Thanks for your answer to my question of 13/11/06.
When I went to the AVG Virus Vault it showed all the dates when the Trojan Horse was identified. Do I press the second button at the top which says ''Press button to delete selected objects from the AVG Virus Vault, a safe virus quarantine''.
I am not sure and scared to do anything with these objects - do I empty the Vault - is this safe?
Yes, delete them all from the vault. I know it all sounds a bit scary but it is very unlikely that any of the files in there are important. If you are unsure, you could always do a restore point on your PC first, but as i say, they have probably been in there a while and your pc is running fine with them out of the way.
