I'd use Spybot, Adware, Cwshredder and follow up with a scan with Housecall to eject all that they find.
All these free tools are found with http://www.google.com
If you can't eject the pests, be sure to post in the Security Forum since this is closer to your issue/topic.
I recently contracted a bunch shortcuts to my explorer favourites bar. Anything is listed from buying flowers to cheap software. I dont want this crap on my favourites bar, but deleting does not do the trick. After every re-start they appear again. I take this is some kind of software stored somewhere. Can someone tell me what to look for.
