For what it's worth...
I've worked with computers for many years... I'm am the support staff at my place of business and as such I deal with the support departments of MANY pieces of software. In my opinion, AVS support is sub-par in terms of time it takes to get a response. I also think they can be a bit gruff sounding in their responses. At times it almost seems like English isn't the support staffs primary language. Maybe I'm way off on that... just a feeling I get. Maybe it's because I'm American and can't understand good British English! :)
Anyway, despite the negatives, there are some good positives about AVS: First and foremost is the price. The amount of software you get for such a low price is really amazing. If you want top notch support, you can expect to see the price rise substantially AND no more free updates for life (if you bought the unlimited package).
Second, as for the time delay, I take it with a grain of salt... how many times have you contact support for a company about a problem and you get a response within hours telling you to do this, that, and the next thing... but when you do that, it doesn't do a thing to fix the problem? Worse, you already indicated in you original contact to them that you did those steps, but they tell you to do them again, and won't move to the next level until you do? This is because their initial support is a bunch of low paid people who don't know the product at all and just go through a list if "This to do if it does work..." They make you go through the stupid steps one by one until their list is exhausted and then they move the problem up to the next level of support, which usually takes a couple of days to get back to you. I feel like AVS has skipped the middle man so to speak. You don't have to work through the rapid, but useless, support response.
Just my opinion of course.
Now, as for facts: I've emailed the company and also posted a couple of questions here in the support forum. I think my email took about 4 days to respond to. Forum posts were much quicker... usually less than 48 hours. I would strongly suggest using the forum for two reasons: Appears to be faster service from AVS and if you post it here, other users who may have already dealt with the same problem might be able to help you even before AVS is able to get back to you.
