Java/TrojanDownloader

Hello,

I just did a scan of my C:/ drive with the latest virus definitions (4788 ) and it found 1 threat:

C:\Documents and Settings\User\Application Data\Sun\Java\Deployment\cache\6.0\47\4934abef-1d67c050 » ZIP » ________vload.class - a variant of Java/TrojanDownloader.Agent.NAC trojan

However, it is not in quarantine and was not cleaned. I think I may have found the file but it hasn't been motified since November. There are two files with the exact same name (both called: 4934abef-1d67c050). One is classified as a file, the other has a file extension of .idx

What is this threat and what should I do?

Thanks,

Mark.

 

Perhaps you only performed a scan without cleaning? Otherwise you should have been asked to choose an action to perform after the scan had been completed.

 

Hi Marcos,

Thanks for your fast reply. I did the scan again and it found the same threat but this time it put it into quarantine. I didn't change any settings- they have always been on default. The scan took unusually long (1h33m) instead of 55m-1h. Any idea why? Am I safe now?

Also, is there anyway of knowing when you are infected? (Or where the infection could have come from?) Because there was no performance loss, pop-ups, or unusual processes in task manager.

Thanks,

Mark
