ICQ and other IM programs are slightly dangerous if you download or allow anyone to send you items. Even a picture can be an iffy proposal. I suggest only one IM program for the PC since it's open source and well beat up for the security angles. Of course one can always override that, accept a download and let a pest in. Here it is -> http://gaim.sourceforge.net/
Best of luck finding your pests and it could be something simple like a broken keyboard.
