I'm using AVG Internet Security on Windows XP Pro.
I've got a little advisory screen for it which says:
Security components and status overview
Anti-Virus - Active
Anti-Spyware - Active
Anti-Spam - Active
Firewall - Active
LinkScanner - Active
Resident Shield - Active
E-Mail Scanner - Active
Update Manager - Active
License - Active
Online Shield - Active
Anti-Rootkit - Active
System Tools - Active
PC Analyzer - Active
Identity Protection - Active
So basically, just at one glance I can see everything is actually working and (theoretically) how well protected I am.
Thinks...I am probably being conned by this stuff just like millions of other Internet users. However, it looks good, is easy to manage and seems to work quite well and fast too.
Whenever I use Google this AVG stuff tells me which are the safe sites and which are Verisign registered sites on all of the Google answers. So that's nice.
Now I happen to know that any Anti-Virus system is not going to be 100% successful. However, it is best to have one and also one that you are happy to use. This seems to fit the bill for my simple mind.
The AVG version is 10.0.1191 and is '2011'
Here's a link to a page which tells you what all the above stuff means:
