I started my one self-educated man consulting business over 20 years ago, and the "we" refers to the many other good people in the business that I know and share the good and the bad with, as they save me time by sharing their own good and bad experiences with me. None of us can do it all any more. There's just too much round to cover now days. Once I find a product that works and doesn't cause me undo embarrassment in front of customers, I learn as much as I need to about it to serve my clients, who are 100% commercial businesses.
I dropped home users after the first three months in this business, because they ask unending questions for which they can't afford the answers. Compared to my business clients, who basically only want their office staff to be happy. Beyond that, they have their own work to do. For the most part, they just want me to get finished as quick as I can, so they can pay me and be done with it. They want to get back to making money doing what they do for a living, instead of spending time and money with me.
They, along with those I know who are also in this business in one way or another (some working for large companies, some running smaller businesses like mine) all trust me. As I trust them, when they've learned about a product or service to use or avoid, as the case may be. And when they, or I, have to switch from one vendor to another, the majority of us follow the leader - who ever discovered the reason we should make such a change, and go through learning about yet another product or service, to cover the exposed need.
As far as Avast! is concerned, yes I have a copy of v4 here. But, whenever I try to go back to it, and enter the new registration code which also became due at this particular moment, it immediately upgrades itself to version 4.18 Pro, and then won't let me access the Virus Chest, by refusing to run with the registration number which it claims to have accepted, but now it rejects. I'm fed up with this. Many others are having problems with this upgrade, if you read the posts.
There should always be a path back to safe ground, no matter how small a change is being made. People have businesses of their own to run, and often can't afford to take unscheduled time off to deal with something like this. I'm under my own very important deadlines right now, and I definitely do not have the time right now, either. In fact this, together with one other item, have already pushed me past the current important deadline I mentioned, which is the main reason for my angry attitude on this. It's uncalled for, to block access to what works like this.
By the way, for DavidR, you're right, of course. I did forget to mention that Monday afternoon for me is in the GMT -8:00 time zone. And the OS is XP Pro, SP3. The other little item which causing me problems right now, when I really don't have time to deal with it, is the first ever catastrophic failure of my own personal system, which I also have to recover some files from soon. Thanks for your attention..
