Spyware and computer virus terms (1/2)
This guide is part one of a two part glossary designed to help you understand what our computer repair technicians are talking about when they report to you that you have a particular type of virus or spyware.
Adware virus
Software designed to add advertisements to websites you view. Some times these viruses run programs to generate random advertisements within your operating system.
Boot virus
A virus that damages the master boot record of a hard drive. These viruses can be recognised by the fact that they computer will not boot. If you have a boot virus it is best to get an expert to repair your computer. DIY attempts may result in data loss requiring expert data recovery services. In extreme cases data recovery may no longer be an option.
Botnet
A network of computers that have been hijacked by a computer virus. The virus uses the hijacked computers to break into or damage a target computer system. Indications of your computer being hijacked by a Botnet include decreased performance and random network activity. To remove a computer from a Botnet you must remove the virus infecting the computer.
Firewall
A piece of hardware or software designed to keep nasty and dangerous software out of your computer and/or network. See our page on firewalls.

On-demand virus scanner
An on demand virus scanner will read through files as requested. Our computer repair technicians recommend at the absolute least running an on-demand scan once a week. Compare with real time scanner. As above, the intent of most virus scanners is to remove viruses not simply detect them.
