I hope this is the right section of the board for this query.
I have been trying to get rid of Trojan-Downloader.Win32.Adload.jm for the past few days but it keeps coming back. On startup ZA reports that the trojan has been quarantined and is linked to a file tcinstall.exe on the desktop. Tcinstall never appears on the desktop - presumably because ZA has picked it up. I always delete the trojan but when I start up it goes through the same process. I have System Restore disabled and have checked the startup programs in the System Information but nothing indicates what could be installing this trojan.
