Could this be a false positive? Kuluoz.A

Recommended Posts

MS Security Essentials has several times over the past week detected TrojanDownloader:Win32/Kuluoz.A; however MWB has not, nor ESET. Security Essentials shows action tacken as REMOVED. But then the threat is detected again.

Can't find anything on this virus name in your forum. Treand Micro reports it's an Aliase for TROJ_KRYPTIK.LJC

I'm not sure if real theat or if I should proceed with your virus instruction, and greatly appreciate your direction.

Kind regards,

If you believe this is a new infection or one that should be detected by Malwarebytes, you can aways submit the file to the Research Center --> Right HERE

They will analyze the file and deem weather it should be added or not.

I don't believe as I have no clue if this is a new infection. That's why I am asking the experienced for their guidance/direction on this matter. I'm an office manager for a small non-profit that has zero tech support. I'm willing to do what the forum admin suggest. So hopefully they will reply to me. Thanks.

Hello Todostaff,

TrojanDownloader:Win32/Kuluoz.A is Microsoft's name/classification for a recently identified trojan. REF http://www.microsoft.com/security/portal/Threat/Encyclopedia/Entry.aspx?Name=TrojanDownloader%3aWin32%2fKuluoz.A

This threat is classified as a trojan downloader. A downloader trojan accesses remote websites in an attempt to download and install malicious or potentially unwanted software. Some downloader trojans target specific files on remote websites while others may target a specific URL that points to a website containing exploit code that may allow the site to automatically download and execute software or malicious code on vulnerable systems. This threat is detected by the Microsoft antivirus engine.

If any of your systems has this indication, disconnet it from the local network. And then follow-up to clean this system. If your organization has a recent backup of this system, take steps to restore it from a known good backup.
