I tired using Avast with Mint, as I'd put it on my Vista laptop and my brothers' and dad's. I read that it's not really worth bothering with AV software with Linux, so I wasn't too bothered when the following happened. After I'd downloaded all the latest Avast database updates I did a scan and it said that, basically all the files were infected! i.e. that it listed how many files were checked and then listed the same number of files were infected. It's pretty unlikely isn't it? I'm not seeing problems you could attriibute to that sort of infection. Just Avast not working well with Mint, at a guess; it's a very inferior version for Linux anyway. What do you think?
The other thing, I think probably I haven't done enough for the Firewall yet. I've turned it on, but am I _supposed_ to add 'rules', and if so, can you direct me as to how this is done, or link an idiot-proof tutorial etc. I've never had to bother with Windows,it does it all for you.
I only use Firefox and sometimes Limewire (with which I'm perfectly able to recognise virus files).
