It is used by ZoneAlarm. I have gotten BSOD from 394160/397312 bytes. I hope they figure out the problem.

It is a Zone Alarm file. To remove it: Device Manager, View Show hidden devices, Non plug and play drivers Right Click on vsdatant.sys disable. Uninstall Zone Alarm - then Reinstall if you want.

This file is also used with Cisco VPN Client, if you have stateful firewall enabled. Causes a BSOD with F-Secures firewall.

Indeed it is also used by Cisco VPN client, the statefull firewall part. Caused problems on my machine. Disabling service vsdatant in regedit solved problems concerning connecting to tcp port 80.. (Which makes you wonder why it wants to hijack this port?)

vdsdatant causes windows stop blue screens less than 2 minutes after booting the laptop, there was no solution from dell but uninstalling zonealarm security suite in windows save mode solved the problem!

Truevector device driver is necessary for Zonealarm (firewall). Do not remove unless have a replacement ready. (Reminder: check if something is trying to masquerade as vsdatant.sys)

I uninstalled Zone Alarm (free) and installed Zone Alarm Pro and now this appears in RegSeeker as an orphan to be deleted.

Vsdatant.sys is also a legit component of Cisco VPN Client software. I believe that they use Zone Alarm soft as part of their stateful firewall.

It caused my system to repeatedly reboot. It should have been removed when I uninstalled ZA. Therefore, I think it's a malicious leftover file.

Die Datei hält unter c:\windows\internet logs\ die Dateien fwdbglog.txt und fwpktlog.txt geöffnet, außerdem c:\windows\system32\vsconfig.xml. Wer bei einer unsauberen ZoneAlarm-Deinstallation den Treiber noch im System hat, wird Probleme mit einer Neuinstallation bekommen

I confirm its related to Zone Alarm. It gave me crashes (blue screen of death) when using IExplorer. - system: XP SP2, ZoneAlarm non-commercial, updated in August 2005. Problem actually started to appear after update. If file is removed, ZA stops working, obviously.
