HELP! Computer idiot here. Recently loaded free version AMG virus scan and it says I have the trojan horse downloader virus. I've not noticed any difference in the way the puter is working however. When I try to move it to the virus vault, msg pops up that it cannot be moved. location is C:\_RESTORE\TEMP\A0155409.CPY There are actually 7 of these locations all the same except last 3 digits go from 409 - 415 and the virus name is the same except for the last letter (i.e. dyfica.p or dyfica.q) etc. The letters are Q,P,I,K,E,G,G.

This is my first time to this site - all help will be greatly appreciated. If you need more OS or CPU/RAM info and you'll tell me where to find it - I'll gladly supply the info. Thanks!!!

I saw this addressed once before, but, being a computer dummy, not sure if that answer was appropriate for my situation.

P.S. I've downloaded the Hijack program I've seen referenced a few times, however don't have a program on my puter to unzip it. <sigh> Anyone know of a good freeware zip program?

hi carole,
try this:

Remove these registry entries if present:

HKEY_CLASSES_ROOT\clsid\{405fd721-04ef-4ef2-ab96-fb31d32d4643}
HKEY_CLASSES_ROOT\clsid\{a0f0d762-d1de-43af-b70e-d87864743eb3}
HKEY_CLASSES_ROOT\clsid\{f7f808f0-6f7d-442c-93e3-4a4827c2e4c8}
HKEY_CLASSES_ROOT\clsid\{8f4e5661-f99e-4b3e-8d85-0ea71c0748e4}
HKEY_CLASSES_ROOT\typelib\{8f4e5661-f99e-4b3e-8d85-0ea71c0748e4}
HKEY_CLASSES_ROOT\typelib\{f7f808f0-6f7d-442c-93e3-4a4827c2e4c8}

Remove these files if present:

Open the 'Downloaded Program Files' folder and delete the entry for 'NSUpdateLiteCtrl Class' (NSUpdate variant), 'NSLiteUpdateCtrl Class' (NSLitevariant), 'MoneyTree Dialer' (UniDist variant), 'MultiDist' (MultiDist variant), or 'Software Update Manager' (DyFuCA variant).

kill these running processes with Task Manager:

programfilesdir+\dialers\stmtdlr.exeactalert.exe
optimize.exe
stmtdlr.exe
view_sex_now.exe

or if found:

bl-install4.exe
blss.exe
installer.exe
removeme.exe
safesurfing.exe
ssupdate.exe
un-bl.exe
updaterinstall_102.exe


Follow these steps to remove DyFuCA/Internet Optimizer from your machine. Begin by backing up your registry and your system, and/or setting a Restore Point, to prevent trouble if you make a mistake.

Unregister these dll's with Regsvr32, then reboot:
nem214.dll
iopti130.dll
nem207.dll
nem210.dll
nem212.dll
wsem210.dll

hi carole,
if the above manual delete is too complicated for you, why not try downloading a copy of Spybot, and Adaware, both will help you solve the problem.
also download a free copy of A2 anti-trojan, you can find the link at www.thepublicworks.com as for getting a free zip program, go to www.webattack.com and link to freeware, look under zip software.
all the best,
murve

Hi all,

I'm new here like Carole and I've been trying to rid my PC of Downloader.Dyfica.v for several days now. My AVG program spotted it but couldn't delete it. I downloaded and ran two Trojan removers and they couldn't even find it. I've tried Spybot as well. :( From what I understand, this trojan monitors your internet activities and doesn't screw with any programs. But still, it's annoying, to say the least. I remember when I had the Blaster, I went to Norton and they had a patch/fix to remove it. Could they have the same for this little culprit? Thanks.
