Everyone (hopefully) understands the importance of having antivirus software installed on each of their computers and servers. However, I’m continually amazed at just how many businesses & individuals want to spend as little as possible (ideally nothing) on their antivirus software. This is just plain wrong.
I’m also appalled at how many of our competitor IT companies want to sell antivirus software purely based on the margin they can make or how easily they can install the antivirus software across multiple machines.
The unfortunate truth is that there is no antivirus product on the market that will catch 100% of all malware (viruses, worms, Trojans, spyware, adware, phising, etc.). However, some antivirus products are significantly better than others. In my opinion, you should not be buying your antivirus software based on the lowest price that you can get away with, but instead, you should be protecting your business with the best antivirus software available.
So what is the best antivirus software?
Each quarter several independent groups test the various antivirus programs in order to determine how effective they are. Personally, we believe that AV-Comparatives’ tests (www.av-comparatives.org) are the most comprehensive and reliable. They conduct various different types of test, to determine how effective the programs are at detecting all types of malicious programs (malware) under different circumstances. For some years, they have been testing 16 programs; this rose to 20 in February 2010.
So which one comes out on top? We’ll, it actually depends on how you interpret the results. On the “Stay Safe on the Internet” website (www.staysafeontheinternet.co.uk) (put together by my colleague David, with a little help from yours truly) we use the following five factors in order to compare antivirus programs:
- Protection, the ability of the program to recognise and block/remove viruses and other dangerous programs from your computer.
- Speed of the antivirus program, i.e. how much it affects the performance of the computer.
- False alarms, also known as false positives, occur when an antivirus program wrongly identifies a harmless program or file as being malicious.
- Ease of use is also a very important consideration.
- Telephone support from the manufacturer of the antivirus program is invaluable.
Taking these factors into consideration we have determined that the following are currently the top five antivirus programs:
- Kaspersky Internet Security – offers the best protection.
- ESET NOD32 – very light, fast, trouble-free antivirus program with outstanding technical support.
- F-Secure – good all round, with 24/7 telephone support.
- Avira – recommended for experts only, due to the lack of phone support (unless you can speak German).
- Gdata - same as Avira.

At Solutions Shared, we tend to recommend ESET for business clients and either ESET or Kaspersky for home users, depending on their Internet surfing habits and the age of their PC (ESET is better than Kaspersky on older PCs).
Maximum Protection
Unfortunately simply having antivirus software will not guarantee that you will never be infected with some form of malware. Instead you need to apply a multifaceted approach, which includes all of following:
1) Installation of all operating system (Windows, Mac OS, etc) security updates as soon as they are released.
2) Installation of the latest security updates for application programs, including, but not limited to, Microsoft Office, Adobe Reader, Adobe Flash, Apple QuickTime, Real Player.
3) Ideally removing local administrator permissions from all staff – if you don’t have admin rights most “drive-by” malware installations will fail when you open the infected file or click the dodgy web link.
4) Educate your staff. A small amount of training goes a long way. Staff should be provided with some basic education on how to be savvy email and Internet users.
