I know this question is looking like an easy question or not a question at all but it's not really easy question. I'm not related to security and anti-viruses and just don't trust every provided anti-virus.
So first question is a real question - Is it OK (safe) to not use anti-virus at all. I know how to use firewall, usually I use only trusted connections and surfing trusted sites. My chances to get virus is really low. Even I've got a bit outdated PC and don't want to pay the performance for it. I can do monthly scans without having one installed - is it OK to be safe ?
If not can you recommend a good free antivirus solution?
