Viruses, Spyware and Trojans (collectively: Malware) can cause buffering as well as permanently damage your computer software and hardware.
You should scan your computer with a quality Antivirus/Spyware program regularly. We recommend scanning your computer at least once each week.
Malware can, among other things, connect to the internet without your knowledge and download files to your computer, act as a proxy service for others (eats up bandwidth), and can make your sensitive personal data insecure. Having an active Antivirus/Spyware program running on your computer will help to ensure that only you are using your computer, that your information is secure, and your programs and hardware are safe.
