U've been infected.

Go to: and search for malware bytes.

Download run it.

Also, in Internet Explorer, under internet option, then connection, Lan settings, make sure you have no proxy set.  have a look how here:

Good luck.
Have you checked the "host" file in C:\Windows\System32\Drivers\etc and/or "Restricted Sites" in Internet Explorer?
Open the "host" file with Notepad and check for entries of Anti-Virus websites. In "Restricted Sites", look for the same.
There are also a couple of anti malware programs that I use along with "Combofix". Try Malwarebytes and Super Anitspyware. Both are free.
Sounds like your computer is still infected.

I should have mentioned to remove any entries in the "host" file or "Restricted Sites". By Default, the only entry in the "host" file is the "loopback" address for your computer - i.e.   localhost

Google Hijackthis

Run it.

Post the log here.
If nothing is being detected then maybe restoring Internet Explorer to default settings might help.
For IE 8 in the "Advanced" tab; choose "Reset" and check the box to "Delete personal settings". Restart Internet Explorer.
