I had a similar but not identical problem, which was the product of one of the bastard variants of Cool Web Search. It may be worth your while to go to the Merijn website and download CWShredder.exe – if someone has the site bookmarked and can provide a link, I’d be grateful. This may be the cause of your problem, or it may be a completely different hijacker. But it only takes a minute or so to locate, download, and run it – if you can get to Google or another search engine, look for cwshredder.
Thanks for your support. Downloaded your suggestion and followed directions but to no avail.
When I click on my gold star on my bottom task bar which gives me all my fovorites including straight dope, the offensive red lettered blocker does NOT appear and everything runs smoothly. Could it be a malfunction of yahoo itself? :
