Hi all,

I have Microsoft security essentials antivirus to protect my system. I set to scan every week by default. By mistake I clicked the pop up advertisement while watching a video. I got little bit scared whether it might download some virus, so immediately I started to run the antivirus. But I got this error message, ‘system is connected to Wi-Fi’. Why I am getting this error? Please suggest me some solutions. Thanks.
