There are a lot of free antivirus software with features that are almost comparable to their paid counterparts. Personally, I haven't shelled out any money for a paid antivirus software. I'm very cautious when I surf the net, and I think my free software does the job for me. But I'm not saying that paying for an antivirus software is stupid. Have you tried any paid antivirus software? Or are you like me who only uses a free software?
