I think my ex-gf may have installed some kind of spyware on my pc. I gave her my apartment key one day while I was at work. She claims she never used it and was never there that day but when I got home and used my pc the DOS screen came up and asked "would you like to save system configuration changes" or something to that affect. When I went to the start button word pad was on the list which is something I've never used. When I opened wordpad the name of one of my encrypted files was on the recently saved list. Anyone have any idea what might have happened or what I can do to find out what if anything has been installed on my pc???
