Hi,

Last night I was on facebook and I received what appeared to be a legit email from a friend, with a video link on it. I of course clicked on the link and at that moment my Anti Virus program Webroot with AV caught two virus'

MAL/VidHtml-G
MAL/Encpk-KV

Webroot was able to immediately quarantine these two virus and I was able to delete them from my PC. I immediately ran a full scan of my PC and nothing was found. I then restarted my PC in safemode and did another Full Sweep, nothing was found. I checked the processes that were running on Task Manager and nothing out of the ordinary caught my attention. I don't seem to be having any issues. But when I went back to Webroot and looked at the logs, I notice this one log

WARNING Antivirus Engine for IFO Returned [WL] on [C:/Windows/NIRCMD.exe]

I did some searching around and I'm thinking that this may be a false positive but I'm not entirely sure.

Any suggestions or help is greatly appreciated.

Thank you.

Rich

My PC seems to be running normal:

If you don't see anything out of the ordinary, then my question is why do I see the below in the logs for Webroot:?

WARNING Antivirus Engine for IFO Returned [WL] on [C:/Windows/NIRCMD.exe]

Please note I did not run Webroot again as per your instructions.

Waiting for your reply.

Regards,

Rich

Hi rk1115
sorry about getting back late.
I don't see anything jumping out so let be sure and do the following in order.
FIRST:
Make sure Internet Explorer isn't open

Run hijackthis again. Hit None of the above,
Click Do a System Scan Only.
Put a Check in the box on the left side on these: (Not to worry if not there)

O2 - BHO: (no name) - MRI_DISABLED - (no file)
O2 - BHO: (no name) - {02478D38-C3F9-4efb-9B51-7695ECA05670} - (no file)
O13 - Gopher Prefix:


Close ALL windows and browsers except HijackThis and click Fix checked
Then reboot

NEXT:
After reboot

Do This

Using Internet Explorer, please do a Kaspersky online scan] This scan takes about 60 minutes to complete.

GET IT HERE:


Answer Yes, when prompted to install an ActiveX component.
The program will then begin downloading the latest definition files.
Once the files have been downloaded click on NEXT
Locate the Scan Settings button & configure as follows:
Scan using the following Anti-Virus database:
[/b]Extended[/b]
Scan Options:
Scan Archives
Scan Mail Bases
Click OK & have it scan My Computer
Once the scan is complete, it will provide a report if your system is infected. It does not provide an option to clean/disinfect. We only require a report from it.



Click the Save as Text button to save the file to your desktop and post it in your next reply along with a fresh HijackThis log

* Turn off the real time scanner of any existing antivirus program while performing the online scan

The NirCmd.exe noted as a problem in many scans , must be a tool or file from tools that you have previously run for security purposes.

Is not a issue but okay to delete.
you can go to C:/Windows/NIRCMD.exe
delete just the file in RED
good luck mschroe919

Nothing was found when I ran the Kaspersky online scan, and it didn't create any logs.

I have deleted the :/Windows/NIRCMD.exe.

I then ran another sweep with Webroot, and the warning about NIRCMD no longer appeard.

I think everything is good now and this can be closed. If you agree, I want to thank you for your help.

Regards,

Rich
