Hello, I have many different problems suddenly such as windows closing all the time, pop ups, Office keeps trying to start or install on it's own, curser moves while typing and hearing ads on pop ups that I can't see. I upgraded to AVG 8 and Adaware 2008 as I read on here. I shows some Trojan virus and JS/downloader.agent. I had the programs remove them but am still having the same problems. I don't know that much about computers as my brother worked with them for the Air Force until his death last year. He seemed to know everything and could talk me through all of my problems. I'm hoping to avoid having to pay to have this fixed. Thanks so much for your help!
