First security fail found in Windows 7

Tip: Click here to update all your PC's outdated driversThe good folks at F-Secure uncover the first Windows 7 security fail … and it’s a classic.
The issue in question is nothing new. In fact, it’s been around for so long that I didn’t even bother checking to see if it had been fixed.
You see, in Windows NT, 2000, XP and Vista, Explorer used to Hide extensions for known file types. And virus writers used this “feature” to make people mistake executables for stuff such as document files.
The trick was to rename VIRUS.EXE to VIRUS.TXT.EXE or VIRUS.JPG.EXE, and Windows would hide the .EXE part of the filename.
Additionally, virus writers would change the icon inside the executable to look like the icon of a text file or an image, and everybody would be fooled.
Surely this won’t work in Windows 7.
Lets try.

of course it will work.. but so??.. the antivirus will detect it anyway.. it's only
invisible in the explorer, not in file system level, this is stupid.. it's like saying
"hey.. i can infect a computer that doesn't hav an antivirus.. yay!!!".. stupid...

i can't stand hiding extensions of known file types. it drives me crazy. i don't see
why you would want them hidden. is there a reason for it?
everything that the os interprets as an executable should have a glowing rectangle around
its icon. it certainly would make me suspicious to find this glow around a text file...
wtf is wrong with people. i'm by no means in favor of this "feature", but this is not
a security flaw. if this is the worst part of windows 7 thus far, then microsoft has done
an excellent job.
guy, i feel your pain. it drives me crazy as well.
if they can't even fool explorer to list the type as text-docement
seriously
you're bound to notice a .txt extension while all the other extensions are hidden, and
the file type saying application...
i hate having extensions hidden. i always disable the hiding of known types. problem
solved
well, many noobs never tweak thier windows, you'll see how amazing except from us nearly
all of your friends didnt do a thing to make windows better but make it worst.
myself rename extensions and view them all the times, so this is not a deal, and i have
good antivirus would have pick it up anyway, unless is spyware then that's another story.
*yes av doesnt pickup minor spywares/adwares*
anyone that posts this as an error or flaw in an os needs a good kicking.
in a
corporate environment users don't always understand file extensions, and they don't need
to if admins are doing their jobs, thats why there's the option to hide/show them.
not an error but an optional feature.
virus checkers check all files anyway if
users configure them correctly.
this is an 'option' people not a security
vunribility.
not a bug, not an error, not an oversight.
it's a user option down to
personal preference.
just select the option you want and shut up!
does it really effect you if someone else hides their extensions on their own pc? i don't
think so.
windows 7 is still in development of course there are some known bugs like previous
systems. so until the bugs have been fixed stick with xp.
