AVG7 missing from Msconfig, therefore 'start-up' at BOOT-UP

My computer has restored to an early point because it wasn't connecting to
the Server..but now, i have noticed AVG7 is not in the Boot-up sequence,
and it used to have, like, 10 entries in msconfig.exe , but now is not there
...NOTHING
When i try and RUN AVG7 i get the error message 'could not initialise AVG
anti-virus kernel interface' ??
Please gimme some advice so i can get this vital App running at Start-up
again... Thanks - Morph
System - 333mhz Intel Celeron, winME ..
The only things i run at start-up(msconfig) = messenger,firewall,DSLMON, I
Just want all the AVG7 entries back, and it isn't allowing me to return to
an even earlier System Restore Point, but i aint that bothered cos i used to
have problems on the comp, back then...
Cheers Guys - Morph
