Here it goes. I had been doing some video editing. I left my machine because it was taking a long time. When I came back avg virus program was on and said it had encountered a virus. I know for a fact it had not but something in one of the programs triggered some reaction because my avg wouldn't work properly. I had to shut it down. Then my pinnacle studio 8 shut down. Things weren't working properly and I had to restart. When I restarted my mouse it wouldn't work. I went to install it with my disc but everytime I put it in it went to hydravision and not my mouse drivers and software?? My usb on my dell flat panel don't appear to be working right now. I finally got my mouse to work but when I go into devices on the device page the choices keep on blinkingl. There are no yellow marks or anything. What does it sound like? Do you think I should reinstall avg? I think I may need to reinstall my ati all inwonder software and drivers. I may even need to reinstall pinnacle studio 8. Help
