I had a virus on my computer, so I came here and you guys fixed it for me (thanks, again). Well now I can't burn CD's and the drive won't read any CD that I put in it. Also, when I plug my camera in the USB port it won't pick up my camera, but it will pick up my MP3 player, and it also will not detect my camera's memory card when I plug it into the memory card slot. This all happened only after the virus was removed from my computer. Is it fixable or permanent?
