Suddenly I've been getting this message. I googled it and tried some of their suggestions. I clean the cookies and history daily in FireFox as well as IE (even thought I hardly use it). Defrag & disk clean up weekly, use 3 spyware programs and Trend Micro daily. Security set at medium. It has been in the 90's here and with everyones air going, could that be a factor? Any suggestions? Thanks.
