just so i'm understanding this correctly. you have 3 anti-virus running at once? not good.
second. did your icons switch in any kind of order? like did they all go down 1, or right 1, or go "down" 1 alphabetically?

All my desktop icons have switched, is this a virus? - Yahoo! Answers
if this doesn't help, wait to see if any1 in here posts something. if they don't, and your problem isn't fixed by 1 of the suggestions here/in the link/or using ONE anti-virus doesn't help, then

good luck.
