Under the advice of ATOT, I finally downloaded spybot and scanned my PC throughly! After 4 hours of operation (boy! this software runs SLOW) finally it shows 20 spys and adwares as result...I thought "great! now I just have to clean it" so happily I clicked "clean" and guess what? MS Photo editor pops up with a message reads "Photo editor cannot find or open blah blah blah"......WTF!! Now tell me what to do!
