Spiritsongs,
1. During the last year, GMER has vastly improved.
2. Saying that a certain program is BEST is of of course always a bit exaggeration (there's nothing like BEST antivirus, BEST firewall, BEST antirootkit etc.) but what I said is my personal oppinion based on certain facts and some personal sympathies.
3. I don't think the threads over at Wilders' (that you linked) indicate that GMER is "not the best". The first one doesn't mention GMER at all and the second one is of these super-lengthy threads that never lead to anything...
4. The test carried out by informationweek (mentioned in the thread on the avast forum) is definitely NOT something I'd base my judgements on... Compare this to magazine tests of antivirus software.
Cheers
