Got a call from UTH (Urgent Tech Help) telling me I have a virus on my computer... was willing to take my credit card to expedite the solution (like I would give it to him).  Google the "company name" and you will find the scam documented all over the Net.  I have to admit though, it is fun leading these scammers on.  They get so angry when they find out you are an IT pro that doesn't fall for such silly scams.  :)
