This is going to sound paranoid and whacko, but I'll ask anyhow. Spyware - is it possible to get some type on your computer that copies files while you're offline, stores the copies somewhere on your computer, then sends the stuff "home" next time you're back online?
The reason I ask is as follows. I have Adobe CS4, Acrobat and Photoshop are the only two elements installed that I know. Lately, every time I go to close a pdf file, it takes forever. The little red "close" box top right with the cross on it goes dark brown, then it's like the computer temporarily freezes with respect to that pdf - it just sits there - then it closes after about 3-30 seconds (varies).
One loony thought that occurred to me was that it took so long because it was saving a copy of itself somewhere. I used to scan personal stuff that nowadays would be good for ID theft so I'm wondering now whether I should have?
So, loony question or not, I ask it.
