just to share a symptom on this office pc, AVG & kapasky couldnt detect it
windows7 i3 3120, 4gb ram no ssd
quite exactly 50% cpu is used on this virus when boot, (some times 4 threads at 50% or 2 threads at 100%)
its only found in resource monitor and not on task manager/ msconfig
it renames itself to another name , like hd audio / intel,,,
not going to fix it coz i dont care
