CryptoDefense is a ransomware program that targets computers running Windows operating systems. The virus restricts access to the data stored on your computer by encrypting it. To decrypt your files and get back the access to them, you will be asked to pay 500 USD in Bitcoins. It also says that you have 4 days to pay and if you don’t, you will have to pay double, that is 1000 USD. If you don’t pay for it at all, the program claims that you will lose all of your data.
CryptoDefense uses RSA-2048 encryption which is practically impossible to break as you need a private key to decrypt it. You should never ignore CryptoDefense as if it remains on your computer, it can easily compromise your system by giving access to it for remote computer hackers. If you don’t want to lose any data or experience other privacy related issues, you should always have backups of your files, so you could restore them anytime. There are no guarantees that you will sort everything out by paying for CryptoDefense.
CryptoDefense can be installed to computers if users click on various suspicious popups that offer getting updates for your programs or the ransomware can come bundled with other software. Make sure you always download all your programs from reliable sources. Also be more careful with what you are installing to your system and never accept any suspicious downloads. Update your security tools regularly to ensure the best protection of your computer.
