General Software Discussion / Does reliable PC security have to cost money?

A friend of mine brought over his virii (yup, there were plenty on board) infected external USB drive and plugged it into my laptop. Avast Home edition (free) was running, up to date with the latest definitions (updated daily). Before I knew it, I couldn't open msconfig or regedit from Win + R or any other way. A bunch of files called hfhludy.exe and meex.exe copied themselves to every freaking drive on my computer and the network. Needless to say, those on my network were not pleased.
I find this virus interesting because its also like a Trojan. If I went to Google and searched for how to remove it, it would close my browser (Firefox and Opera). If I tried to go to TrendMicro's Online Scanner, it would close the browser window again. It added two processes to the startup. Since regedit didn't work, I used Spybot S&D to disable them, but they appeared again on startup. Deleting or replacing the autorun.inf file in each drive did nothing either.
The bottom line is : Avast Failed against the TR/downld.B Virus. But, both AVG and Antivir were able to detect it when I plugged in the Hard drive into another computer through an external case. This isn't the first time. I've had the flashplay.dll worms on my computer from USB thumb drives and Avast kept scanning them, but said they were okay. It was only a week later that the worm was added to the virus definitions.
An anti-virus is only as good as it frequently updated by its manufacturer. I liked Avast and recommended it to all my friends whose machines I've fixed, but I will be emailing them with an advice to switch to AntiVir or AVG at the soonest.
Perhaps, it is indeed fallacy to think that free anti-virus solutions will stand up to their commercial counterparts. Multiple layers of defense by installing several anti-virus programs would be nice, but I've encountered conflicts while attempting that in the past. Not to mention the added resource overhead, which an old machine like mine does not need.
