@ the request of Mikaelrask, I am posting my issue here with my logs with the problem similar to the OP in THIS thread.
About three weeks ago I began to have the hxxp://request.safersearch threat detected popup three in a row.
So I uninstalled the Youtube add on in Firefox because I read for another person that was the problem… Didn’t work for me.
So, I ran Mbam, nothing was found. I am running Firefox 38.0.5 (now running the newest release 41.0.2) and Avast 2014.9.0.2018 with updated definitions, and haven’t had an issue until as previously mentioned about three weeks ago now. The problem duplicates both sandboxed & unsandboxed. BUT I think this issue only presents itself on the limited user account as I have not seen the popup(s) in the Administrative account when opening Firefox.
I have ran the programs, and have attached the logs for help.
To note, I saw Adw when downloading the other programs and grabbed that for good measure too but wasn’t sure what was safe to delete and can attach that when you need it.
The fixlog is now attached, but a few questions just to make sure I didn’t inadvertently make your job more difficult:
1.) Since the error occurs only in the limited user profile, do I need to rerun FRST under the limited user acct. and then obtain a new fixlist txt or did the run under the admin account do enough work for all the profiles?
2.) Also I ran the FRST scan in Safe mode under the admin account (as noted in the log), does that make a difference in how effective the cleanup tool is?
