There are many factors required to choose the best kind of anti virus software, driven by effectiveness, impact on your existing machine and lastly, cost.
Given the ever changing landscape of malicious code and virus attacks on personal and business users alike, a few pointers to selection criteria for anti virus products are listed below, which will hopefully help reduce the risks associated with poorly configured anitvirus products and high risk online activities such as downloading illegal music and watching streaming media from questionable sources.
The points to consider are as follows:
- Check the rating of the product with an organisation such as Virus Bulletin (http://www.virusbtn.com/vb100/index) prior to purchase
- Don’’t buy a multi year “value” license – the rankings of some products change as time goes by
- Make sure that the software uninstalls cleanly in the event that you need to change products
- Make sure that the antivirus scanning has the capability to run an off-line scan. By off line scan we mean where a system can be booted up using a dedicated anti-virus disk and scanned without the operating system being able to be compromised by a root kit or similar form of virus / malicious code vector
- Make sure that the product has a long support life – some free products are continually being updated and require installation of the current years version
- Make sure the product has a mechanism to have its virus definitions updated manually and automatically. there are instances that you may suspect a virus infection, but you are hindered by the fact that ouy cant connect to the internet to carry out automatic upgrades.
If you follow these basic guidelines when you think about upgrading your existing anti virus product, then you will be well on the way to selecting the right product.
In the event that you discover you have made an error of judgement, don’’t be afraid to replace the product. A virus / malware infection will always cost you more in time and money than the tens of pounds spent on changing a defective product.
