Trojan.inject.ia =>no Action Possible!

Hi there!

I found a trojan infection in our friends' PC. They called me to help them a bit, since their PC stopped responding. I've run an online scan with BD since I consider it to be the best AV tool out there.

It found the trojan "Trojan.inject.ia". I've tried deleting it, renaming it, changing the .dll into .mov and then I tried to archive it with Winrar and deleting it, but no chance. It doesn't work...

Here's the link to the report created by AVIS: http://forum.bitdefender.com/index.php?sho...adeux&st=20

I've already submitted the file to MCU.

Thanks for your help.

Have you tried disabling System Restore before trying to remove the Trojan? Many trojans and worms makes sure to infect the System Restore files so after a successfull removal they simply restore themself. Disabling System Restore deletes all restore points on the computer.

Hi,

i`ve been infected with trojan.inject.ia too!

no attempt to delete it or the like works for me.

unfortunately my log file is german so i think you guys should have quite a few problems understanding it.

Is there any news on this problem?

Hopefully

Have you tried running BD in safe mode - it is possible that you need to be in safemode to get rid?

How about getting Malwarebytes Anti Malware (it's free) updating it to the latest update and then doing a full scan in safe mode.

In addition to BD I have Malwarebytes Anti Malware and Win Patrol .. both free. They all do a good job. Zone Alarm Pro v 7.4 is the firewall.

This is an injector, which means that it will inject its code into one or more processes. In this case, the trojan may have launched svchost into execution, and basically, overwrote the original code with its own. This way, the file remains clean, only its memory image gets infected. However, to make sure and remove any doubt, please attach c:\windows\system32\svchost.exe in a password protected zip/rar archive (using the password infected).

Best regards!

Please pack the file(s) in an archive, protected with the password infected.

Upload it on www.rapidshare.com or other server and leave here the download link.
