That is great news, the more folks leaving Windows, and going to Linux, the better. False positives with ClamAV can be a thing, there really isn't a real quality anti-virus app solution on Linux, that I really like.
The reason for this, ( I think ) is because over the past decades, Linux hasn't had issues with virus's or malware, because they weren't written for Linux, they were written to target Windows users, as that is where the market is.
Having said that, over the past 5 years, its becoming known that virus's are being made to target Linux users now, so its irresponsible to operate Linux, without an anti-virus solution. Still though, the chances of getting a virus are low.
I've gotten a virus or malware from installing Windows software in Wine before, but here's the beautiful thing, again, those virus's were coded for Windows users, and can't do anything to a Linux system in a Wine bottle.
Now, there used to be Eset nod32 or whatever it was called for the Linux desktop. However, by the time I learned of this, they had already discontinued their GUI desktop solution, due to low marketshare and usage, and thereby focused on their terminal only server solution.
But as it is, ClamAV is really the only solution that we have, but hey, at least its free! Have you looked into the prices that top shelf anti-virus APPs are costing people yearly? Its getting really insane now days. At least most apps on Linux are free, so there's that.
Like Gen-Z, both of them are glued to their mobile screens.
