Your mileage may vary...Editing the registry is dangerous for neophytes and other newbies, etc, etc, etc. also download HIJACKTHIS.EXE and run it. It will show you all the nasty critters that are taking over Internet Exploder. Download Firefox.exe from mozilla.org and stop using Internet Exploder until you have a GOOD antivirus/popup blocker/adware remover installed
