One of the solutions to prevent these ransomware viruses is to install Reimage Reimage Cleaner Intego. It is also practical in CryptoShield removal process.

Recently detected by ProofPoint security researcher Kafeine, the malware seems to impersonate well-known file-encrypting threats. The previous version preferred the outlook of CryptoWall[1], the current version sympathizes with the creators of Locky[2] as the ransom message is identical to the one employed by the menacing threat. No matter that CryptoShield seems to work in a similar manner, the threat uses two types of encryption techniques. As common for these types of threats, the ransomware encodes personal files with the AES-256 algorithm. However, it also uses ROT-13[3] encryptor which is based on a simple coding pattern. The latter does not cause any problems of deciphering. Naturally, the virus leaves its mark in the system – all of the data contains .cryptoshield file extension.  CryptoShield ransom noteCryptoShield combines several features of prevalent well-known ransomware viruses.

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.

    What is ROT-13 doing here? If files are encrypted with AES-256, there is no way you would recover them with this decrypter.
