Hi all ... im getting this message saying an intrusion attemp blocked etc .
It says intrusion attemp by marks-dell-xps was blocked ...... this is my computer so why would it block my own machine ???
And what on earth is " pornotube914.com " .... this machine has never been on any site like that 
I know i can stop this alert and tell it not to tell me about it again but im annoyed by this .
I have done a full scan with norton 360 v3 , superantispyware and malwarebytes and found nothing
Please help .........
