I have had a problem for a while : the hard drive led blinks every two seconds when no program is running :


My config : windows 7 sp1  x64 + avast 8.0.1489.


Avast, Malwarebyte, TDSSkiller, GMER found nothing.

There is no IO on the hard drive visible in process explorer.

But catchme found a kernel modification :


detected NTDLL code modification:
ZwEnumerateKey 0 != 47, ZwQueryKey 0 != 19, ZwOpenKey 0 != 15, ZwClose 0 != 12, ZwEnumerateValueKey 0 != 16, ZwQueryValueKey 0 != 20, ZwOpenFile 0 != 48, ZwQueryDirectoryFile 0 != 50, ZwQuerySystemInformation 0 != 51Initialization error


Anyone has an idea ?
