It is surprising that many users do not bother with virus scanners until they have been infected. Actually many users do not even know that they have been infected and continue using their PCs without a virus scanner, blissfully unaware of the havoc these viruses are wreaking.
Viruses come in many forms and this is just a few of them in general. There is the destructive type which will harm or destroy files on a computer. There is the invasive type which steals your personal information (like credit card details, etc) and there is also the hidden type which uses your PC as a “cover” to commit attack on other computers connected to the internet or network you are on.
So you can see why it is important to be protected. When choosing a virus scanner you should look for one that scans “online”. This simply means that the scanner scans every file whenever it is accessed. This will give you a fair amount of protection. The next thing to look for is the addition of a firewall. This will let you set rules and control the incoming and outgoing connections to your computer.
Another important feature should be a virus database update feature. New viruses hit the internet on a daily and sometimes hourly basis, so it is important that your virus scanner database is up-to-date so that the scanner knows what to look for. Ideally the update service should happen automatically so that you don’t have to remember to update it.
Apart from this, price is a very important factor. Not all expensive virus scanners are great and not all free virus scanners are bad. So before you go and make your purchase, do a lot of research and figure out which virus scanner is the best for your needs. This will ensure you get the best deal and the best protection that you deserve.
