Hi, Sadly I have been visiting some untoward sites and have picked up something udetectable by avg, wormguard, symantec online, adaware and tds. It usually starts when I am online but sometimes initiates offline. It involves the mouse left clicking rapidly. It will occur for about 30 secs and then go away for some time. It will click whichever button is selected on the desktop. eg if I have selected to open winamp on the taskbar/ destop, I will get about twenty instances of that software opening I dont really know what is going on. I also notice that pegasis my mail client will have a momentary lag in performance when writing a message. It seems to me to be like a sreen shot being taken. Love to find out what this mouse clicking is before I try a reformat again.
