Hurray for Windows! That was my pro windows based computers cheer! Now don't everyone get all uptight about the Mac vs. Windows debate, I am not trying to start one and please don't you.
I had many virus and Trojan warnings with the past few visits to the OB. I use Google.ca extensively, browsing with IE8 and use Shaw Secure a security suite provided free by my ISP. The software is actually developed by F-Secure and licensed to Shaw.
Anyway, I cleared my browsing history, temporary internet files and cookies and all is fine now. No further issues.
Maybe that will help some.
