I've noticed lately (as I'm sure some of you others have) that some of
these rogue antivirus/antispyware installations are setting up a proxy
server entry in Internet Explorer which blocks or redirects internet
traffic. I don't remember how I first stumbled on to it but it is one of
the first things I check now. Malwarebytes and SuperAntispyware are my
first tools to use and so far (as of today) neither of them detect or
repair that setting.
