Windows

Is avast! for Linux also able to detect Windows viruses? Meaning could I scan my C: with avast!?

Yes, the virus definitions are the same and the engine could detect Windows viruses.

That’s great news!

Thanks, Tech

You’re welcome.

Just to add some further info: Windows Viruses do not affect Linux OS’s.
The reason behind using an AV scanner in your Linux Distro is to stop the transmission of viruses to our friends who are running a Windows OS.

Therefore as Tech said:

Yes, the virus definitions are the same and the engine could detect Windows viruses.

Security compromise under Linux / Unix can be more a User fault rather than a Virus, in most cases.

Indeed, Abraxas. Thank you.
