A few questions concerning Avast... 1- What added benefits are offered by Avast's paid version in comparison with its free version? 2- Does Avast actually have heuristics capability? If so, how good are Avast's heuristics in comparison to (SUCH as) F-Prot's heuristics or DrWeb's heuristics? 3- Does Avast have good & plenty unpackers, or... not? 4- I understand that Avast has several *extra* modules, over & above its anti-virus module. "Web Shield" is one example of those extra modules. Can the extra modules be easily disabled? 5- I prefer to update manually. Can I easily disable Avast's automatic/scheduled updates? 6- On average, how often does Avast update its (a) signatures? (b) engines? 7- Do I have to use Avast's "mod-type" GUI, or are there alternatives? If there ARE alternatives, can they be easily put into operation? 8- Is Avast's excellent support forum its only means of providing tech support? In other words, will Avast answer e-mail queries on tech support matters, or do they insist that such matters be exclusively handled by the forum? 9- How does the numeric size of Alwil's staff compare with the staffing of the "big dudes" such as Symantec, Kaspersky & McAfee? I am considering Avast NON-free as the replacement for my current paid AV. Ergo, any additional comments or suggestions you might care to make concerning the Pros & Cons of Avast would be greatly appreciated.
