Webroot identifying problem on twenty ten theme

Hi,

I hope someone can help.

I have webroot anti virus on my computer. Everytime I load my blog or dashboard or do something it tells me that the site is suspicious for spam, scans and other nasties. It is the basic twenty ten theme and being a newbie, I am not up to anything.

I have deletde all pluins hopfully to return to basics but webroot still says it is suspicious. AVG and Norton do not pick up anything. What worries me is that everyone who has webroot will see those messages.

Please tell me somebody has had this problem and knows how to fix it I would be most grateful.

Many thanks, Gordon.
