In the past couple of days I have gotten a most unusual sort of hijacker. At first it hijacked my hompage to a site called "myexexex.com" (dont go there it's porn). I thought it was a variant of the master-search hijacker (which I had previously) so I took all the steps recommended to get rid of that particular hijacker. It stopped hijacking my homepage, but every once in a while as I surf, suddenly the page will go to one of a couple of porn sites all on its own (either myexexex or your-daily-pics). For example, I will click on a link, and right after the page appears it will redirect to a porn site. I have no idea how I got this, as I am fully patched, have high security settings and run a firewall! Adaware detects nothing, hijackthis shows no unusual processes... I have no idea what to do! Please help.
