Ooops, I just upgraded to LimeWire 2.0.2. and even if you choose
not to install all the ad cruft, you still get dldr.exe.

Comviently, NAV spotted it and killed it before it hit my disk ;-)

I'm pretty sure LimeWire is clean, at least the version I'm using
(version 1.6b).  Obviously, I didn't install any of the freebee
sponsor/spyware stuff.

I'm pretty paranoid and though, I'm firewalled and still run ZoneAlarm,
SurfinShield etc.... and also "clicktilluwin" doesn't exist as a raw
(ascii) string anywhere on my system...

Of course, later versions of LimeWire (and BearShare) may/will have
different sponsors, and different "Ts & Cs".

I'm not even positive that it's only one trojan that i
found on my system, perhaps it's two separate viruses,
and i am thinking it's a single one.

In reference to "dldr.exe", i'm not positive where
this came from, but i'm 90% certain that "explorer.exe"
was installed by Grokster (as the Click Till U Win game).
The reason i think that they're both part of the same
trojan is becuase i find "clicktilluwin" in a hexdump
of *both* files - which is too much of a coicidence
for me.

Even if you un-install it, i'm pretty sure it'll hang
around... after i deleted "dldr.exe" and rebooted my
machine, i found it right back in "C:\winnt\"...
as for "explorer.exe" in "C:\winnt\explorer\"
it still hasn't resurfaced after one reboot,
but perhaps it'll come back tomorrow, when i log
into the machine at work again...

Is this in relation to LIMEWIRE?  I have the Dlder.exe file but
no reg entry
under that location or a hidden folder in Winnt called
'explorer' with a
file 'explorer.exe' in it??   If so, I'm uninstalling this shit asap!

Let me know.

thanks,

A concerned net citizen!
