I have repeatedly attempted to obtain a trial key for VBA32. I sent messages to the link indicated on their website, but received no reply. My daughter said I must have done something wrong, so she tried it. She didn't get a reply either. Therefore, the only trial they offer is cripple-ware. Namely, the "demo" version of VBA has its cure abilities and its heuristics disabled. The inability to test-run the heuristics is bad for at least 2 reasons: (1) VBA's true impact on system resources cannot be determined during the trial, and (2) testing VBA against 0-day is rendered much less meaningful. Perhaps this is one reason why VBA has consistently done so VERY poorly on tests by Shadowserver. In so many words, VBA's forum explains that this situation is necessary to prevent piracy. However, many other softwares allow trials without such a convoluted procedure, so why can't VBA? Further, why doesn't VBA respond to messages that use their link for requesting trial keys? After many months of inability to get satisfactory answers those questions, I give up on VBA. At least for the foreseeable future.
