Here is my encounter with viruses:

"Back when I was administering multiple office networks across the region, I have seen some viruses such as "Netsky" attacking the computer networks and they come in by the thousands (20,000 in a night to be precise!).

Fortunately, I had an anti-virus program that was blocking these virus onslaught from entering into the Computer Data Centre which holds the company critical operations and data storage. The unsung hero (The anti-virus) did it's job well and not a single virus came through the company network. Unfortunately, the server that runs the anti-virus had a hardware failure due to the extremely high traffic of cleaning these viruses.

I had to immediately get ready a standby server to take over the anti-virus job and later installed a clustered anti-virus solution for high availability. This meant an anti-virus software is the absolutely the first protection that a computer cannot do without".

So how to get protection and are there FREE Anti-Virus?

The ANSWER is yes. One of the popular Anti-Virus is AVG Free Edition Anti-Virus.

(2) Another form of Internet threat is Spyware.

Spyware programs are able to retrieve various types of personal information and can also by itself install additional software, pointing your web to other web sites that may have viruses. Furthermore, multiple spywares can cause your computer to slow down as it takes up your CPU, Memory and Disk space. Your network performance may also suffer as spyware redirect unwanted network traffic.

Traditionally an Anti-Virus is adequate to protect a PC but now it is essential to also include Anti-spyware program to counter this threat. Anti-spyware programs are to monitor your PC for spyware while giving you a peace of mind while going about your on-line activity.

There are also FREE and popular Anti-Spyware programs such as Spybot Search and Destroy and Lavasoft Adware Personal.

(3) Trojans

These are computer programs that can hide themselves behind an innocent looking e-mail attachment (e.g. a tempting computer game). Once the attachment is executed, the trojan will install itself into the computer and it can now start doing damage to your computer.

Some trojans has spyware, which is software that keeps track of Internet usage statistics and it will send these information back to the creator.

Most anti-virus comes with trojan removal. However, nowadays it is better to equip your PC with a personal firewall. It will help you to block unwanted applications/virus from trying to penetrate your PC.
