Dear Exterminate It,
I just wanted to take a moment to say thank you.
Your response and the update has fixed my problem.
I have spent several weeks fiddling around trying to resolve it, and could not and my previous Anti-Virus program could find it but not fix it.


Sincerely yours,
Bountiful, Utah
