Microsoft Firewall Client – ISATRAY.EXE

Isatray.exe installs as part of Microsoft's Firewall Client that installs with Microsoft Windows 98, Me, 2000 and XP as well as Microsoft's Internet Security and Acceleration Server 2000. This file itself is harmless.

Unfortunately, this file can be exploited by the Backdoor.Udps.10 trojan. This trojan gives a remote attacker access to your computer. By default it listens for incoming connections on ports 101 and 1700. The existence of the files udps.exe or isatray.exe may indicate a possible infection. More information and removal instructions can be found at http://securityresponse.symantec.com/avcenter/venc/data/backdoor.udps.10.html.
