Hi, all. Decided to try out Avast 5 when it was released and have been pleased so far. I was wondering though, what you all suggest as far as hardening/securing Avast's settings for optimal protection/optimal performance (speed). For example, do you select 'all packers', set heuristics to high or normal, use transient/persistent caching. And also what are the drawbacks/advantages to using your specific settings. I'd like to get a good discussion going on this subject. Thanks a lot, and love the site.
