Anti Virus on the Home Computer

In this day and age having a computer with out Anti Virus is just crazy, even if you don’t go on the Internet. There are billions of viruses out there and millions being released every day; you hear about the ones on the news and think it does not happen very often but it’s happening every second of every day.

Viruses are not the only problem out there; there are bigger problems, Malware and Botnets. Malware is software that installs on your computer, with out your knowledge and can do a number of things but mostly takes note of what you are doing. Some can be completely harmless but some forms of Malware can take note of user names and passwords and send back to its makers for them to do with what they want. Image what they could do with all your banking information, scary isn’t it and believe me they are out there.

Botnets is another problem roaming round the internet at the moment, Botnets again it’s another program that gets installed on your computer with out your knowledge, normally from some dodgy website you looked at by accident where it’s down loads in the back ground. What Botnets do once on your pc, is sit there waiting for a certain day/time or order from the Botnets master to then do what ever they want to do, they now have full control of your computer. They can silently send email to millions on behalf of your email account without your knowledge. Make you out to be a spammer. They can join forces with other infected computers and work as a team to bring down web servers, company systems, what ever the Botnets master tells them to do. Scary is the word.

The good news is most antivirus will combat these, BUT you must keep them up to date and I would recommend doing that daily. The software will do this for you automatically if told to. Having anti virus software installed but not up dating is as useful as not having any installed.

Now let’s say you have a computer that is not on the internet (this is very rare these days) and you have to move some files onto it. You can do this one of 2 ways copy them onto a portable device (portable hard drive, DVD, CD, USB memory stick) and transfer them that way or a cable between the both. The problem with both these ways is you have just opened up for virus to get in. They could be on your portable device or on the computer you are connecting to and as soon as they see a network connection come up they hop on over, happens all the time. Bulk of virus are made to look for active network connections so as they can infect (spread) to as many as possible.

So again having anti virus software (and there are great free versions out there) that update every day is a must in this day and age I cannot stress this enough, whether you are on the internet or not.
