Hello
During my last scan AVG detected the JS/Downloader.Agent trojan.
Examining the virus vault I found it there, meaning that it was detected and, eventually, eliminated.
I tried to delete it from the vault as this is a very dangerous malware.
Was not able to get rid of it.
Question: Am I safe and can leave this trojan in the vault for good?
Or, should I delete it? if so how?
Many thanks in advance
Tom
