I'm running Zonealarm extreme security v.9.3.014
and it recently detected a false-positive for a trojan called Backdoor.Win32.Rbot.amhq when scanning the installation package 'Altdesk.1.9.1_English.exe' downloaded from Astonshell's 'Altdesk' product page.

Kaspersky's Virus Removal tool 2010 v. also detects the same trojan when scanning the file. I sent the file to the Kaspersky lab & they've confirmed that its a false-positive.
