Although not tangible, antivirus comes in many different shapes and sizes, literally. The layout of the software can vary depending on which brand and which distribution you purchase. Subsequently there are two decisions you need to make when you buy antivirus. Three if you include your budget within the decision process.

The first thing to consider is ‘do you really need antivirus software’. Some computers don’t require protection, such as apple macs and linux based operating systems. Secondly, you should consider the brand you should purchase. Usually one would think that comparing antivirus software is like comparing eggs with eggs; they are the same. But this is not the case. Many users have different opinions on antivirus software.

Ultimately the decision is up to you. Normally people tend to choose the application with the biggest market share, such as McAfee or Symantec. However, this isn’t a good idea with so many better but lesser known products available.

You might want to visit some sites that offer reviews on antivirus products. Some retailers allow the purchaser to return and write a review on the product they purchased. If you use this method you will most likely read a range of honest reviews from both novice and power users.

The next and probably best method is to is to simply trial a selection of products prior to purchase.Most antivirus products are available for a 30 day trial prior to purchase. This enables you to take a test trial and ensure the product is suitable for you and your computer before you part with your hard earned money.

Ultimately, because software can be easily uninstalled and replaced, you are rarely forced to stick with any provider for any means. Antivirus internet security software is no exception. So go ahead, trial some software and purchase what’s right for you. If you change your mind, you will only be tied in for the remainder of the licence before you are able to swap for a different brand.
