|I had a similar issue on my windows 8.1 laptop|
I have an Aspire V3 with 8gb ddr memory and is normally very quick.
Bullguard slowed it up completely at start up.
I disabled auto update on start up and selected warn me if settings are old after 7 days.
It now runs normal.
Its a strange issue as I do not have this with my Vista desktop machine.
On my XP lap top I have now uninstalled Bullguard as it was giving far too many issues with my programmes on there. I run a free Commodo on that machine
