One of my application calls EnumPrinter API. It hangs on
a PC and exact hanging point is that EnumPrinter call.
Namely, EnumPrinter called and it doesn't return.

I checked the call stack of the thread when it hanged and
found a call via autochk.exe!0xXX.
Call stack looked something like :
- - - -
ntkrnlpa.exe!Something+0xXX
..
ntdll.dll!Something+0xXX
autochk.exe+0xXX
...
MyApp.exe!EnumPrinter+0xXX
- - - -
Why should autochk.exe be there? What does it do?
Could it be an virus?

Thanx.
