I had a lot of ad/spyware downloaded just recently and have been able to remove everything with Spybot and Adware but I have still have a pop-up from pegasusstudio.com coming up.  It interrupts what I am doing online and then begins to install adware, TOOLBARS, you name it.  I have not been able to find any info on it.  

Any suggestions?  Anyone run across this before?

Thanks!SET Adaware SE or Spybot S&D to run at START up.I have actually run both of those at startup.  And it seems to remove it, however it sleeps somewhere and returns after a few times online.  (dial-up) Those are two piecees of software I use religiously and have worked for all ELSE.  This seems to be a parasite or something similar.

Thanks for your reply.I suggest you scan for viruses/trojans if you have not yet done so.

You may wish to install a popup blocker or use Adaware Adwatch. (ASSUMING you have got a registered version) to detect and block registry changes that are caused by Spyware.

Spy Sweeper is also a very good program to remove spyware.

Using an alternate browser such as Mozilla Firefox is a very good idea as well.http://www.rcmillar.netfirms.com/subpages/Links.htm#Spyware_
