Web Pages Being Blocked, Possible Spyware/Adware or Trojan

Hi,

I've been having problems trying to view certain webpages through Internet Explorer and Mozilla Firefox, and the symptoms seem very similar to the About Blank problem, but it does not effect my home page.  I have tried the most common apps such  as Adaware, SpyBot, Spyware Blaster,CWShredder and other apps such as Adaware away which have had no effect.

I did try the free online scanner at www.spywareinfo.com which does say that I have the About Blank spyware on my PC.

If anyone can help me remove this annoying thing it would be great.  This is the 3rd time that I've had it, but previously I had backups to restore from, but not anymore. :-(

Here's a copy of the log from Hijackthis if it's of use :
