Hello guys, if you are thinking that you can encrypt your drives using BitLocker facility given by Windows and you can avoid getting attacked by a ransomware infection then you are wrong. If you use that encryption process, it means you can protect your personal files and data from being access without your permission. In most of the cases it might protect your from viruses that is looking to steal or delete your files but Ransomware is a whole other game. If your system get hit by a Ransomware infection, it does not care whether your have encrypted your drives or not, it will encrypt all your files and demand for the ransom money in return for the decryption key.
Simply there are two type of encryption methods are at play here. The first one is drive level encryption process which the standard feature provided by Microsoft that can help you keep your files private. It is good when someone else is trying to access your files or steal your data or if your system is stolen then your data will be protected with type of encryption methods.
The second one is file level encryption which is used by hackers for creating Ransomware malware. If this infection anyhow manages to get into your machine, it can encrypt all your files. If your drives are encrypted then it will still lock your data. In many cases we have found the dual encryption of the safe files in that same computer. Just assume that if your system is infected a ransomware infection and all your files are locked, at the same time if some another ransomware attack your system, then it will re-encrypt your files and both of them demand ransom money for the decryption key.
So it is quite clear that you can avoid ransomware attack by encrypting your drive or even your files. There is no way that encrypting a Hard Drive prevent Ransomware attack but you can protect your files by taking regular backups on any external hard drive. You can also create backup of your data store at different cloud drives for safe keeping. There are many cloud drives that offers up to 100 GB free space to store your files and backups which can be quite useful in case if your system ever get infected by a ransomware virus.
