Win32:Agent-MJG[Drp]
« on: November 30, 2007, 10:23:51 PM »
Howdy,

Upon starting one of our computers this morning, Avast detected that a malware dropper, Win32:Agent-MJG, had infected a few of our startup programs. While running a boot-time scan, it found more similarly infected files throughout the drive, including several in the Windows/ and System Volume Information/ directories.

I moved all 29 infected files to the chest as suggested. Everything now appears to be working fine, and a subsequent scan revealed no more infected files. Hurray!

So, I guess my question is: now what?

Sorry for the ignorance, but where do I go from here? As long as everything continues to function properly, should I just assume that the issue has been resolved? Are there any further steps I should take?

Any suggestions or feedback is appreciated. Thanks!

So, I guess my question is: now what?
I suggest:

1. Disable System Restore and reenable it after step 3.
2. Clean your temporary files.
3. Schedule a boot time scanning with avast with archive scanning turned on.
4. Use AVG Antispyware; SUPERantispyware and/or Spyware Terminator to scan for spywares and trojans. If any infection is detected, better and safer is send the file to Quarantine than to simple delete than.
5. Test your machine with anti-rootkit applications. I suggest AVG or Trend Micro RootkitBuster.
6. Make a HijackThis log to post here or, better, submit the RunScanner log to to on-line analysis.
7. Immunize your system with SpywareBlaster or Windows Advanced Care.
8. Check if you have insecure applications with Secunia Software Inspector.

Sorry for the ignorance, but where do I go from here? As long as everything continues to function properly, should I just assume that the issue has been resolved? Are there any further steps I should take? Any suggestions or feedback is appreciated. Thanks!
Ron, asking for learning... where is the ignorance? There isn't. You're on the right place to learn.

Your JAVA is way out of date and could be exploited.

Ensure you have the latest version of JRE (JAVA Runtime Environment) because older versions can be vulnerable to malware. First remove All Older Versions From Add/Remove Programs.

Then get the latest update from here http://www.java.com/en/download/index.jsp

Or JRE version 6 update 3 http://www.majorgeeks.com/Sun_Java_Runtime_Environment_d4648.html

You don't appear to have an active firewall, what is your firewall ?

Upload the file to VirusTotal - Multi engine on-line virus scanner and report the findings here. If multiple detections on VT send the sample to virus@avast.com zipped and password protected with the password in email body and undetected malware in the subject.

A google search on the above file name returns zero hits

Other than that I don't see anything obvious.

Thanks, David.

Not sure how the JAVA got so out of date on that computer. I'll get that taken care of.

I'm not sure what to do with this, though I recognize the myway component as unwanted.

The blwin32 is legit. It's the client app for Booklog, our point-of-sale and inventory system.

Thanks again for the help. It's much appreciated.

I don't recognize either of those, but I'll check with the other users.

OK, run hijackthis again, just the scan element not creation of log, once this is done close any open windows other than HJT.
Look for the entries I said to fix and tick the box to the left of the entry.
Now click the Fix Selected button at the bottom of the window.

That should make a back-up of the changes made and remove these entries from the registry.

The question oldman asks about, trusted sites
O15 - Trusted Zone: *.doginhispen.com
O15 - Trusted Zone: *.whataboutadog.com

I see what he is getting at as they appear to be associated with a trojan, Downloader.Agent.awf, probably something already dealt with by avast. So if 'you' didn't add these to your trusted zone, which I doubt, add these entries to the ones you fix.

Ah, got it. I've fixed all four of those items. No one recognized either of those domains.

Thanks again.

Dell's "My Way"
« Reply #9 on: December 01, 2007, 02:39:13 AM »
 :)  Hi "Travel" :

      Dell puts a definite Adware, and possibly spyware program on their
      computers called "My Way" ; there is Info in the Dell Support Forums
      about removing this at :
      http://www.dellcommunity.com/supportforums/board/message?board.id=si_virus&message.id=42328 .

      I recommend you do so .

      P.S. And you should seriously consider "replacing" the increasingly vulnerable
      Adobe Reader with the slimmer Foxit Reader; I did so some months ago .
