Blocked because of IPS attack

Hello all,


So all the sudden I cannot access the internet. I get the following message:


Blocked because of IPS attack

An attack was detected, originating from your system. Please contact the system administrator.


See attached screenshot.


Tried searching online but didnt find any clear information on how to fix this.


Anyone have any ideas where to start?


Thanks in advance,

J

Just ran a scan using Malwarebytes software (had to download on another computer and copy over since affected computer is blocked from the internet) The scan came back clean, no issues.


Rebooted the the computer in Safe-Mode and still have the same issue.


Not sure how / why this would be a scam? since there are no options to resolve the problem...doesnt seem to be a scam.


Just seems that all internet traffic is somehow being blocked...even in Safe-Mode.

Note that this is IPS, not ISP. It could be an “Intrusion Protection System” on your router. You could try restarting your router.


If that doesn’t work, or perhaps even it it it does, try running EtreCheckPro. EtreCheckPro is a diagnostic program I wrote to help show what might be causing problems like this. Download EtreCheckPro from https://www.etrecheck.com and run it. Create a new reply and use the "Notes" tool below to add your EtreCheck report.
