Hi, I am having problems with my laptop. Occasionally it freezes and I can't do anything (Not even ctrl+alt+del). The same thing happened a moment ago, but this time the screen went black and showed a message:

'Logon process has failed to create the security options dialogue'
'failure - security options'

This is possibly coincidental, as I am often surfing the internet, but the freezing usually occurs when I have Firefox open. It has only been happening for the last few days.

Thanks

What are you doing in firefox when it freezes up?

Do you have any add-ons?

Watching video clips on youtube.com.

I have several add ons- Adblock plus, British dictionary (I might delete this, I've turned off the spell check for FF), java console versions 6.0.22, 6.0.23, 6.0.24 (do I need all these, or just the newest one?), Mcafee site advisor, new tab homepage

Although I'm not certain it is this causing freezing, it's frozen in other situations once or twice I think.

Have you made sure that all your drivers are updated such as video card drivers?

Not in a while, which ones should I update (besides the video card?)

Sorry for the late reply, I checked out the Intel site and it told me all my drivers were up to date (graphics etc.) except the wifi and wireless drivers. I tried to download the newest versions, but my laptop froze again...

This time I was using Chrome, not firefox

Also today when I tried to start in safe mode, it froze when loading windows files

Sorry for very late reply, but I THINK I've solved it- Mcafee internet security seemed to be the cause of the problem. Every time I tried to update it, my computer froze. The random freezes were possible caused by the program due to the automatic updates- every time it tried to update (without me knowing), it would just freeze. At one point it even caused a blue screen.

I went onto the mcafee website and downloaded the latest update manually. When I restarted, the computer seemed to be fine

Thanks for your help!

I just did a full scan with Mcafee (150000 files scanned) and it found nothing. Will also use malwarebytes to do a scan later
