spyware found: trojan.killAV

by dzdon / March 13, 2007 9:34 AM PDT

My AVG spyware just found this in my latest scan.

I went to quarantine it and it said it "cannot be quarantined b/c it is embedded in the archive...do I want to quarantine the whole file?"

it showed up at file c:\windows\I386\MMSSETUP.CAB/msmsgsin.exe
and was embedded in the file c:\programsfiles\messenger\msmsgsin.exe

I haven't had the response to a threat before....is that bad?? typical??

I chose "yes" to quarantine the whole file. Wasn't sure what to do.
When I saved the report it showed
trojan.killAV-->cleaned with backup (quarantined)

Anyone have thoughts on this?
Thanks,
dz

Looks like the Trojan is in your MSN Messenger.
by dawillie / March 13, 2007 9:59 AM PDT

I would

1. re-scan and quarantine and delete from the virus vault the Trojan n question.

2. Scan again to make sure you do not have it anywhere else, like Prefetch, system 32 or system restore folders.

3. Uninstall from start>settings>control panel> add/ remove> your Messenger.

4. Go to Program files and delete the Messenger folder and whatever is in it.

5. Re-install your messenger.

6. Re- scan to ensure it is not back.

What I would do......
by Marianna Schmudlach / March 13, 2007 11:38 AM PDT
In reply to: What is msmsgsin.exe?

is:

Upload the file (c:\programsfiles\messenger\msmsgsin.exe) to:

one of these scanners:

http://virusscan.jotti.org/

Virus Total Scanner

Virus.Org Rogue File Scanning Service

http://www.kaspersky.com/remoteviruschk.html

Could well be it is a FALSE POSITIVE ?

From AVG FREE forum:

If you suspect a file to be a false positive. Test the file at [virusscan.jotti.org] and if it is a false positive, archive (zip, arc, tar etc) the file using a password and email a copy to virus@grisoft.com with a brief description as well as the password you used to archive it with.

If it is a false positive , turn off hueristic scanning for the time being. When Grisoft adjusts the virus defintions you can turn it back on. If disabling the hueristics isn't enough you may have to disable the Resident Shield to test or email the file etc.

Could you tell me how to upload
by dzdon / March 13, 2007 12:44 PM PDT
In reply to: What I would do......

the file to be scanned?

I will start with that to see what the other scans turn out on it.

I also have a question about the archiving to send to Grisoft if it is a false positive...but that I suppose can wait until I try the other scans first!--Not sure what the zip, arc, tar are that's mentioned to archive.

Thanks for any help with the uploading question!

Uploading
by Marianna Schmudlach / March 13, 2007 3:18 PM PDT

First of all can you SEE the file mentioned on your computer??

As you get to Jotti's scan webpage - you see at the top:

File to upload & scan: and next to it: a browse button. Click on the browse button and look for the file on YOUR computer which should be scanned then click on the file - then click on submit - then you only have to wait on-line till you get the results.

That's all... but be patient Wink

.......

At the Virus Total page - look at the TOP ..... "select file" and then a "browse" button - click on it and as you find the file "in question" click on "send" and wait till you get the results.

Thanks for the suggestions
by dzdon / March 13, 2007 12:22 PM PDT

I will continue to look into this...

This may be an obvious or quite silly question, but what is messenger used for? Is it something I would have to open myself or is it used to support other applications? Just wondering...
Thanks again!

Messenger is disabled
by dzdon / March 13, 2007 1:43 PM PDT
In reply to: Windows Messenger...

When I went to the suggested link to disable I followed the steps, and I guess Messenger is already disabled--so found out.
The icon on the bottom tray has the little red x on it...
Is there a way to remove it from the tray if I don't use it?
Is that in the start up programs somewhere??

Reboot your computer - it shouldn't show up anymore.

Do I need to do anything with the ones I quarantined?
by dzdon / March 14, 2007 9:27 AM PDT

Is there any follow up I need to do with a false positive?
I am doing all my updates and rescanning...
Not sure if I should leave the False positive results in quarantine or remove them.
Thanks again for help.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
