I switched from XP to Mint 17 about a month ago, and Mint does seem like a great alternative (especially considering it's free). As I get more into everyday use, though, I wonder how secure Linux really is. With Windows, there are huge companies built around antivirus and general security applications. With LInux, ClamAV, which seems pretty lackluster, is the only option. The Linux crowd tends to rely on the "fact" that malware is mostly written for Windows. Be that as it may, it's only a matter of time before somebody decides to exploit that. I don't know anything about the programming involved in this question about security, but just want to throw the question out there to get your thoughts. Thanks! Edit: I meant to add that my Linux system is being used by my whole family, and they aren't as mindful of PC and online security as I am.
