Sporadic, yet frequent, BSODs on Vista -- zipped dmp files attached

[BSODEFGH]

Basically the title says it all.... It's been driving me nuts! I'm attaching a few zipped dmp files. It happens when I expect it the least. It's on my Dell XPS with 12 GB memory Vista 64. Any help will be highly appreciated! Thanks.

Your issue is with the driver vfilter.sys which which is a ShrewSoft IM Filter Driver - ShrewSoft Virtual Network Adapter by ShrewSoft.

oh wow... Thanks! That's the only VPN client that works on Vista 64 for me to connect to work... but who cares! This is driving me crazy..... Funny thing is I'm never using the VPN when the reboot happens... In fact I have not used it in a long time...

Do you think if I uninstall it, I'll be OK? What can I do?

Uninstall. It most likely has a few drivers that engage at the load time causing issues.
