F-secure: a resource hog?

Hi

I am running F-secure on one of my computers and it is SOOOOO slow to start due to fssm32.exe belonging to F-secure.

Then I search a bit and find that F-secure are aware of this problem

http://support.f-secure.com/enu/corporate/supportissue/av-cs/usage/usage-issue-2004012000.shtml

they recommend to stop WFP (Windows File Protection), without mentioning anything about if F-secure replaces that functionality or what happens the day I uninstall it, thus I refuse to do that (in email from the support they say F-secure do replace the WFP functionality).

Did you guys have similar problems with F-secure, or is this some bad combination of my hardware and that program?
