lukexj, hello & to BC Forums! Glad to have you abroad!
The main thing that one would need a virus scanner on a Linux computer for, would be for scanning emails & other files that would be sent to Windows computers.
With that in mind, there's a free alternative called ClamAV, which is included with the OS. All you need to do is open the Terminal & copy/pate the below command in, which scans & cleans any threats found.
clamscan --remove=yes -i -r ~/
Hope this at least gives you one option to use.
As far as WINE goes, I don't want it on my Linux installs, the risks outweighs the benefits & WINE still has a way to go to be considered as a 'stable' emulator of Windows. A virtual machine is a better option, where the user has control over folder sharing.
Should you have further concerns or questions, always feel free to ask, there's no 'dumb' Linux questions around here.
