vsdatant.sys causes Blue Screen of Death: System WinXP Pro with latest updates, Spybot Search & Destroy Antispyware, Lavasoft Adaware, GDATA Antivirus.
After using numerous versions of Zonealarm firewall under Win98 and now WinXP Pro I started to get blue screens of death during every shutdown and frequently also during normal operation about 3 months ago. After installing new drivers for all hardware etc, loosing many hours, I finally analysed memory.dmp with the offline debugging tool of Microsoft. It pointed to vsdatant.sys as the culprit. I deinstalled Zonealarm firewall and immediately all problems were gone. I downloaded the lates version of Zonealarm. Whenever I start to install it, I immediately get a Blue Screen of Death, even if I quit GDATA Antivirus, Spybot Search Destroy before installing. I have several other machines with quite the same software, no problem with Zonealarm on them. Any idea what I can do. I am familiar with zonealarm and content with the functions, so I would rather not change my firewall.
