Hello experts,
I have Microsoft security essential firewall to protect my system from virus. This was working well and good, I am using this for more than a month. Today when I try to run the quick scan I am getting this error message. I recently updated the firewall version online. Is there any problem with the log file after the update? Please help. Thanks.
