My PC's been infected with the download.ject trojan.

Norton has quarantined it and I've downloaded the Microsoft tool for removing it. The MS tool declared my PC clean and I've manually checked the registry, which seems to be okay, BUT Norton can't clean the quarantined file.

Should I just delete it???

There doesn't seem to be any information on what to do with the initial file which is downloaded.

 

If Norton had captured it, you have not been infected. It tells you it has not been successful in deleting it but you have the ability to quarantine it... do so.

When you have chosen to quarantine it, it is quite safe, you can periodically purge all files in that folder when you fancy .

 

It's a trojan, you can only delete trojans.
