Hello. New here. I recently notice that when I go check my yahoo email there seems to be popup about norton antivirus. Sometimes it'll try to open the window but it closes itself, and repeat. So it clicks like crazy. Sometimes it'll totally overwhelm Iexplorer and I have to force shutdown. So I used an online scanner and one of the files found to be fishy. So I try to delete it but it would not let me delete. I try to be cunning and change the name slightly in hope to let me delete. But then it saved it's changed name and created another copy in the same directory. In the windows task manager it uses 29,750k of mem usage. So I suspect that this is not a good one. The file is located at "C://windows/msagent/wmsdoc.exe" Please help. Thank you in advance.
