Since Tuesday or so, nothing on my laptop will update--AVG Free 8.5, Malaware, or Windows automatic updates. The error message is always along the lines of "Update failed, couldn't connect to server". I haven't made any changes to anything, I was able today to successfully get a partial Windows update by running it with the Windows firewall disabled. AVG and Malaware still won't. I ran the Windows scanner and it found a Trojan:win32/seekwel.A virus and claims to have deleted it, as well as fixing some registry errors, but when I ran it it again today, it found the trojan again. I don't know that this is the problem, I'm able to open any website I want, just as always, though a bit slower than usual. My browser is Firefox, and the OS is XP. Any help?
