@Jocklad...
A good question... Ask 10 people, you will probably get 11 opinions...
If you watch the youtube video posted by vagnerafonso,
It appears that malware can impact Linux, but how often & what scenario created that situation in the demo..??
If you still run windows and share files across distros, you could vulnerable.
If you only run Linux, you could say "Well I'm O.K"...
BUT being a good citizen you don't want to pass anything on to a Windows user/friend from Linux do you..??
So, given it's a "almost" a "set it and forget" with ClamAV,
I'm tending to err on the side of caution and will probably use it.
