It is always important to keep your computer well maintained. One thing the inexperienced computer users forget to do is keep their antivirus program up to date. Antivirus programs are not install and forget programs. They need to be kept up to date! Check the instructions on how to have the program automatically update itself. If it doesn’t have this feature make sure you do a manual update regularly (i.e. at least once a week, more often when there are rumours of viruses going around). Even if the program is set to update automatically it wouldn’t hurt to do a manual update every day or more often when the word is out that a virus is going around.
