Virus Found but NAV2009 Cannot even Detech while Kaspersky Can Detect

Photos.exe

IRC-Worm.Win32.AutoIt.a

and a few more with funny name and externsion which I can put here for now as I have manually removed them but they will definitely come back again after i rebooted.

 

And the supoort wants to charge me for helping me remove the virus which NAV2009 is not able to do.

 

Is this fair?
