Apparently Visual Bee is a nasty piece of Malware which embeds itself into your system and needs to be removed by way of a malware-removal tool.
There's a very recent thread over at Bleeping Computer regarding a few people who've had this problem. From what I can tell from having read through the thread, a couple of people had success with a program called "AdwCleaner.exe" - which seemed to have removed all traces of Visual Bee from their systems. (Although they still needed to manually reset their homepages)
If I were you, I would have a look at the thread because it's only a few weeks old, and perhaps you could jump in to get help from one of the Malware-Removal Experts over at Bleeping:
"VB or Visual Bee Malicious Tool Bar - How to Remove Safely"
Hope this helps -- and please do report back and let us know how you make out - because that information could prove to be very helpful to others here who may experience the same problem at some future date.
