The question of how to check the computer for viruses online is very popular among beginner users. Before you offer verification methods, I recommend to get acquainted with the following information about online checks for viruses : The main thing is that you should know - to complete all files on the computer somewhere on the site on the Internet will not work, because then you would need to download the entire contents of the PC or laptop to this site. But you can:
- Check for viruses individual programs and other files in full online by downloading them to special services.
- Download special antivirus utilities, which, although they are called "online scanners", but work on your computer, and from the Internet use an anti-virus database to check (which can also be downloaded to the computer). As a rule, they do not conflict with already installed antiviruses.
In this manual details the various methods of online checks for computer viruses from Windows 10, 8.1 and Windows 7 or individual programs and other files. I note that often the cause of certain problems with the work of the computer or the Internet is not viruses, but malicious programs that ordinary antiviruses "do not see". In this case, I recommend to try special means of removing malicious programs.

Online checking for viruses of individual programs and files
There are several popular online services that allow you to download a suspicious file and receive a report on whether it contains viruses or other threats.Virustotal
Virustotal - One of the most famous and popular services for online checking files for viruses. All that is required to check the program file (or another file, but not the RAR archive - such files are pre-uninstal) - it is to perform the following steps:
- Go to https://www.virustotal.com/
- Drag the file to check the mouse on the open site window, or click the "Choose File" button and specify the file on your computer.
- Wait for the file check for viruses.
- You can also check the address on the viruses on the Internet by inserting it on the URL tab.
Note: Recently, the Virustotal interface update and the Russian interface language from the main page disappeared. But, I assume the translation will appear.
Virustotal is notable for performing checks using several anti-virus "engines" immediately, that is, in the report you get a common picture compiled by various well-known and not very antiviruses. At the same time consider the following points:
- Single detection usually talk about false positive.
- Programs for remote access to the computer, utilities for configuring and optimizing PCs (twigs) often show a significant number of detection: in this case, you need to study the texts of the results. Usually they report that it is RiskWare - software with potentially dangerous capabilities (and any programs for remote control of a computer or deep change of Windows functioning can be attributed to such).
- In addition to the test results for well-known files, you will also see the community's opinion in the upper right corner (Community SCORE) and on the Community tab. You can also read it if you have doubts.
An additional feature is the official extension of the Virustotal for the browser, which allows you to check the files for viruses without downloading them to the computer.
Kaspersky Threat Intelligence Portal
Previously, Kaspersky service for online verification of files for viruses was called VirusDesk, now - Kaspersky Threat Intelligence Portal , Which's home page: https://opentip.kaspersky.com/ And the option in Russian has not yet appeared.
The essence of the use is the same as in the case of Virustotal:
- Either transfer the file with the mouse or load from the computer by clicking the "Browse" button, click the "Analyze" button.
- As a result, the service will show whether the file is pure from the point of view of Kaspersky (that the Clean file will report the inscription under the SHA-25 checksum for the downloaded file.
- Also on the main page of the service you can enter the hash (file checkline) or the site address and click the "Look Up" button for a quick check.
Online checking a program or file for viruses in Dr.Web
W. Dr.Web. There is also own online checkup files for viruses and other threats available at https://online.drweb.com/result2/
Use is perhaps easier than any other similar services: load the file into a single field in the center of the browser window, scan, we get a brief result in Russian.
Hybrid Analysis
The lack of two listed test methods is their limitations to the only anti-virus checking. Virustotal is deprived of this shortage, but if you are interested in even more powerful tools online checks for viruses, I recommend to get acquainted with Hybrid Analysis.
At first glance, the service is not much different, but during the check you can select a virtual machine on which your suspicious file will be launched and get very detailed and convenient for studying the analysis reports. Separate service instructions: Online viruses check in Hybrid Analysis.
Online scanner Nano Antivirus
On the official site Nano Antivirus. https://www.nanoav.ru/ In the "Services" section there is an online scanner for checking programs and other files for viruses.

Online scanners for checking a computer for viruses, do not conflict with installed antiviruses

- An online scanner for some time (depends on the speed of your Internet connection) will load the anti-virus database, and then check the computer for viruses and other threats.
