I have been on and of visiting sites that may give you a virus or malware i.e pirate sites etc and purposely without a virus program. Silly i know. I use avast when i do. I have done this for trial periods and yet I have not had any malware or a virus of any kind. I sometimes wonder if these progs are needed. I always have image file tucked away for quick recovery. Is it that easy to get a virus nowdays?
