Anybody know about viruses?

So, i have managed to get some shitty virus on my laptop. Basically whenever I login I am getting a fake 'This webpage cannot be displayed' screen. It is bigger than a normal IE screen and you can't close it. Even task manager closes when I try to open it.

I tried doing a malware bytes scan both in safe mode and while logged in as a guest. It found some shit but that didn't solve the problem. I also did a full scan with security essentials and that also found and removed some shit but that hasn't helped either.

Sorry for posting it in here but could do with some help.

You'd better go on some antivirus forum and post your "Hijack This" scan log. They will tell you what to do - you'll probably need to delete it manually with "Avenger" (was it called like that?) or "Killbox" or similar program.

You could try and restore your computer back to a point a few weeks prior...and see if that does the trick?
