And free antivirus utilities and online scanners will help us with this.

The most important thing to note is that such utilities can only scan the PC for threats and remove them, they do not treat the computer, keep this in mind.

Before starting to analyze the topic, I would like to say that such programs only complement the main antivirus, but cannot replace it in any way. Therefore, I recommend installing full-fledged security software. Here are some of them from the last year.

Checking for viruses with free software

Microsoft Safety Scanner

Microsoft has created special utility to check the computer. It can download from office site. Please note that it is valid for 10 days!

Why so fast? As indicated on the official website, this is due to the fact that the entire process is carried out in the cloud, and the technology itself consists of identifying threats active at the time of scanning.

ESET Online Scanner

Another way to scan a PC or netbook without downloading an additional antivirus program. It is completely free for ordinary users. To scan, you will need to go to official site.


If you are using Internet Explorer, then the analysis will be performed without downloading additional files. If you use other browsers to access the Internet, then you will need to download a small file and run it.

Perhaps its main disadvantage is that each file will have to be downloaded separately, which is not convenient in all cases.

To improve the usability of online scanner Doctor Web, you can put all questionable documents in one archive, then send this archive in its entirety, at a time, for verification. But here there is a nuance, the volume of one archive should not exceed 10 MB, it is also necessary to understand that the download speed will directly depend on your Internet connection. Therefore, if you have a rather weak Internet, then downloading even such small files can take a long time.

Kaspersky online

Check important files for viruses and other threats, you can use free scanner from Kaspersky. It works online, without installation on a computer. In fact, this is a kind of analogue of Doctor Web, discussed earlier.



Kaspersky is distinguished by its support for downloading larger files up to 50 MB, which is very convenient. Also supports loading of all types of data, including archives. It works fast enough, for example, as a test, I decided to download a 36 MB archive, as a result, it was checked in a minute. Unfortunately, he does not deal with computer treatment, you will have to remove viruses yourself. Despite this, I definitely recommend it.

All disassembled programs perform only a few functions - detection and removal. They can't fix your computer. Therefore I recommend using full-fledged antiviruses, which will not only protect Windows from malware, but in most cases will be able to cure infected files.
