Hacktool is a dialer that dials expensive toll numbers through the modem of your computer. These charges will be added to your telephone bill. The numbers dialed are pornographic in nature, and will possibly download additional pornographic material on your computer. It is also capable of placing malware on your PC, which can track your online activities like the searches you perform, and even personal information like credit card numbers and passwords. Hacktool will usually make your computer perform slowly, and also display pop-up ads to you. For complete security, Hacktool should be removed at once. It usually installs when you visit questionable websites, although it may be placed on your PC because of a weak security system. Remove all infections and malicious threats with Spyzooka.
