping an attacker to manage a hacked Windows and hide traces of his malicious activities by hiding destructive processes and the rootkit itself.
You can download it on the official website of Kaspersky Lab; by the way, detailed instructions for using the utility are available at this link http://support.kaspersky.ru/5353?el=88446 Click Download the file TDSSKiller.exe
Download and launch.
If the program displays a window indicating that an update is available for download, click on Download update.
By default, the utility is configured optimally and there is no need to change anything. Click Start checking.
If after scanning the program displays the following window - Suspicious object, medium danger - Service: sptd, then this is not scary. Service: sptd is a service of the program - the Daemon tools disk drive emulator. You may ask - How can you determine whether it’s scary or not?
TDSSKiller can detect the following suspicious services or files:
Hidden service – a hidden key in the registry;
Blocked service– inaccessible key in the registry;
Hidden file – a hidden file on the disk is hidden when enumerated in the standard way;
Locked file- the file on the disk cannot be opened in the standard way;
Spoofed file- when reading, the file’s contents are not real;
Rootkit.Win32.BackBoot.gen - suspected infected MBR boot record.
For detailed analysis, Kaspersky Lab recommends copying detected objects to quarantine by selecting the Copy to quarantine action (the file will not be deleted!!!), then sending the files to Kaspersky Virus Lab or VirusTotal.com scanning.
Quarantine location is the root of the C:\TDSSKiller_Quarantine driveOpen the website VirusTotal.com, then click Select file
Open and Check
At one time, I established that this file is safe, but to be completely sure, our reader can send it to Kaspersky Virus Lab.

Kaspersky Virus Removal Tool is a free “light” version of the antivirus that fights the consequences, but does not prevent viruses from entering your system. As you know, it is easier to sell a product to a person if he has tried it and liked it. This is what many software companies do with their paid solutions. They give you a program to use for free for a month, and then ask you to buy the full version. This model has a slightly different principle: you are provided with a full-fledged antivirus, but which can only remove existing viruses from your computer. If you want complete real-time protection, we recommend purchasing the full package. Since our portal specializes in free software, we decided to download Kaspersky AVP Tool for free and see what it is like.
Possibilities:
- checking your computer for viruses;
- manually treating your computer.
Working principle:
Kaspersky AVP Tool Portable is essentially a portable program: when you run the installation file, it does not install the program on the computer's hard drive, but loads it into memory. If you exit the program, it will not remain on the computer, and you must run the installer again. When the program is launched, you can start automatically checking your computer. It will check system files for intrusion by foreign programs. Also in the “Manual Treatment” section, you can start collecting information about your computer’s software and send it for analysis to the “911 Anti-Virus Service”.
Pros:
- You can run it from a removable device and cure an infected computer.
Cons:
- takes up quite a lot of space;
- does not provide permanent protection.
In our opinion, this program can only be suitable for emergency treatment of an infected computer, but of course it is not suitable as a regular antivirus. If you need to cure a computer with viruses, you can download Kaspersky Virus Removal Tool for free on our website.
Instructions
Download Kaspersky Virus Removal Tool. If you do not yet have this program installed, go to the manufacturer’s website to download one of the versions of Kaspersky antivirus. To do this, enter http://www.kaspersky.ru/antivirus-removal-tool in the address bar. Select one of the versions and click the "Download" button. After this click, select the location to save the Kaspersky Virus Removal Tool and click the “Save” button. Then activate the antivirus by clicking the “Run” button. To fully install Kaspersky antivirus, you will need to wait from a few seconds to one minute.
Check any individual object. To do this, open the main window of the Kaspersky Virus Removal Tool program and click the “Scan” button, which is located at the bottom of this window. After that, drag the object you need into the area to check. This area should also be located in the main window of the Kaspersky anti-virus program. You can perform the same action in another way. To do this, open the file scan option and select the ones you need to scan them for viruses. Create a list of objects you want to scan and add them to the scan list. If you need to check the files completely, check the “Including subfolders” checkbox, and then “ok”. Also click “ok” in the “Checking objects” item. In a new window, the program will show you the verification process and its results.
Check the entire system at once if you think this is the best option. To do this, also run Kaspersky Virus Removal Tool.
Open the main window of the antivirus program, after which you will find a list of possible actions when working with Kaspersky antivirus. Select the “Check” item in the menu, and then click on the “Full scan” button. The antivirus will begin scanning your computer for malicious objects.
Useful advice
The antivirus scans files on the computer separately, so it is advisable to scan in this way.
Even if it seems that there are no viruses on the computer, this does not mean that the system is clean and free of malicious code. Most computer-harmful programs do not manifest themselves until certain conditions are met. Therefore, from time to time it is necessary to run a disk scan for viruses, even if at first glance it seems that there are none in the system.
Instructions
Download an antivirus program. There is a huge selection of anti-virus software, and therefore when choosing a particular utility, be guided by the goals and reviews of users, the frequency of updates and the number of viruses that are included in the database. The more frequent the updates, the more likely it is that the program is able to cope with the malware and it completely protects the system from the penetration of even the newest viruses.
Run the installation file. Follow the instructions that appear on the screen. After installation is complete, be sure to restart your computer. Make sure that the antivirus program starts immediately after the system boots, as this is a desirable setting, because many viruses can also be loaded during startup.
Go to the program window and find the settings item. Set the appropriate parameters related to the operation of the antivirus program to make your work as convenient as possible. Set the frequency of anti-virus database updates, enabled services, and notification output. After all the settings have been made, you can launch the “Scanning” mode.
Typically, antivirus utilities have two scanning modes. The first is called “Full Scan”, in which the program completely scans the system, system files and running programs, devices currently connected to the computer, as well as processes that are currently in RAM. A full scan takes a lot of time and significantly loads the system. There is a second option - “Partial Scan”, in which you can configure additional parameters and select the devices that the program will scan.
Video on the topic
Useful advice
A full scan should not be performed every day; it is enough to do it once a month. Perform a partial scan 1-2 times a week to completely protect your computer from viruses.
Any antivirus program automatically scans your computer from time to time for viruses and malware. But the fact is that they scan mainly system files on the disk where the operating system is installed, since they are the ones that are primarily infected with viruses. But sometimes only a full scan will make sure your PC is safe.
You will need
- - Computer with Windows OS;
- - antivirus program ESET NOD32 Antivirus 4.
Instructions
Next, we will consider the process of a complete computer using the example of the antivirus program ESET NOD32 Antivirus 4. You can download this software on the official ESET website. The free period of its use is one month.
Launch the program. In its main menu, select “PC Scan”, then from the list of suggested options - “Custom Scan”. In the next window, check the following parameters. Set the scan profile to "Deep Scan". In the “Scan Objects” window, check the box next to absolutely all available objects, including RAM and virtual drives (if your system has them).
If you just want to scan your computer without deleting infected files, then at the bottom of the window, check the box next to the “Without cleaning” line. If the checkbox is not cleared, all detected malicious objects will be automatically deleted. You can also select the level of maximum computer cleaning. To do this, click “Settings” at the bottom of the window, then in the window that appears, move the slider to the “Thorough cleaning” position and click OK.
Now after completing all the settings, click on “Scan”. The process of scanning your computer will begin. Its time depends on the power of the PC, the capacity and fullness of your hard drive. In any case, the process will take a lot of time. Do not load the computer with other operations during this time.
Once the scan is complete, you will be able to view the report. If you checked the box next to the “No cleaning” line and the program detected viruses, then you can view their list in the program window after the scan is completed. In the same window, you can delete infected objects or place them in quarantine. From quarantine, you can restore the file at any time. If among the infected files there is nothing you need, then it is best to simply delete them.
