Malware is a malicious piece of software designed to damage your PC or spy on your computer activities without you knowing about it. What follows is a list of common types of Malware and their descriptions.

Adware.
Adware is one of the less harmful forms of Malware which will display a popup advertisement on your computer when your not expecting it.

Symptoms of an Infected Computer.

One of the first signs of infection is a marked reduction in speed and performance of your PC. Sometimes even appearing to pause or hang. Another is that windows will behave erratically and unstable. You may experience popup windows when you don't expect. If you have a good antivirus program it should inform you of the presence of Malware and offer to remove it for you.

How Does my Computer Get Infected.
Email.
If you receive any email from unknown or unexpected senders make sure that you scan it before opening it with your antivirus software and if you have any doubts don't open it.

Websites.
Browsing some websites that are suspect can lead to infection because the Malware can be hidden as code in the web page itself.

Peer to Peer File Sharing Software.

Popup Messages.
It is possible to use what is known as IP Popups to infect your computer. IP Popups can be sent strait to your computers IP address bypassing popup blockers.

Networks.
Computers on a network can all get infected from one computer as data is passed from computer to computer. That is why all computers must be protected with a firewall and Antivirus software.

Making Your Computer Immune to Malware.

Use Internet Securities Software
The most effective way to protect your computer is with good quality Antivirus and Antispyware from a reputable company like Norton or McAfee.

Which ever one you use just make sure that you keep it regularly updated and remember to renew your yearly subscription. Remember, out of date antivirus software is completely useless.

Always use a Firewall.
Windows XP and Vista both have a firewall built in and you should have them switched on. If you have a good internet securities program this will have a Firewall included which should be used in favour of the Microsoft version.

Use Windows Update.
Update regularly to ensure you have all the latest critical security updates. Microsoft are releasing patches all the time to close up security holes in their operating systems.

Curing your Infected Computer.
All Antivirus and Internet securities software will be equipped to remove Malware easily. If you set them up to do so they will remove Malware automatically and then inform you once the offender has been dealt with.

A Word Of Advice.
Visiting illegal or immoral websites will increase your likely hood of becoming infected considerably as these sites tend to be set up and frequented by people who have no scruples and will think nothing of infecting your computer along with many others.
