--- TIC-TECH message:
In general it is a good idea never to open any email attachment with a
filename ending in ".exe" unless you know exactly what it is, i.e. something
you specifically asked someone to send you. Files ending in ".exe" are
executable program files, and opening them executes them. Never open an
attached file with a name extension that doesn't mean anything to you.
Here are some common types of files that are safe to open:
images (.gif, .jpg, .bmp)
sound and video (.wav, .mp3, .ram, .rm, .mpg, .mpeg, .avi, .asf)
web pages (.htm, .html)
plain text (.txt)
Adobe Acrobat files (.pdf)
Some of the above types might not open on your computer because they require
specific programs that you might not have. For example, without the Adobe
Acrobat reader you cannot open .pdf files. But none of these will harm your
computer because all they can do is be displayed (or played).
Potentially harmful files include:
.exe - executable programs
.vbs - script files used by Internet Explorer; can contain harmful commands
.doc - Word files, can contain harmful macros (small programs embedded in
the document)
.xls - Excel files, can also contain macros
Word 97 and Excel 97 and newer versions have built-in security features that
warn you of the possibility of macro viruses.

Hi All,
Do not open any attachment named Navidad - it's about a 2mb .exe file
for Windows. And it is indeed a virus. I've got two of these in the
last few days - and I've noticed many other educator-type addresses in
the "To" field - including several from our school. - Mark
