How to check your computer for viruses online?

check your computer for viruses online Hello! Today's article will be devoted to antivirus …

I think many people understand that the presence of an antivirus does not provide one hundred percent protection against all misfortunes and hardships, so it will not be superfluous to sometimes check its reliability using third-party programs. And for those who do not have an antivirus, it is even more necessary to scan “unfamiliar” files, and the system as a whole! For a quick system check, it is convenient to use small antivirus programs, in which the virus database itself is located on the server (and not on your computer), and on the local computer you only run the scanner (approximately takes several megabytes).

Let's take a closer look at how to check your computer for viruses online (by the way, let's first look at Russian antiviruses).

Online antivirus

3. By the way, before checking, I recommend disabling anti-viruses, closing all resource-intensive applications: games, watching movies, etc. Also disable programs that load the Internet channel (torrent client, cancel file downloads, etc.).

Conclusions:

With a connection speed of 50 Mbps, my laptop with OS Windows 8 was tested in ~ 10 minutes. No viruses or foreign objects were found (it means that the antivirus was installed for a reason). An ordinary home computer with Windows 7 was scanned a little longer (most likely due to network load) – 1 object was neutralized. By the way, after rechecking with other antiviruses, there were no more suspicious objects. Overall, the F-Secure Online Scanner makes a very positive impression.

Conclusions:

ESET Online Scanner checks the system very thoroughly. If the first program in this article checked the system in 10 minutes, ESET Online Scanner checked it for about 40 minutes. And this despite the fact that some objects were excluded from scanning in the settings …

Also, after the check, the program provides you with a report on the work done and automatically deletes itself (i.e. after checking and cleaning the system from viruses, there will be no files left on your PC from the antivirus itself). Conveniently!

conclusions

What is the advantage of online verification?

1. Fast and convenient. We downloaded the file 2-3 Mb, launched it and checked the system. No updates, settings, keys, etc.

2. Does not hang constantly in the computer memory and does not load the processor.

3. Can be used in conjunction with a regular antivirus (ie get 2 antiviruses on one PC).

Minuses.

1. Does not protect constantly in real time. Those. you must remember not to run downloaded files immediately; run only after antivirus check.

2. You need high-speed Internet access. There are no problems for residents of large cities, but for the rest …

3. Not as effective scan as a full-fledged antivirus, there are not so many options: parental control, firewall, whitelisting, on-demand (scheduled) scan, etc.
