Hi gthotmail,
This is Mike from the Norton Authorized Support team.
First, I want to let you know that I do not interpret Log files. I provide support for Norton consumer products only.
The "mumawow,Flinf?" is a known virus that may have come through your system attached to another virus. The virus may keep reappearing for many reasons. If your Norton product does not contain the latest updates, which are downloaded and installed using LiveUpdate, and you have not completed a recent "Full System Scan," those can be the reasons why your computer is still infected.
In order to provide you with the proper instructions to resolve this issue, please let me know the following information:
1. What Norton product and what Version is installed on your computer?
2. What version of Windows are you using?
Please respond back to this post and let me know the answers, so that i can provide you with the correct steps to resolve this issue.
Thank you,
Mike
