We are busy writing a pdf download that you can down load directly from chephrenrepairs.com to act like a check list to keep your computer working properly. but whilst we are writing this we will give you a few hints right here from our blog...
There are a number of things you need to sort out, one of them is as you would expect your Software Firewall Wall, your Fire Wall should be switched on and you should look through the settings of it and ensure that it is switched on and that it is not going to stop working because your licence runs out next week. If you have no software fire wall buy one install it and get any updates that it needs. There are a lot of software firewalls available and if you need one and am a beginner with computing do not download a firewall, instead look in some computer magerzines or ring up a computer shop in yellow pages, be it on line or the paper version.

There are a number of software products that combine anti virus and a software fire wall in the same product, that is fine and if you buy one or have one, you do not need a second software firewall. Your software firewall is very important and if it is switched off or is simply missing, or it is set to allow everthing through it you are missing a really important trick, and running extreemly excessive risks.

Many Firewalls do have several modes of operation, and if you have a few moments you should see if your firewall can be put into training mode........... why because the fire wall will then ask you if certain programs should be allowed through, this is very usefull because it gives you a real opportunity to learn more how the fire wall works and to learn at the same time what programs are accessing the internet, this is very usefull....

I recommend that even if you have a router with a firewall inside it, and most do have that, that you do also have a software firewall as well.
