What Can Be Done To Prevent Cryptolocker?
The Cryptolocker malware is not new, but has recently become more prevalent. It can be prevented by being cautious with emails attachments and do not open or interact with any suspicious documents sent to you in an email you weren’t expecting or do not recognise.
