Hello Been using Adguard for a while now and have had no issues , but after updating to 5.10.1190.6188 , IE 11 has been slow to load some pages and even crashes sometimes and has to restart. If Adguard is disabled, everything is fine again . Running Norton Internet security , but always have been and never had a problem before the latest update to Adguard . Windows 7 64 bit . no other security software. Thanks .
