CryptoDefense Virus is a dangerous ransomware infection that intends to steal as much money as possible from terrified computer users. According various news reports, CryptoDefense Virus first appeared in February 2014 and ever since then it has infected over 20,000 computers in more than 100 countries. As a result, the criminals behind this infection managed to collect over $34,000 in ransom fees. If you got infected with CryptoDefense Virus as well, do not even think of paying the ransom, because that paying will not make CryptoDefense Virus go away. You need to remove CryptoDefense Virus from your computer and then invest in a reliable antimalware tool that will secure your system from similar infections.
Due to its behavior, CryptoDefense Virus may seem to be related to CryptoLocker Virus, which is also known as an obnoxious ransomware application. However, there seems to be a stark difference between the two programs. CryptoLocker Virus locks you out of your computer and encrypts your files. Unless you obtain a private key after having paid the ransom, you cannot restore your files (especially if you have not set a system restore point before that). However, the situation with CryptoDefense Virus is slightly different.
When CryptoDefense Virus enters your computer and blocks you from accessing your files, this infection also demands you to pay $500 or €500 in bitcoins so that you would be able to decrypt your files. Technically, the private key which allows you to decrypt the files should be stored in the infection’s servers, but CryptoDefense Virus makes a mistake by leaving the private key on the infected computer. Therefore, after you have removed CryptoDefense Virus from the system, you can actually decrypt all the affected files yourself.
It is necessary to delete CryptoDefense Virus as soon as possible and then avoid similar infections in the future. To prevent ransomware from getting into your system, you need to refrain from opening spam email and social engineering messages. For example, CryptoDefense Virus is distributed via spam email attachments. Spam email messages that deliver CryptoDefense Virus are often sent from multiple locations and multiple IP addresses, so it is rather hard to determine the culprit behind this scam.
Once the infection takes place, you see a pop-up message that informs you that your files were encrypted:
Luckily, CryptoDefense Virus does not block you from accessing your desktop or the Internet. Therefore, you can download a reliable antimalware tool and terminate the infection automatically without any difficulties. Scanning the system with a powerful antimalware scanner will also help you to determine whether you have other infections on your PC.
