Help, I'm being attacked!
 

Hello boffins,

For some reason, a file keeps getting copied / installed to this location on my Win2000 machine.

C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\683e8586.exe

It also finds its way into the registry under HKLM/blah blah/RUN_ONCE under the value name sys1612188 and command line
C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\683e8586.exe


Microsoft's antispyware blocks this registry key, but it also appears in HKEY_CURRENT_USER and runs! It can be stopped using the task manager. I've looked in the file using a hex editor, it's only 8k but there's a print, SOCK, RasEnum and MSVCRT.dll all mentioned in there.

When it runs, there is initial network activity, and it seems to start up ntvdm.dll (and wowexec.dll).

NAV is up to date and shows everything is clean.

Any thoughts? The only thing I installed recently was a shareware/demo version of a winRAR unzipper. It has since been uninstalled.

Can't find anything on 683e8586.exe but there is this from the microsoft knwledgebase http://support.microsoft.com/kb/q196453/ doesnt seem to be on all fours with your problem though. Also it states that it applies to win2000 servers.

Have you tried to "roll back"?

Actually it looks worse than I thought....

The mere mention of RasEnum and MSVCRT.dll scream out to me that you have a virus infection. The .dll is a visual basic entry and rasenum collects data from your address book. Hhhhmmmmm.

Opened any strange emails about Anna Kournikova recently?

I just don't get why your AV program doesn't pick up on it.

I haven't opened any dodgy emails, but I'm now installing sygate's personal firewall in the hope that it may close any backdoors I may have.
I might try copying the file to another machine with WinXP and McAfee to see if it picks it up.
I'm also running ad-aware which shows nothing out of the ordinary.

Go here www.webimmune.net and submit the file.

McAfee doesn't detect it either :(
Hopefully it won't come back with the firewall installed.

Done. :)
Will they get back to me, or is it a black hole?

They'll get back to you.

Hello Jack,

I received an update for McAfee in the form of a dat file, which detects this file, but, I can't use McAfee on my main machine as it interferes with another program which needs to access a remote network.

Sygate firewall tells me the file is trying to access www.google.com (216.239.59.104) using remote port 80.

Any thoughts on why it would want to do this? Thanks.

What does McAfee report is as ???

Probably searching for new addresses to infect from your machine.

Proxy-Agent

Proxy-Agent is very old so cant see why ????????????

Depends on the variant Nick, .e was last week.
