I had AVG problems with the last build & worked along with AVG technical who
could not reproduce the error on load. I tried everything but with UAC
enabled AVG produces this error.
I installed the free version this time with the PreRC1 worked fine last
night on rebooting but have just booted now to find the same error
When I uninstalled the last time I installed PCCillian also and did note 2
AV's reported - I actually thought this was because I had AVG installed on my
first hard drive with XP Pro on it. I am about to uninstall again as I came
here to find out if there was a lighter AV than PCCillian.
When I ran all the tests last time I did note some files where locked hidden
and my Registry cleaner wasn't allowed access to them - this is possibly why
you have the multi AV showing (I will have too when I uninstall)
I was able to run PCCillian without problem even with the dual AV report by
Defender. I thought AVG would be fine this time but

just found out it's
not.
