Exterminate It! Antimalware


Known threats:700,085 Last Update:March 01, 12:55


I just wanted to thank you. My computer was frozen last night thanks to an online Easter card that was sent to me via the funcards site. I couldn't do anything but open windows.
I tried to open the exterminate it program that I purchased last year but the funcards site was blocking it, too!
I decided to purchase a new year of service (knowing my current one is going to expire sometime this month). It took two hours of searching, but exterminate it fixed my computer last night.
I have no idea how you all do it, but I would be lost without your service.
Thank you!!!
