I have a HP 15F009wm Notebook Pc. Running Win 10 64bit.
So far we have been able to determine it is not data corruption.
My resident AV/Windows Defender and Malwarebytes Premium both the scanner and the browser protector. None have found any issue so far. I have also ran FRST, Rkill, and eset online scan nothing found.
One thing of note FRST stalled for about 15 seconds first time I ever saw it do that. I have the logs when needed. I tried to run 2 rootkit tools [just in case] Reveal and GMER. Reveal is 32 bit only and kicked me out.
GMER tried to run, at first I would get a pop up saying something else was already running but I waited a few seconds and the pop up disappeared and GMER showed csr something with 3 threads running.
I tried to run the scan anyway and it ran for a few seconds then a window popped up saying windows had to shut down, collected some info and rebooted the machine.
I tried running GMER 3 times same results.
Should I try other specific tools. While we all run them on our own I know better than try to fix anything without direction.
