What is Malware?
Malware exists in several forms: including viruses, ransomware, worms, trojan horses, rootkits, keyloggers, dialers, spyware, adware, malicious browser helper objects, and rogue security software that either presents itself as your antivirus control, or disables your antivirus software. Malware has three potential objectives: destruction
of data, data collection and transmission, or nuisance and interruption.
Recently, the CryptoLocker Virus, a type of ransomware, has been in the news. This virus installs itself on your computer and encrypts your files so you can’t access them without the proper key. Then, a payment screen pops up, asking you to pay a ransom of $300 for the ‘key’ to decrypt your files! For more information about the CryptoLocker Virus, go to http://bit.ly/18at7Gg.
