Much like organic viruses found in the real world, computer viruses, which are malicious programs, are just as crafty and can greatly damage your computer system, starting from slowing it down considerably to making it crash. Protecting your computer from malicious attacks is therefore of vital importance and even more so if you use the Internet on a regular basis.
Although you may religiously follow the golden rule of not downloading anything from strange websites or opening unknown attachments, there is always a chance of viruses sneaking into your system without you being aware of it. Also, with the increased incidence of flash memory drives being used as portable devices for storing and sharing data, the chances of a virus infection become even more pronounced. A virus present in your friend’s flash drive can easily be transferred to your computer when you plug it in. Thus there arises a need for anti virus software that will monitor your system on a regular basis, checking for virus attacks.
Some of the well-known commercial anti virus software include the ESET Nod32 Antivirus 4, the Norton Antivirus 2009, Kaspersky Anti-virus 2009, Panda Antivirus Pro 2009, AVG and the BitDefender Antivirus 2009 to name a few. Ideally, anti virus programs should come with the ability to detect a wide range of viruses and the manufacturing company should come up with regular updates. Getting updates on a regular basis is an extremely important factor as new viruses are created on a daily basis.
Now the ESET Nod32 Antivirus 4 is quite a well-rated commercial anti virus software that is fast and light while protecting against a host of malware. One of the highlights of this anti virus program is the use of its ThreatSense technology which comes is very handy as it can help ward off attacks from even new viruses.
Norton Antivirus 2009 is another commercial anti virus software that is widely used and protects your computer from a wide range of viruses, worms, rootkits and other infective agents. You can also get “rapid pulse” updates after every five to fifteen minutes. However, the flipside to using Norton is that you would have to pay for any technical support that you may require.
The Kasperky Anti-virus 2009, which is a little more expensive than other anti virus programs, is quite a force to reckon with when it comes to virus protection. The software is fast and easy to use while detecting viruses, both known and unknown present even in user applications. It also has built-in system restoration capabilities along with automatic updates.
The Panda Antivirus Pro 2009 is another solid anti virus program that has an “ultrafast scan engine” which along with viruses, also detects and removes rootkits. The BitDefender Antivirus 2009 is another impressive anti virus program which uses minimal computer resources while protecting your system from malware with 96% accuracy. AVG Antivirus is another reputed antivirus and antispyware program which has real-time virus protection and also has a free edition for home use.
