Need protection for your PC but don't want to spend anything? Read on...
Unfortunately, we live in a world where it's nearly impossible to connect to other computers and visit websites without picking up nasties that can affect our own computer.
It doesn't matter if you're using Windows, Mac OS, Linux, Android or any other modern operating system; you can guarantee that some little oik out there has developed a bit of code that will vandalise your setup and create untold havoc.
Thankfully, we have anti-virus programs to help combat and prevent such nasties from entering our system, or if they do, they can quickly be quarantined and dealt with.

However, there are many that are free to use and are just as good at protecting you as their paid-for relations. The problem, though, is knowing which one to choose.
