Top 10 free PC programs everyone should have

There are millions of free and open source projects available, many of them better than any commercially available product. Below is a short listing of what we think is the best out there, broken down into ten categories.

Antivirus and malware protection

Most PC users realize that they need protection on their computer or may have an installed antivirus program from their computer manufacturer. What most don’t realize is that there are free programs that are just as good and in some cases better than the commercial products. Below are our recommendations
antivirus program: Avast! or AVG
Malware and Spyware protection: Malwarebytes

Backup solutions

There are dozens of free and commercially available backup programs for computers. Unfortunately many of those backups are stored locally, meaning if your house were to catch fire, get robbed, or if you lost your backup discs all your data would be lost. This is why when dealing with important data we suggest users use online backup services.
Online backup solution: Mozy or Dropbox

Although Microsoft Internet Explorer comes pre-installed on Windows computers. There are several excellent free alternatives that everyone should try. These free alternatives can often be faster, have more options, and in many cases be more secure than Internet Explorer.
