BSOD windows 7 x64; 3x this week; help with analysis

I've had three bsod this week. I only have one dmp file in minidump and that's attached.

Monday, April 12, visual studio 2010 was released and I installed it. The crashes started after that but of course there is not certain connection at this time. I crashed Monday, Tuesday, and Thursday (today) one time each. The first two bsod visual studio 2010 was loaded; today it was not; only apps I'd stated were firefox 3.6.3 and zimbra desktop (an email client). Today I had just clicked on a tab in firefox when the bsod took place. That might have been true the other times but I'm not sure.

This pc was built by myself a month ago; and it's the first 64 bit os I've spent any real time with.

Anyways I hope someone can provide a clue or two re what might be amiss from the dmp.

This crash was probably caused by your vfilter.sys, which is part of your VPN. I would uninstall it to test.

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 0000000000000000, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, bitfield :
    bit 0 : value 0 = read operation, 1 = write operation
    bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)

I'm curious how you know that vfilter is part of my vpn? I'm sure that you're right, just curious how you know that.

Also, the vpn was not running when the last bsod took place; nor had it been. I forgot to mention that the pc had been rebooted just 15 min before the bsod. Could vfilter.sys be involved when it had not been run during that session? the vpn does not start on boot or anything like that.
