Sorry to bother, but I need a help. Today I turned on my computer and a lot of things happened at the same time: my free antivirus (avast!) was getting a error and couldn't update Windows gave me an error when I tried to start Malwarebytes my Internet Explorer was lagged Firefox gave me a lot of "firefox crash reporter" windows my Windows style (blue bars) apparently was "merging" with the classic style of the windows on your own and my pc suddenly restarted these problems occurred with me 2 times and all these things were at the same time. I use Window XP Professional (ServicePack3) and when I could open my Malwarebytes I've done a complete scan and there weren't any malwares found on my pc. What might be? Again, sorry to bother.
