First:
THIS MAY BE AGAINST THE FREE LICENCE OF ANTIVIR, THIS IS ONLY A PROVE OF CONCEPT!
If you are annoyed by AntiVir's (
http://www.avira.com/) Update Notifier you can block it very easily if you own WinXP Pro(It also works on Vista and Windows 7):
The notifier is just a file that can be blocked from starting.
Just goto Start - Run and type
Code:
secpol.msc /s
and press return.
Now you goto "Software Restriction Policies"(
http://technet.microsoft.com/en-us/library/bb457006.aspx). If you never worked with that before you we'll need to activate that. Just make a right click and "create restriction policy".
Now goto additional rules, make right click in there to create a new "Pathrule"
Goto your AntiVir Path and search for the "avnotify.exe" (ex. "C:\Program Files\Avira\AntiVir Desktop\avnotify.exe")
Now select "not allowed" from the dropdown, press ok and you are ready.
