Windows Computers are Now Protected by Bitdefender’s Free CryptoWall Immunizer
Bitdefender has an interesting piece of news for Windows users: its CryptoWall Immunizer is available for free protecting you against versions 1 and 2 of the file-encrypting malware.
File-encrypting ransomware was one of the toughest challenges in the antivirus industry in 2014. This family of file-encrypting viruses first appeared about six months ago but it has already wreaked havoc. More than $1 milion have been extorted and users who refused to pay ransom have paid dearly for their refusal.
“Ransomware is not only technologically challenging for both users and antimalware companies, but its success in extorting money is inspiring other cybercriminal groups to enter the ransomware business. The tool we are releasing blocks the encryption process even if the computer becomes infected.”, said Bitdefender Chief Security Strategist, Catalin Cosoi.
Just a quick reminder, back in 2013, the Cryptolocker attack alone succeeded in extorting more than $30 milion. Also, important database were destroyed, inflicting serious damage to companies.
The IT industry uses different encryption algorithms and because of this asymmetry, there is absolutely no chance that one recovers the files without the private decryption key. Apart from blocking these version of the file-encrypting malware, the program also stops other threats that use the same entrance point. CryptoWall Immunizer works by blocking all the folders that are in the %appdata% or %startup% folders.
The problem is that sometimes the program blocks other safe programs whose executables are in the same folders. To avoid this, press WIN+R and type %appdata% to see whether such programs are installed in the respective folders.
In order to launch the program, you need to click the Immunization button and wait a few seconds until you see the message “Protection Enabled” on the screen.
