How to Get rid of CryptoDefense?

Help! My new computer is infected by CryptoDefense. My Avast has detected and removed it, but CryptoDefense kept coming back when I scan my computer. Why can’t my anti-virus remove this nasty ? Should I remove this virus manually or change another anti-virus? Any help will appreciate.


CryptoDefense is identified as a ransomware virus which is harmful to your machine. CryptoDefense virus is created by cyber hackers to swindle money. Normally, it is packed with freeware installation packages and spam e-mails. Once you accidentally execute those infected files, CryptoDefense virus will slide into your system, and then quickly begin its malicious activities. To begin with, it locks your screen and prevents you from accessing your system. Besides, in order to deceive you, it displays a fake notification on your screen saying that your PC is locked because it is involved in some illegal activities.

Facing such notifications, you must bear in mind that DON’T believe them at any time, because they are all tricks designed by criminals for the purpose of gathering money. On the other hand, CryptoDefense virus will not disappear automatically. What it does is hiding deeply in your system and continuing its unauthorized activities, like exploiting system vulnerabilities, installing other malware and stealing your confidential information. You need to know that the longer CryptoDefense virus stays in your computer, the more problems it generates. If you connive with its spiteful action, your system will break down sooner or later. All in all, when your PC is locked by CryptoDefense virus, you must try your best to remove it ASAP.
