This is a help for everybody wanting to learn about computers. The most reliable and safe website I have found is at http://www.cnet.com.  . Before you download anything from cnet.com or any other website you want to make sure that the program is compatible to your computer, Windows xp, Windows vista, windows 7,or Windows 8.  Otherwise you may get the   infamous blue screen of death. What this means is that you loaded an incompatible program. So, let start by looking for a good Firewall.  Zonealarm is one that I recommend it handles inbound and outbound.

Maybe you would like to stop paying for an anti-virus and using a free one.  Before, you start to download that new anti-virus, you will have to remove the old one.  To do this if you have Windows XP, you want to go to all programs, find your anti-virus, click on program and click  uninstall.

For Windows Vista, and Windows 7, go to the start button, control panel, Programs and Features, click on the Anti-virus, that you want to remove and click Uninstall.

For Windows 8, move your mouse to the bottom left corner, Right click, click on Programs and Features,find the  Anti-Virus and uninstall it.

Once you uninstall the program then restart the computer. Now you can head on over to cnet.com Just click the link below:

There are also other free antivirus programs  including Avira  On making your choice  make sure to read the reviews, this will tell you what problems were found while it was being tested.  Be aware and be safe.
