Detection

• Virus detection can be tricky. Without anti-virus software you must pay close attention to your system. Other times, an infection can be glaringly obvious. If your system is behaving oddly by running very slowly and advertisements are popping up, or you internet browser is malfunctioning, then there is a good chance your computer is infected.
  
  

Anti-Virus Software

• Avira, Avast, Trend Micro and WebSense are a few of the free anti-virus software solutions available. Install and configure your anti-virus software to scan the computer frequently. When a virus is detected the software will alert you and present options to help prevent, limit or reverse the damage the virus may have caused.
  
  

Recovery

• The most fail-safe methods to restore your computer to its previous state are to backup your system externally and use the built-in recovery features that come with most operating systems.
