Infection Blocked Notification Each time I turn My Pc On - Please Help

[REDACTED]

Hi Guys... I need a bit of help here... Im not a Techy guy so please bear with me...

Pretty Much each time I log my Pc on I get a Threat Blocked Notification from Avast... The URL it comes from varies but sometimes is ones which sound familiar (i.e. I have seen the name before). Here Is an example of One : http://gyazo.com/831617861b01a246572028a7441721f6

I have done scans Using Avast, Malwarebytes, CC cleaner, & MSE but they never find anything...

The threat detection is a recurring notification & is therefore making me wary...

Any help would be great

Thanks

Yak
