How to protect yourself from Cryptolocker and other ransomware

Cryptolocker is a nasty threat sneaking around the internet masquerading as a pdf file. This type of virus is known as ransomware because it targets files and then locks them up until you pay the demanded ‘ransom’. Typically, the ‘virus’ will enter your system disguised as an innocent file attachment from a major delivery service offering tracking information or confirming money transfer. Once you have clicked to access the file, the virus will begin to search your machine for files with common extensions such as .doc, .xls, .pdf etc, encrypt those files, then contact the user to demand payment. Anti-virus and malware tools will remove it, but files that have been infected will remain encrypted unless a payment is made, so it’s essential to prevent infection. The following is a guide to some of the ways you can protect your systems.
