My computer allows access to only some sites. I can not go to Spybot, McAfee, Yahoo, nor Avast!, but I can go to Apple Support and
Microsoft Support. Frequently, I get the message "server unexpectedly dropped the connection". What is causing this? I have
researched "redirect virus" and followed their advice, but so far nothing has worked.
reset your network card settings whether you use Eth cable or WIFi
check if all is set to default and no proxy servers are set.
Most likely your computer got infected. Download antivirus on any other computer and install it on the affected machine.
