Definitions says it's already up to date?

Hey, I'm a novice, usually have someone work on my computer when anything goes wrong. But get tired of paying $250 every time he touches my PC. If I call to ask him, he'll say, I'll pick it up and let you know....

 

When I go to my Symantec Antivirus Live Update, and try to get the latest update, It states that it already has the latest updates. I know this cannot be correct. I have run the power erase, but finds nothing.

 

The guy who works on my computer installed the following: 

 

Avenge 1.5 MicroDefs2 Corp9

LiveUpdate

Symantec Antivirus Corporate Client NT

 

 

Program Versions

Program: 9.0.1. 1000

Scan Engine 101.3.0.93

 

Virus Definition File 

Version: 5/2/2011 Rev. 2

 

Is there something I can do to rectify this myself, install a newer version myself, etc.?
