Bad pool header and blue screen after install Bitdefender IS

[Exterminator]

After I had experienced a blue screen problem, I used norton removal tool and then reinstall bitdefender.
Until now, I have not experienced a blue screen. But, I need to test further.

I would give BIS a chance now that the BSOD problem has been taken care of.As long as you have not purchased a license you can always give another suite a try later on if your not happy with Bitdefender.Sometimes different AV's/Security Suites run better than others depending on your machine,OS & installed programs.Bitdefender offers good protection buggy or not.Personally I have found ESET,Kaspersky & EIS to perform the best.Only problem with EIS is it's conflict with Virtual Box.If you don't use VB then it's all good.However there is a back and forth blame game between the two and unfortunately no resolution.
