Norton anti virus 2009 not scanning, vista 32 bit home edtiion

Hello everyone,

 

If anyone could give me some advice I would greatly appreciate it. I am sure I have a virus, so I started norton to do a scan. It comes up and starts to scan but the number of items scanned always stays at 0, and it stays like that for hours. I have the patch and have run live update. It has disabled ie, but i can use firefox sometimes, it also keeps my processor running above 50%. I have checked my startup programs and do not have anything odd there.

 

This is the error that ie gives me.
