Cotgrave Computers

CryptoLocker is a ransomware trojan, when infected with this virus certain file types become encrypted (Pictures etc), your then offered to decrypt these files if you pay the ransom, CryptoLocker itself has been around for a few years and is not a new concept! There are other variants of this malware using the prefix Crypto, for example Cryptobit, CrypyoLocker can be easily removed however recovering infected files is not so easy so keep backing up your data as you should anyway. The best way is to get an external hard drive from online stores such as Amazon.

Gameover ZeuS (Zbot) is a virus that is commonly used to steal online banking information, email account logins, facebook etc, it can also infect you with other viruses such as CryptoLocker, again this has been around for many years and not something new.

A botnet is a network (Net) of infected computers (Bots) controlled by the virus to act together to infect other systems.
