Hi there.

Sorry for posting in english, but this is the only group I've found
that's referred to this problem recently. I don't know if this problem
has been solved yet, because I can't read french! hehe.

A few days ago, I got this problem of my home page (using IE 5.01)
being constantly changed to LuckySearch, or something, after I
rebooted.

I tracked down the problem to a file called tapicfg.exe in the
windows\system folder, with a 'run' entry in the registry. The give
away that this file was probably not a windows file, even though it
had the same date/time as Win98se files (I'm using Win98se), was that
it was in lower case :-) and therefore a 'long file name'.

This didn't solve the problem after all, as the tapicfg.exe was being
replaced on reboot. So next I found all the files on my system that
were also 57344 bytes (and there were quite a few!), and using 'fc' I
compared them to tapicfg.exe. Finally I found this file...

C:\Program Files\Common Files\Microsoft Shared\MSINFO\info32.exe

this file is identical to tapicfg.exe, except the name, and is NOT
anything to do with MSINFO. It was not being run from the registry,
but from WIN.INI. It changed an entry in WIN.INI...

from this...

[windows]
run=hpfsched

to this...

[windows]
run=C:\WINDOWS\..\PROGRA~1\COMMON~1\MICROS~1\MSINFO\info32.exe
hpfsched

(Note: the above is all on one line)

hpfsched is something to do with my printer, a HP 610C. Obviously the
info32.exe is replacing the tapicfg.exe, and also executing the
hpfsched.exe printer program.

Hopefully thats all there is to it! In summary, remove these two
files...

C:\Program Files\Common Files\Microsoft Shared\MSINFO\info32.exe
C:\WINDOWS\SYSTEM\tapicfg.exe

also edit your WIN.INI file to correct the 'run=' line as appropriate,
and use msconfig.exe to delete the 'tapicfg.exe' run entry, or remove
it from the registry using RegEdit.

Thats all for now.

Salut,

You should change your browser and switch to an IE6 up to date.

This didn't solve the problem after all, as the tapicfg.exe was
being replaced on reboot.


Of course, it was in memory. You can try after booting in "safe
mode" (F8 key just before the windows startup screen).

You can send a copy here: so we will have a name
for this malware.

Why do you use IE 5.01 ?

Maybe it's better not to know to read it :-). Not very much stuff
interesting these days over there...

As another one said to you: you should update to IE6. More safe...

It can be a Windows package file :o). Check here:

You need to kill the process either otherwise it's useless, it copies itself
again and again into the registry.

were also 57344 bytes (and there were quite a few!), and using 'fc' I

Hehe

Yes. It's a TSR from HP. If I remenber well, it has something to do with
cartridge management.

Obviously the
info32.exe is replacing the tapicfg.exe, and also executing the
hpfsched.exe printer program.


That's it dude.
Actually info32 is just a pathetic trojan. If you need more information why
don't you just click these link?

Hello,

Ce n'est qu'à partir de la v 5.5SP2 que la faille MIME peut être corrigée,
de mémoire.

Mc, pas Mac scrogneugneu !

Cette atteinte, cette aggression caractérisée envers ma personne est tout
simplement inqualifiable ! Il est clair que sous couvert d'anonymat tu ne
cherches qu'à me dénigrer. J'estime avoir le droit de traiter tes propos de
diffamatoires. Tu n'es certes que le sommet de l'iceberg de toute une meute
veule et servile vendue à une puissance étrangère, mais je ne m'y trompe pas
! Je vois clair dans tes allusions calomnieuses. Tu cherches à porter
atteinte à ma réputation. Et, par là, à faire passer l'éducation nationale
française dont je suis issu pour négligeable vis-à-vis de celle dispensée
dans les pays des sbires dont tu es à la solde.

Voir des traîtres à la nation de ton accabit me dégoûte. Tu es directement
responsable, de par tes actes, du chomâge de milliers de personnes que tes
critiques infondées rabaissent aux yeux de l'opinion publique friande de
racontars de gufusses de ton espèce. Si tu ne cesses pas ce harcèlement, tu
devras rendre compte de ton attitude méprisable devant la loi. Sache pour
autant que je ne te laisserai pas insulter ma personne, mes compétences et
mon savoir de manière aussi gratuite. Je rendrai coup pour coup. Vous
n'êtes, après tout, qu'une petite poignée de renégats ! Quantité somme toute
négligeable comparée à l'océan d'esprits libres dont je me targue de faire
partie.

À mes yeux, tu n'es qu'un veinal vendu tout entier à une société de l'Est
dont je préfère taire le nom. Mais qu'elle sache que les tentatives d'une de
ses taupes pour arroser les intervenants de ce NG à coup d'hectolitres de
Leffe n'ont pas trompé mon esprit alerte et avisé. Je continuerai mon combat
pour que le public soit toujours informé de vos projets bassement
mercantiles. Et ce ne sont pas quelques veules adorateurs du veau d'or
lâchement planqués au pays de l'Oncle Sam qui interrompront ma lutte. Le
public a le droit et doit savoir !

:o)

(désolé pour AMcD j'ai pas pu m'empecher:-))


Ben moi non plus. On s'y croirait non ?

Hello,

stop, n'en jeter plus... j'me rends

c'est juste parce que j'avais fait un test en ligne depuis un IE 5.01 (de
base / w98se) et que c'était négatif (m'enfin, comme j'ai pas de
protocole...)

j'ai un IE 5.5 (jamais installé directement de SP) patché de tous les
côtés... et je ne saurais dire quelle est sa "version" exacte :-(

mais bon, amha, si il y a moyen de patcher/configurer correctement une
version "stable"... c'est pas obligatoire de passer à la dernière version
(pleine de failles passées, présentes et à venir)
sauf à vouloir bénéficier des nouvelles technologies M$ :-?

désolé si tout cela semble aller à l'encontre des conseils donnés
habituellement (ie "mets d'abord à jour ton IE tout troué")

Well maybe IE6 is 'safer' but probably not for long. I have a very
slow comp (by today's standards), and I've tried IE5.5 but found it
generally slower than IE5.01.

How does IE6 compare to IE5.5? Is it similar speed and reponsiveness?
Is IE6 stable now? I read the first release was very buggy. Also are
there any problems to do with IE6 not having java or whatever?

Maybe I should just stop using IE and try Mozilla (Firebird?) or
Opera?


I tracked down the problem to a file called tapicfg.exe in the
windowssystem folder, with a 'run' entry in the registry. The give
away that this file was probably not a windows file, even though it

I'm certain 'tapicfg.exe' is not anything to do with windows or IE,
because I have a simple version of the linux 'locate' command (wrote
it myself using C++, you wouldn't be impressed by it though :-) ), and
it makes a database file of all the files on my system. Basically,
tapicfg.exe was not in this database which was updated a few days ago.

This didn't solve the problem after all, as the tapicfg.exe was being
replaced on reboot.


You need to kill the process either otherwise it's useless, it copies itself
again and again into the registry.


Maybe. I forgot to check all the 'hidden' processes that were running
while I was sorting this out. It seems to have gone now, and it's not
in memory now.

Obviously the
info32.exe is replacing the tapicfg.exe, and also executing the
hpfsched.exe printer program.

OK thanx everyone for replying :o)

I'll try to post the tapicfg.exe file to that email address that
someone else suggested.

Also, I've downloaded HijackThis and i'll check it out soon.

That's all for now.
