To be more precise: The Trojan found at an adhoc scan by Bitdefender: Rightclick Appdata /Roaming / Thunderbird /Profiles/ :"scan with Bitdefender" I can´t supply the log as the OS was replaced with a several days old image that was clean. There was no other email traffic except fractint on my multifrac account, I suggest that the administrator performs a scan of the archives. Petta
