In my nine years of using OS X I have never been infected with any sort 
of malware. Yes when they spoof your email address to send spam, or send 
you spam that appears to come from your own email account, it is 
disconcerting at first until you realize that it was just a spoof.


I have run ClamXAV here and there and the only thing it ever found was 
something in a Windows font application, never anything that was even 
capable of running on OS X.


I do seem to remember once reading about a malformed .jpg that was 
posted in some Mac forum pretending to be some sort of spy shot of new 
Apple hardware or something, and again a QuickTime 'updater' that some 
adult site would try to convince unwitting OS X users to install, and 
there were allegedly some infected copies of iWork or CS or something 
floating around the bittorrent world. Download known software from 
legitimate sites and you'll be ok.


The biggest risk as others have mentioned is phishing. When someone asks 
for your personal information think twice before you hit the submit button.

 Any day now.


I do wish you'd let those wonderful IT folks know about your discovery. I
was delighted to discover recently that my company has finally adopted a VPN
client that is supported on the Mac...but that requires antivirus software
be installed on your Mac.Doh!

Er... Adrian... cold virus? It was a joke, of course, although not a
good one.

Personally, I used ClamXav for a while when I first switched from
Windows, until I finally realized it was a waste of RAM and
uninstalled it.

The OP seems to have several problems, all apparently unrelated, but
until we get more info, like Bruce suggested, it's all guesswork.

We took a poll years ago on the PCI list. Out of responses from that list
and soem who responded with figures from other lists of about 2,500 listers
only one real virus was found and that was something a company cooked up to
scare Mac users into buying their product.

And I read nothing of the current state of affairs to lead me to believe
this has changed. If Mac OS X infecting bugs are out there they exist to
sell preventative software.

I'm sure Bruce or someone who must administer IT for a large installation
will set the record straight if this is wrong.

Oh boy. Here we go again.

By the way, nowadays viruses other than malware are usually nothing
more than that: something a company cooks up to
scare computer users into buying their product. And the most effective
forms of malware are not viruses, but phishing, which require you to
actively go to their fake websites and voluntarily give them all your
personal info --something that afflicts PCs and Macs alike.

 I'm sure Bruce or someone who must administer IT for a large installation
 will set the record straight if this is wrong.

With the caveat that Anecdote != Data :

I've been using Macs since 1987, and helping to administer a reasonably large 
institution's (mainly WIndows-based) systems since 1994. 

In all that time:

There have been occasional proofs of concept malware releases for OS X, but 
they have never propagated very far, if at all. I've never seen one in the wild 
here.

All the malware that our current AV systems see are 100% Windows-based. (and 
they do have the Mac malware profiles included) The ONLY stuff we've ever 
caught on Macs are Windows-oriented email attachments that came in on HD's from 
other institutions.

I have *once* run into websites doing funky stuff to Mac-identifiable web 
browsers, that was about two years ago, and it didn't last very long.

I've twice run into seriously malformed malware websites that have tried very 
hard to convince me that my C:\Windows directory was infected with a long 
list of nasty-sounding bits of software.

I got the WDEF virus spread pretty nastily through my stack of System 6 floppy 
disks, which updating to System 7 cured.

That's about it.

I never got caught by the later classic Mac viruses because all you had to do 
to avoid those was turn of Program Autoexecution in the Quicktime Control panel.

I've been told that you can occasionally find Word Macro viruses lurking about 
in old, moldering software and mailing list archives, although those may also 
be ...and then they found a HOOK in the fender of the car!!! tales.

I keep getting told by authoritative folks in the IT industry that there will 
be a flood of OS X malware any day now; I've been hearing that for ten years.

Any day now.

(and it's not a matter of market share...I've witnessed a bit of PC malware go 
around that was aimed at a specific firewall product that probably had a 
worldwide distribution in the low 10,000's of copies.)

First things first.

First of all,tell us what Mac, what version of the OS you're using.

I can state that the email message in your sister's email box almost certainly 
(99.%) did NOT come from your computer...spam just doesn't work that way 
these days. The From: line is almost certainly forged.

Second the date being wrong is more likely due to a dead PRAM battery, and your 
normal wireless network wasn't enabled for some reason? There is no dialog I 
can think of you could get that would ask abot 'allowing or denying' incoming 
networks.

Tell us *exactly* what the error says.

Finally, the odds are enormously *against* you having a virus on your mac.
