antivirus software :)

   Antivirus or anti-virus software is used to prevent, detect, and remove malware, including but not limited to computer viruses, computer worm, trojan horses, spyware and adware. Computer security, including protection from social engineering techniques, is commonly offered in products and services of antivirus software companies.

   In order to be an effective defense, your antivirus software needs to run in the background at all times, and should be kept updated so it recognizes new versions of malicious software.
