Forums / Miscellaneous Discussions / Computer Trouble

I have a problem not related with the game, so I am thinking it should go here...
I bought a new computer, windows 8, touch screen, a good new computer. And it has been only 3 days, I have only visited some major sites like FB, Youtube, mails, and some news and spots portals, and VU of course.

So I have tried to stick to only trusted sites, but yesterday I got an error
Computer needs to restart, error BAD_POOL_CALLER
Anyone have any idea how that came? And what is it?

And how can I get that ,since I only visited these sites. I havent downloaded anything or watched movies or anything, it has only been 3 days.
I have Kaspersky Antivirus too.

Advice please.

I did Google that, but from there I did not really understand much
Like, how did it happen, why did that error come? From where?
What can I do to prevent that? Any ideas?

HotSpotShield is a VPN, and I guess it's outdated or is somehow incompatible with Windows 8... Either way, they say the fix is to remove it, or update it... whichever works for you I guess... if neither do, maybe you should call tech support.
