Hello,
I have a problem with viruses. Some developers boast around me about not using antivirus software. Is it possible to manually remove viruses in the system32 folder? Please enlighten me on this issue. Additionally, if I have an infected removable drive, at what point does the virus spread to the computer: when I open the USB drive or when I connect it directly to the central unit?
Thank you for your help.

Hello,
First of all, there are several types of viruses.
Some infect the programs you use. This type of virus is almost impossible to remove manually without affecting the infected program.
However, this kind of virus has almost disappeared from the Windows world.
The most common viruses are simple programs that launch at the startup of your Windows; they launch multiple copies in memory to relaunch themselves if you were to remove one.
In such cases, it is quite simple to manually get rid of the virus (you must nonetheless identify the name of the program it carries). You will need to restart your Windows in safe mode (press F8 at startup): in this mode, Windows does not launch any unnecessary programs. Therefore, the virus will be disabled. You will then have all the time you need to remove the malicious programs.
To find the programs that launch at startup of your Windows, if you are not a fan of the registry, use the MSCONFIG tool, for example.
I am only giving you the main points; it's up to you to look for the details you are missing. This topic is vast.
Regarding your question about infected USB keys, the virus will not propagate automatically: you will need to run (by double-clicking, for example) the program containing the virus (and the PC must not be using an antivirus that would detect it).
There is only one case in which the virus could spread without user intervention: the USB key in question would need to emulate a CD drive and the virus would need to launch via Windows' autorun feature (only a few models of USB keys can do this). Additionally, the user must not have disabled the autorun feature and must have chosen that when inserting a CD into the drive, the default action is to launch the “Autorum” program.
Therefore, there is a low risk of contamination just by plugging in a key, unless the person who did this did it intentionally.
Good luck!

I caught a virus that causes my PC to automatically deactivate as soon as I turn it on.
Can I find out how to disable it without formatting?
Thank you
And I still haven't managed to eradicate it. Indeed, it contaminates any other drive that is connected to the initially infected PC with the infected USB stick, turning all documents into shortcuts!
