A couple days ago when AVG updated the signitures, it located MKAR.K in 2
files on my system.Both infected files were Electroic Arts games.
C:\program files\EA Games\MOHAA\Ereg MOHAAB\Medal of honor Allied Assault
Breakthrough_EZ.exe
C:\Program Files\EA Games\Command & Conquer Generals Zero Hour\support
\Command and Conquer Generals Zero Hour_EZ.exe

I'm a bit concerned because I didn't find MKAR.K anywere else. Could
someone tell me how MKAR.K typically infects a computer. Generally I'm
pretty careful about junk coming in to my computer. I have ZoneAlarmPro
running also.

Might be a flase positive. Send the executables to grisoft for
analysis. They should rectify these if they are inded falsly
identified as virus.

I saw a post on this infector recently and found no real information on it.

W32/Mkar.gen -- http://vil.nai.com/vil/content/v_126622.htm
W32/Mkar.a -- http://vil.nai.com/vil/content/v_130636.htm

They were also using AVG. Could it be a False Poistive ?

Please submit the two EA Games executables to Virus Total --
http://www.virustotal.com/flash/index_en.html
The submission will then be tested against several different AV vendor's scanners.

Another way to submit is to send the suspect file to the following email address
scan<at>virustotal.com
{ replace <at> with @ } with only the word SCAN as the subject.

Please post back the EXACT results.

Ian:

You beat me to it ;-)

I suggested Virus Total so it will be tested against several AV vendors.

Thanks everybody for the quick reply. It sounds like false positives
from the posts and the links. I'm trying to submit the files, but AVG
moved them to the virus vault, and I don't know where that is. I'm
looking and I'll submit them (when I find them) and see.

I guess this is a common problem with AVG and EA games.

Kevin Renn

lso.
 
Well, the results are in. It's a false positive (unless AVG is right and
everyone else is wrong).

It was too much of a coincidence that two EA Games would be flagged and not a file in the
OS.

I'm glad it was a False Positive declaration but now Grisoft needs to know.

Interesting how AVG doesn't flag it on Virus Total..

"AVG 718 02.21.2005 no virus found"

What is the version of AVG and the definitions you are using ?

Program Version:7.0.300 (Free Version)
Signiture Version 266.4.0 (2-22-05) (it updated when I started it up
today so I don't know the version that hit on the EA files was)
 
I contacted the other poster in another News Group and he indicated ...

"Yep, it was in an EA game"
