Shortcut Virus Removal

Created: 03 Jun 2013 | 4 comments

I am using symantec endpoint protection, recently my external hard drive got compromised by a virus, which hides the original folder and creates their shortcuts. I can see that its slowly affecting 'My Documents' folder too in my system.

In my hard drive there is this unknown folder 'c2c2' is getting created with 2 .js files in it. I believe the autorun.inf file is infected and is re-activating the virus again, even after deleting the folder.

I tried scanning my hard drive using Norton Endpoint, but of no use. Can anyone please suggest me a solution as i cannot afford to format my external hard drive.

Hello,

Are running the SEP 12.1 client with latest definitions and carry all the latest Microsoft updates and security patches on the machine?

Run a scan in safe mode with networking to remove the virus.

Could you zip each of the folders and submit the zip files (without password) to the Symantec Security Response Team on : 

https://submit.symantec.com/websubmit/essential.cgi

We also offer a self-service site to analyze files, at http://www.threatexpert.com, which can give you more information on the files you submit to it.

In your case, it is also advisable to follow few important steps:

1) Make sure all these machines are Patched with ALL Latest MS security patches and service packs.

2) Make sure the machines are installed with the Latest Symantec virus definitions.

3) Disable the Autorun Feature on the machine via GPO. http://support.microsoft.com/kb/967715

4) Disable System Restore before you do this as the virus also creates entries in the System Restore Points store volumes.
