AVG is a good security software that I’ve been using for my Windows machines. It has a free version that you can download at its website. Paid version is around $35 per year. Today, AVG announces that it launches version 9.0, though this new version is only available for paid users. The free version will get upgrade to version 9.0 later this month.
When comparing AVG against other security software, I found out that AVG was less resource intensive. It gets better, AVG is promising that with version 9.0 and depending on the system configuration, the anti-virus scanning process has up to 50% less resource intensive than its previous version which means the scanning process can be done faster. I found this fact is true as I have tested AVG 9.0. Fresh installation or newly update of AVG 9.0, it will ask you to allow it to scan for trusted files on your computer, and if you allow this function to process, the next time you scan your computer for virus, the trusted files on your computer won’t have to be scanned again, and this is how AVG 9.0′s scan process is faster than its previous versions. Of course you can reconfigure AVG to scan every file on your computer, though this will be slower.
Just like any other good security software, AVG has features that allow you to prevent spams from accessing your email programs, prevent you from being tricked to access malicious websites, detect and remove malware, detect and remove rootkits, and protect you from Identity Theft. The free version has less features than the paid version. For some people, the free version is more than good enough, but for others like me, I prefer extra features that may come in handy, and so the paid version is the way to go.
AVG has a firewall that allows you to configure to allow certain trusted applications to access your network and to block unknown applications and protocols. AVG’s firewall allows you to create profiles for different networks that you have access to. For examples, you can configure the firewall to be stricter when you using Starbucks’s network and less strict when using a network at home. Another cool feature that AVG has is by default AVG configures to watch out for viruses and worms that spread from the use of instant messengers belong to Yahoo, Microsoft, and AOL, and others.
