Exterminate It! Antimalware


Known threats:700,086 Last Update:March 16, 12:51


Just want to let you know this is a great product. We bought it but it didn't get rid of the CID popups. We let you know and within 2 days we had a fix. Now we are CID free. My husband says this is the best money we've spent on a software product in recent years. We had been trying for 2 years (on and off) to get rid of these annoying CID popups and now we are CID free. Highly recommend Exterminate it. My husband says and I quote I am a believer!
