Security Question

[Mr. Monsieur]

Hey folks!

My apologies in advance if this question is retarded...I went looking for an answer and, unable to find one, I decided to post...

Is it possible for someone within 30 feet of me (say, at a coffee shop) to access my laptop even if I have airport and bluetooth turned off? Some weird things have been happening in said situation, and this was the thought I had...that somehow someone in the coffee shop was accessing my computer. The only utility (I believe) that might still be running in the background is a Lexmark program for connecting wirelessly to my printer when at home.

If this is, in fact, possible...how? What should I do to protect myself? And is there any way to check (through Console, maybe?) if someone has gotten in?

It is NOT possible.

There are currently no viruses for Mac OS X in public circulation, only a handful of trojans and other malware, which have to be installed manually via entering the administrator password.
The only anti-virus you need to protect your Mac is education and common sense.
Also know, that the term "virus" is often used to refer to other kinds of malware, but there are differences, which you can find out by reading the following:

Only if they have an arm that's 30 feet long.

That utility is useless away from your network, as you can't connect wirelessly to your printer or anything else with AirPort tuned off.
