Antivirus, Antispyware, Antimalware, AntiRootkit, etc.
A lot of Windows users are resistant to admit they need any security software, but they are wrong.

It is very important to have at least one security software installed. If you cannot afford the premium price, worry not. Free solutions are available for your Windows computers.
