Ransomware Protection allows detection of processes that attempt to encrypt user's files using known algorithm that defines processes as a security threat. Ransomware is one of these processes. When entering a computer such malicious programs block access to user data and then demand ransom for decryption. They are considered among the most common malicious programs and cause great annual losses both to companies and ordinary users. The most common way of getting infected are bulk emails containing malicious files or a link to malware.
According to Doctor Web statistics, probability of restoring files compromised by encryption ransomware is only 10%, that is why the most efficient way of fighting it is to prevent the infection. Recently the number of users that have suffered such infection has decreased. However, the number of Dr.Web technical support requests for decryption reaches 1000 every month.
