csrss.exe not found

[Dakota_98]

I managed to infect this computer with a worm and now at startup I get this message followed by one referring to the registry. Is there anyway to fix this other than reformatting?

Could it be this? http://securityresponse.symantec.com/avcenter/venc/data/trojan.webus.html

[Dakota_98]

Sorry, I should have said that I've taken care of the virus, now I'm working on getting things back to normal.

[andyman]

it's actually a good thing this means the worm can't start.
but it's not all clean yet

[andyman]

have a look in your Favorites for any rouge links

[Dakota_98]

Well I've run Norton, adaware, ewido, ccleaner and I'm down to one instance of csrss.exe running from 3. In Task Manger it is running, but I get the same alerts at startup.

[frostyone]

Post a Hijack This log here.
We can look for the startup entry, then remove it.

Just copy/paste the log.

[mander]

Check the registry for the qv... thing and delete it. it might be there in several places so I would delete them all. reboot and see what happens.

[Dakota_98]

is this what needs to be fixed?

[frostyone]

Hang on Dakota.

1 entry may be difficult to remove.

You also appear to have some other spyware, probably as a result of Messenger plus 3.
Did you REFUSE to install the sponsor?

[Dakota_98]

not that I know of Frostyone. I don't know what the sponsor is. I'll go back and run it again

edit: I ran it again and I see no mention of sponsor so I don't know what you mean.

[frostyone]

Ok Dakota.

You should uninstall Messengerplus3 using add/remove programs.

Print this out.
You won't have internet in safe mode.

Then boot into safe mode

Scan with HJT.
Place a checkmark beside these entries:

R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = http://smpbnhoiietjedtwrmiu.com/ksT...uQmCF8QHL8.html

F3 - REG:win.ini: load=C:\WINDOWS\system32\qvfqqfrcgb\csrss.exe
F3 - REG:win.ini: run=C:\WINDOWS\system32\qvfqqfrcgb\csrss.exe

O4 - Startup: csrss.lnk = ?

Click Fix checked, then reboot normally.

Scan with HJT again and post the new log.

(You may receive an error message about O4 - Startup: csrss.lnk = ?)

We can reinstall Messengerplus3 without the sponser later.

[Dakota_98]

ok...I'll be bock ;)

[Dakota_98]

computer is starting normally now...thanks frostyone!
