The main problem with drivers is, they are easy to install, but often quite impossible to get rid of. Another problem is, many many if not most problems are referred to as driver problems, and it's not necessarily true. Many other factors have an impact too, say, Codecs. Like the Virus thing, I'm highly annoyed by the fact that system problems are straightly pointed out as "IT'S A VIRUS!!!!"
I've been using DriverMax for some years, I find it reliable, but it has had its bad moments. And one should never update more than one or two drivers at a time, and never forget to create a Restore Point. And then, check system works, from Device Manager too. And, I tried an updater, and it was horrible --- it showed that some 90% of my drivers were outdated... not true, not true.
I agree with bassfisher, in basics. Taking a shortcut is fast, but it may mean fast money out of one's pocket. I'm "both and" here. The main word could be caution. Having a driver's license doesn't really qualify you as a dragster driver, eh?
