User question
Hello.
Tell me, how can I install 2 antiviruses on my computer at once? It's just that Avast was standing not so long ago, and it did not find viruses, I deleted it, installed Nod - it immediately detected 3 viruses (apparently because of them the PC was slowing down).
Now I think that Nod cannot see all viruses either, and it would be good to double-check it ...
Good day!
In general, I want to warn you right away that installing 2 classic antiviruses on one Windows and organizing their parallel operation is hardly possible ...
The fact is that even at the installation stage, the antivirus will check if there are any third-party security applications that can cause a conflict during its operation (if any, it will give you an error and offer you to remove the installed antivirus first).
Even if you manage to install 2 antiviruses even by resorting to "tricky" methods, you will most likely get a very unstable system with frequent freezes, errors, blue screens, etc. 👀
But there is still a way out ... In this article I will show you how you can organize the scan of files and the system by several anti-virus products at once. Perhaps many users will find something interesting for themselves in the proposed methods ...

Cross scan of the computer with different antiviruses. How?
Option number 1: classic antivirus + Online version + special. anti-malware utilities
The most convenient and effective protection option is to use, in addition to the classic antivirus (with regularly updated databases), special software to neutralize malware (we are talking about 👉 IObit Malware Fighter, Malwarebytes Anti-Malware, Norman Malware Cleaner, AdwCleaner, etc.) ).
Such programs are able to work in parallel with your antivirus and significantly improve security. Note that they "see" those threats that a regular antivirus is unable to recognize (like, for example, the same adware for browsers).
👉 Remark!
The best software 👉 for combating malware (software works well at the same time as classic antivirus).

Besides, now there are quite a few antivirus products that can fully scan your system for viruses, and at the same time, they do not need to be installed.
Those. the scheme is something like this: you download a file, run it, the antivirus scans the PC and removes the threats it finds. And, actually, that's it! For the next check in a month (for example), you will need to download the antivirus file again.
Interestingly, such antivirus programs can run in parallel with your installed antivirus. Those. you can double-check its reliability without removing or disabling it. Conveniently!?

Option number 2: install several versions of Windows on the HDD, and each has its own antivirus
Another fairly popular option is to install several versions of Windows on a PC at once (this is often required not only for security, but also for compatibility, to run various programs). And in each version of Windows you can install your own antivirus.
Thus, when loading one Windows (for example, Windows 10 as in the screenshot below) - you can check your computer with one antivirus (Avast), and boot into another (Windows 7) - use Panda.

2 antiviruses on one PC (on different Windows)
I will add that in addition to the classic antivirus, you can install an anti-malware tool on each Windows + use your own online scanner (that is, use the first version of this article).

👉 Note!
When you have 2 (or more) versions of Windows installed, when you turn on your computer / laptop, you will see a list of installed operating systems and a proposal to choose which one to download.
Those. everything is quite simple (an example is shown in the screenshot below). You may have different software installed on each OS.

Option number 3: check suspicious files for special. resources at once by several antiviruses
In some cases, it is required to check not the entire system, but some file (2-3 ...) for safety. Moreover, it is desirable to have several antiviruses at once. And for this it is not at all necessary to install them on your PC ...
The network now has specialized resources to which you can upload a file, and it will be checked immediately by the most famous antivirus products. Very convenient, fast and reliable!

👉 VirusTotal
//www.virustotal.com/ru/
One of the most famous free resources for checking a URL or a regular file with dozens of antiviruses at once: AVAST, AVG, AhnLab, Baidu, BitDefender and many others. Note that there is a limitation: the maximum file size should not exceed 128 MB.

True, this method has, nevertheless, a drawback. Not all files and not always can be sent to a third-party service for their verification. Still, there is confidential information, valuable documents, etc.

Option number 4: use LiveCD-disks, flash drives
Nowadays, special bootable disks / flash drives with antivirus software are also quite popular (they are called 👉 LiveCDs).
Those. by connecting such a flash drive to USB (for example), you turn on the PC and boot from this flash drive (this can be done even if you have disabled Windows, or in general, the hard drive is disconnected).
Having booted from it, you will see the most common desktop with shortcuts for starting an anti-virus scan - i.e. the system will hardly differ from the usual Windows.
The only thing is that Windows needs to be installed on the HDD, and this system starts immediately from a USB flash drive (without installation).
👉 Of course, LiveCD flash drive / disk must be prepared and burned in a special way. How this is done, this article will tell you.

That's all for now ...

Good luck!
