Everytime I surf the internet, I constantly receive an error message titled "Server Busy" saying "this action cannot be completed because the other program is busy. Choose 'switch to' to activate the busy program and correct the problem". Then after a delay the pop ups begin, and they all seem to originate from the same place -Ad.oinadserver.com or Ad.yieldmanager. I have the McAfee virus protection program as well as a newly installed spyware program called Spy Doctor, but nothing seems to be able to detect this unwanted program. All they do is remove cookies and files, but the program is still there. How can I get rid of this? I've been dealing with it for a year now and i don't think i can take it anymore. Please help.
