Renew and Update Your Antivirus Software Today

by Kwan H Lo


New computer viruses are unleashed every day.  Renew and update your antivirus software today.  This is the only way to protect your PC and stop the spread of these malicious programs.


PC users are facing new computer viruses every day.  Computer viruses not only affect home PCs, they clog up internet traffic and disrupt the business of big corporations, causing billion dollars worth of damage each year.  To protect the computer and stop the spread of these malicious programs on the internet, consumers should renew their antivirus program and update it weekly.


The number of computer viruses is increasing at a shocking rate.  In 2003, 7 new viruses were unleashed each day.  In 2004, more than 10,000 new viruses and their variants were identified.  These computer viruses not only affect home PCs but also invade the network of corporate computers. 


Computer virus is a collective term, which includes viruses, worms and Trojan horses.  These malicious programs attack the computer in different ways.  Some cause damage to the boot sector, hardware, software or data files.  Some create security leaks in the system.  Others may use the computer to spread spam e-mails. 


Viruses, worms and Trojan horses also spread by different means. Viruses are usually transferred from one computer to another by sharing infected files or e-mail attachments.  Worms replicate and spread by e-mail programs.  Trojan horses are often downloaded and run by computer users who do not know the true nature of these programs.


Good antivirus programs detect and remove viruses, worms and Trojan horses.  Although there are many new antivirus programs available these days, consumers should remain vigilant.  Beware of all the free scans and free downloads from unknown software publishers.  Some claim to be antivirus software but in fact, they add adware to the computer. 


Consumers are advised to buy only from reputable software publishers such as Symantec, McAfee, Trend Micro, etc.  They should also renew the license annually and update the software weekly.  This ensures that they are using the most updated detection database for full virus protection.
