You would be amazed how many people I come across who have their computers infested by viruses. Many got a free trial of an anti-virus program with their new computer and think that they are protected even though they have never updated the virus signatures.
So what do anti-virus programs do? Well, if you compare them to protection you have at home, they work like this....
You plan to let someone in to your computer. The anti virus program checks them out to see that they really are who they say they are. It also checks that no sneaky criminal is getting in by hiding behind a genuine visitor. Once your guests are inside it makes sure that they don't get up to any mischief.
How do these 'visitors' get in? You invite them by looking at certain websites, downloading your email and opening it or by running software on your computer.
Virus writers are both clever and sneaky. They keep coming up with ways to get past your security and cause trouble. Anti-virus programs have to be able to recognise them, so the best are updated every day or even more frequently. There can still be problems, even with a good program. You may let in a virus on Monday, lets say, but because it is a new virus, your anti-virus may not be ready to protect you until later in the week. So you should arrange to do a full scan of your system at least once a week ON TOP OF the real time scanning that goes on throughout the day.
Please feel free to email me if you want some help or have a query on this topic.
If money is a factor in your not having an up to date anti virus program, there are a number of programs available for free. You can find one at this link http://free.grisoft.com/
