Subject: W32.Novarg.A@mm virus infection
OS: Windows XP home
CPU/Ram: 2392MHz 512 RAM
Comment:

I mistakenly opened a zip file (message.zip, message.doc) that turned out to be this virus (see subject). I don't usually open any attached, but this was a zip from someone I thought I knew so I foolishly did. Norton did not detect it, but when my computer suddenly tried to access the Internet I figured it was a virus and blocked it. An on-line Norton scan revealed this one, with the original hidden away in a temp file (I manually deleted it), and the taskmon.exe file in windows/system32/ infected. I followed the Norton instructions but it cannot delete the taskmon.exe. Nor can I do it manually (and will deleting it not damage Window functions?).

I am concerned about trying to back up then modify the registry -- it seems complicated. But haven't got there yet. First I need to get rid of the virus infected taskmon.exe. Norton told me to deactivate system restore, which I did.

Hope you can help.
Best

Good spot AB.

Lake Sagaris,

Let's have a look..Download 'Hijack This!'. Unzip, doubleclick HijackThis.exe, and hit "Scan".
When the scan is finished, click "Save Log", and copy and paste it in a reply.
http://www.spywareinfo.com/~merijn/files/HijackThis.exe

UPDATE: W32.Novarg.A@mm
It opens a set of ports on the victim's computer and adds several files.

%Windir%\shimgapi.dll
%Windir%\taskmon.exe

If you see an O4 entry in an HJT log for this:

%Windir%\taskmon.exe (Windir is the Windows directory - Windows/Winnt.)

The victim is probably infected. Symantec should be able to clean it soon, and F-Prot's got beta definitions out.

(Note: There is _NO_ legitimate C:\winnt\taskmon.exe in Windows 2K/XP)

Also, it runs through the standard file-search-for-e-mail-addresses routine. Its DOS attack against SCO will last from 02/01 from 02/12, as there apparently is a time limit hardcoded into the virus.
(Information from Symantec's site.)

When I booted up last night my anti-virus
AVG available for free at www.grisoft.com
Identified it and isolated it.
There were 4 files and AVG cleared 3 an the
1st run. After the 3rd run with AVG all 4
files had been either eliminated or healed.
As I have 3 desktops using Win98 second
edition I ran AVG on all 3 and my system appears to be clear
