They're not being a 'n00b' at all. Granted, they should have consulted the FAQ before posting, but I can see why someone might not. After all, there's no way to know what data an FAQ contains until it has been read, and that requires a commitment of time a user can't judge worthwhile. This is the reason that documentation always fails - not because people are stupid, but because they're employing unfortunate-but-necessary heuristics that win out in the vast majority of circumstances.
It's so rare I yell at my monitor in disbelief. But, here we are. I, too, can see why someone won't read a FAQ or a read me, or instructions, or remember to bring a coat with them to the arctic circle. That does not mean the behavior should be tolerated. Let's follow the thought process involved in this specific circumstance:
1: They won't spend five seconds searching for "virus". They won't do this even through the first paragraph of the thread mentions a FAQ.
1a: If they don't search the FAQ because they've determined beforehand their problem won't be mentioned, they're assuming things. Their problem is unique, the author hasn't made good documentation, etc.
2: They will spend several minutes composing a post asking a question that's already been answered in the FAQ they refused to check due to one of the above reasons.
3: They've determined it's easier and quicker for everyone to ask a question and make someone else spend their time and effort helping them.
This tells me the person's judgement is garbage and/or they don't value other people's time and effort. The n00b label fits. As far as I'm concerned, they don't deserve to be treated nicely. If punishment is too harsh, then they should just be ignored; they don't deserve help as they've done nothing to help themselves first.
