In some security suites, some drivers are actually used by both components,
even though they may have originally been identified with just one of the products.
I am still working on how to reliably and consistently confirm such use for specific products.
As I said, I have not yet been able to confirm this supposition re F-Secure. These drivers may or may not be needed by the AV.
If they are not, the question remains - (What is happening to cause these drivers to fault, if the FW is not active.)
BUT... the test I suggested above may help rule out or prove that supposition.
RE: your question
If all else fails, disabling completely may be done by uninstalling, per my suggestion above.
Why make the same driver integral to both components? It is a matter of decreasing the footprint in your hard-drive I suppose.
But... I see other potential issues there too, thus my judgment that stand-alone products may serve better. YMMV.
Route44 should be able to help you more on this.
Sorry I don't have more time right now to fully chase this down.
What I have suggested will allow you to work directly on the problem solving.
You might also try your own research via Google, to see what you can learn about these drivers.
There are many reputable sites that provide file information. F-Secure may also have such information.
Just be careful to avoid sites that WOT flags as untrustworthy.
Some try to push "free downloads" that in the end cause you problems... which you then are offered the chance to "fix" - by buying their product.
(Rogueware!)
By the way... my review of your minidumps was not flagging the same drivers.
I am now trying to diagnose why Route44 and I were getting different results.
Diagnosing my own diagnostic tools is part of why I am not able to do more for you right now.
I just offered an observation, based upon what Route44 was finding in your reports.
Just re-read your post...
Are you saying that you have neither your Window Firewall, NOR your third party firewall enabled?
If so, that is an open door to a drive-by... Not recommended.
