One of the most powerful antivirus solutions that you will ever have the pleasure of using comes from Avast!.

Avast! Internet Security is a very effective software that protects your computer system against viruses, spyware, and spam.

We liked that fact that, during installation, Avast! created a system restore point without even asking us to confirm it.

The interface in Avast! Internet Security  is very pleasant and easy to use, for both novices and advanced users.

Here you can view the current status of your computer - firewall, real-time shields, auto updates, virus definitions version, program version, and expiration date.

There's also the option of switching to silent mode, and that means that Avast! will display various messages without automatically causing you to exit the fullscreen of a game you may be playing.

Scanning can be performed either quickly or thoroughly. You can either scan the whole system, just a portion of it, or removable media.

It takes a while to complete (in full mode), but scanning is very thorough. And yes, during this time, CPU and memory are moderately used (which is always an added bonus). Too bad the firewall function is not very strong.

Boot-Time Scan is a special feature of Avast! that scans the operating system right before startup, making sure to clean any infected files (it doesn't even take long), while Scan Logs displays a history of all completed scans that were either scheduled or not.

Avast! Internet Security is a pretty complex program, so you will most likely love its many features because they solely focus on protecting your computer. Combine it with a backup and recovery system, and you have the perfect recipe for system protection!
