Rok Posted December 11, 2019 Share Posted December 11, 2019 I had responsive internet connectivity until I ran Kerish Doctor 2019 on my notebook. Now, after the Kerish finished its optimization job, the internet does not connecti.e neither browser connects to any site nor download managers like IDM are able to download any file. I have checked most settings, but to no avail. Can anyone spill the beans, please I don't want to restore or refresh notebook system. Link to comment Share on other sites More sharing options...
Israeli_Eagle Posted December 11, 2019 Share Posted December 11, 2019 Maybe try a System Restore!! And NEVER let this 'doctor' into your house. Link to comment Share on other sites More sharing options...

Marcus Thunder Posted December 11, 2019 Share Posted December 11, 2019 Did you try simple solutions before trying on troubleshooting. Can't you undo optimization in kerish doctor, usually all optimization apss have an option to undo what they have done & they create restore points. Try retarting pc, exiting kerish, maybe disconnecting, deleting your internet connection & reconnecting again. Uninstalling kerish.... Try connecting using different method as wifi instead of LAN Cable... Link to comment Share on other sites More sharing options...
scarabou Posted December 11, 2019 Share Posted December 11, 2019 I have been running Kerish Doctor for a couple of years with no problems at all. Try to use the "Rollback Changes" utility in Tools > Work with Kerish Doctor 2019 > Rollback Changes. Link to comment Share on other sites More sharing options...

Rok, Try this, type cmd (run as admin) netsh winsock reset and press Enter. Restart your PC Done Link to comment Share on other sites More sharing options...
DLord Posted December 11, 2019 Share Posted December 11, 2019 Control Panel > Internet Options > Security : Not above Medium-high Control Panel > Internet Options > Connections > LAN Settings > Nothing checked Then OK and Apply. This is the simplest check to be done if you lose internet connection in Windows OS. Link to comment Share on other sites More sharing options...
Rok Posted December 12, 2019 Author Share Posted December 12, 2019 Hi all, Thanks for taking time and suggesting remedies. Soon, after writing here, I just did the changes 'rollback' and the Net is back to life. I am now trying to see what changes this Doctor has made that resulted in blocked internet.
