Have you received email saying "Send This to everyone you know"
Well don't!!  what a way to make enemies of all your friends.  How do you know these messages are not full of viruses.  think before you follow instructions in emails and do not delete anything without double checking at decent web sites.

The offending messages often start with -
"Please forward this message to everyone you know, then delete all the files on your hard disk. Thank you for your cooperation"

Well, a few months ago a nefarious netizen took the "honour system" virus joke, rewrote it, and created an equally fake virus warning that many newbies have taken seriously. The new warning asks you to scan your hard drive for a file named SULFNBK.EXE and, if you find it, to delete it from your system.

What the virus warning fails to tell you is that SULFNBK.EXE is *NOT* a virus, it is a Windows utility used to restore long file names in the case of a catastrophic crash. DON'T DELETE THIS FILE, FOLKS.

Fortunately, SULFNBK.EXE isn't an "essential" Windows file -- you can actually live with out it -- but you'll never catch ME saying that out loud.

Long story short: if someone sends you an email that asks you to do *ANYTHING* -- invest money, sign an online petition, warn your friends about a new virus threat, delete files from your Windows system folder, forward information to everyone you know, yadda yadda yadda --   take two seconds to verify the contents of the email before you do ANYTHING! It is so simple to do, and it keeps you from making a fool of yourself in front of the entire planet.

For example, a simple search at http://www.google.com/ for "SULFNBK.EXE" results in 13,800 hits, and EVERY ONE of the first 10 hits shows you that that the SULFNBK.EXE virus warning is a hoax  See also http://www.netsquirrel.com/combatkit telling you how to restore SULFNBK.EXE in case you were foolish enough to delete it.) Two seconds of work and you keep from damaging your system.

By the way, another great hoax-debunking resource is The Urban Legend Combat Kit at http://www.netsquirrel.com/combatkit/

IE 5.5 and IE 6.Patch For Windows
Eliminates three newly discovered vulnerabilities."  Microsoft considers this patch to be critical and recommends that all "[c]ustomers using IE should install the patch immediately," partly because of the severity of the three newly discovered vulnerabilities
that the patch eliminates.  This patch is only for Windows-based versions of Internet Explorer. If you have a PC, you *NEED* this patch. If you have a Mac, you don't need this patch -- these security hole exist only in the Windows versions of Internet Explorer.
