Having just read through this thread and found a mountain of negative remarks, I just need to add another view to the debate.
After being contacted by AVG and invited to use version 8.0, I eventually installed it.
Sure, it seeemed a bit strange at first, after being used to 7.5, but all I can say to the many sceptics is, just give yourself time and AVG a break.
IMHO it is great.
It updates at the appointed time, scans on schedule and has been very thorough in its' findings.
It has my vote anyway.
