Check your computer for the following conditions:

• In the folder [C:\WINDOWS\system32\drivers\] the file “DKbFltr.sys” shows 0kb in size.
• In the 64-bit folder [C:\WINDOWS\sysWOW64\drivers\], there is a “DKbFltr.sys” and its size is ~25kb, and it is properly signed (view its properties)

If this is the case, delete the 0kb file C:\WINDOWS\system32\drivers\DKbFltr.sys and the GuardedID® Status will return to normal. Acer laptops with Windows 7 64-bit are likely to have this problem.
