Hello PDI, thanks for helping
Unfortunately i did not find any trace in Autoruns related to some "Thtise" or "8C53723358EF" entry...
maybe i can enclose the saved file from Autoruns if that helps.
I did find entries in regedit however
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache
under 2 different folders "Tasks", "Tree"
Not sure this helps... i have no idea what this file is
Thanks
