I believe i have found a possible new variant of ransomware. on the 10th of July i had tried to install a game from perfect world the game required me to download arc that is similar to steam. arc downloaded successfully but had started to slow down my windows 7 Toshiba laptop.right away. i then removed the program. when i went to restart my computer updates were installing so i let them install. after the restart however is when i got a black screen telling me :
Atheros PCIE controller V 18.104.22.168(12-15-09)
check cable connection
PXE-MOF: exiting Intel PXE Rom
no bootable device-- insert boot disk and press any key.
I have created a boot disc and tried to repair windows 7 to no avail. no operating system shows when the repair module is running and trying to find my OS. start up repair fails and has told me it cannot repair my OS.
I have run chkdsk to in the system tools and it has found these 2 files ngenro`1.dat,ngenrootstorelock.dat and replaced them.
my operating system is windows 7 home premium. my computer is a toshiba l655 s5146.
thanks for any help ahead that you may give ahead of time.
