Hi all,

I tried to install the ShrewSoft VPN client on a Win XP Pro 32bit. The
installation ended up with a bluescreen telling me, that there are problems
with a vfilter.sys. 

After a reboot I got some messages about unrecognized devices.
There is:
- Shrew Soft Miniport Filter #3
- Shrew Soft Miniport Filter #4
- Unknown device (Device Instance Id: ROOT\MFLT\0000)
All these devices cannot be uninstalled by the administrator.

I read the news:
and tried to uninstall all devices as listed in the post.

I also tried to uninstall the program. Uninstall processes well, but after a
reboot the above listed devices did appear again in the device manager.

It would be very nice, if anybody can give me a hint, how to uninstall these

Best regards

Alexander Maringer
