I couldn't see how to do intrusion prevention adjustments in Chrome. To be clear, this isn't a chrome thing. It is not chrome that is stopping these sites from loading, it is kaspersky plus.
I am still seeing this issue with Kaspersky Plus saying 'visiting an untrusted website has been prevented'. I have the website in question in the Trusted URLs section of the safe browsing settings. How to I get kaspersky plus to actually pay attention to its own settings?
