Do u mean to say that the avast 6 wont work with my version of sp2..
@
ullas,
As already mentioned,
your SP2 version is not the "final" ("STABLE") version of SP2, so you are looking at the problem from the incorrect angle.
Forget about Avast (just for a moment
). For your system to be more stable (and, generally speaking, safer too ), you could uninstall your SP2 (because it is NOT the "stable version" of SP2) and install instead the "final stable" version of SP2 (since you don't want to update to SP3 ).
There are better methods so to gain more stability, but it is OT.
