Been trying all week to solve this problem. Cannot update Windows updates or load down fixes or update Microsoft security essentials. Have installed AVG and threats were removed and all was back to normal for a day. Then did fix suggested on Microsoft forum which worked for a little while. Then installed Malwarebytes software which quarantined 4 threats and all worked for a day. At my wits end. Have the run the software this site suggested to create logs. Any ideas?
