If you want to ensure the real-time protection of your computer system against the latest virtual threats, then you will need a strong anti-virus.

So, why not AVG Antivirus Professional 2012? It's easy to work with, fast, and it rarely misses its target.

Once installed, the trial version for AVG shows you two windows and a few options.

In the main window you can see whether the anti-virus, LinkScanner, e-mail protection, anti-rootkit, PC analyzer and identity protection are active (in overview mode), while in the left window you can opt for a scan, update, or configuration of scan options.

The anti-virus component of AVG protects your computer system from viruses, worms, spyware and Trojans, while LinkScanner blocks web-based attacks and network traffic when you're online.

E-mail protection guarantees the integrity of incoming and outbound e-mails (including filtering of spam), while the PC analyzer does a complete check on your computer in order to find any problems regarding registry errors, junk files, fragmentation errors, and broken shortcuts.

At the scanning configuration you can set to scan the whole system or only a specific part, anti-rootkit, or schedule scans.

In addition, you can install apps for AVG, which work in the same principle as the apps for browsers. For example, AVG PC Tuneup speed up the computer, while AVG Mobilation is an anti-virus system for mobile phones.

We did a full tuneup on our computer systems, and AVG indeed found some errors that other anti-virus software missed. The entire scanning process ran smoothly but took a lot of time, and memory resources were consumed to an average.

You can never say for certain if one anti-virus software is good for you while another is completely weak. In this case, the best thing you can do is to try out AVG Antivirus Professional 2012 and see how your computer likes it.
