Nasty slow AV hiding itself by intercepting the DLL loader and slowing all your programs by reloading every DLL on every call! How can you get any work done at that rate? You need a Xeon to get an Atom's worth of work done. ;^< If you don't already have one, you could request a workstation with that CPU, 64GB max speed RAM, and giant SSD to counteract the impact of the AV, or request they come up with an alternative approach. ;^> If you can't provide a full cygcheck, at least cygcheck and ldd cygwin1.dll and graph and provide the list of DLLs invoked, which may show interceptions, and may sometimes be avoided by adjusting Cygwin PATH; e.g.: $ for e in /bin/cygwin1.dll /bin/graph; do for p in /bin/cygcheck /bin/ldd; do echo \$ $p $e; $p $e; done; done | sed 's!^\t!!;s!\\!/!g;s!/cygdrive/c/!c:/!;s!C:/cygwin/!/!' $ /bin/cygcheck /bin/cygwin1.dll /bin/cygwin1.dll C:/Windows/system32/KERNEL32.dll C:/Windows/system32/ntdll.dll C:/Windows/system32/KERNELBASE.dll $ /bin/ldd /bin/cygwin1.dll ntdll.dll => c:/Windows/SYSTEM32/ntdll.dll (0x7ffb78b40000) KERNEL32.DLL => c:/Windows/System32/KERNEL32.DLL (0x7ffb77c90000) KERNELBASE.dll => c:/Windows/System32/KERNELBASE.dll (0x7ffb76940000) advapi32.dll => c:/Windows/System32/advapi32.dll (0x7ffb76d50000) msvcrt.dll => c:/Windows/System32/msvcrt.dll (0x7ffb78380000) sechost.dll => c:/Windows/System32/sechost.dll (0x7ffb77bf0000) RPCRT4.dll => c:/Windows/System32/RPCRT4.dll (0x7ffb78760000) CRYPTBASE.DLL => c:/Windows/SYSTEM32/CRYPTBASE.DLL (0x7ffb753d0000) bcryptPrimitives.dll => c:/Windows/System32/bcryptPrimitives.dll (0x7ffb768c0000) $ /bin/cygcheck /bin/graph /bin/graph.exe /bin/cygplot-2.dll /bin/cygwin1.dll C:/Windows/system32/KERNEL32.dll C:/Windows/system32/ntdll.dll C:/Windows/system32/KERNELBASE.dll /bin/cygpng16-16.dll /bin/cygz.dll /bin/cygX11-6.dll /bin/cygxcb-1.dll /bin/cygXau-6.dll /bin/cygXdmcp-6.dll /bin/cygXaw-7.dll /bin/cygXext-6.dll /bin/cyggcc_s-seh-1.dll /bin/cygXmu-6.dll /bin/cygXt-6.dll /bin/cygICE-6.dll /bin/cygSM-6.dll /bin/cyguuid-1.dll /bin/cygintl-8.dll /bin/cygiconv-2.dll /bin/cygXpm-4.dll $ /bin/ldd /bin/graph ntdll.dll => c:/Windows/SYSTEM32/ntdll.dll (0x7ffb78b40000) KERNEL32.DLL => c:/Windows/System32/KERNEL32.DLL (0x7ffb77c90000) KERNELBASE.dll => c:/Windows/System32/KERNELBASE.dll (0x7ffb76940000) cygplot-2.dll => /usr/bin/cygplot-2.dll (0x3bb760000) cygwin1.dll => /usr/bin/cygwin1.dll (0x180040000) cygpng16-16.dll => /usr/bin/cygpng16-16.dll (0x3bb610000) cygXext-6.dll => /usr/bin/cygXext-6.dll (0x3eb640000) cygXaw-7.dll => /usr/bin/cygXaw-7.dll (0x3eb710000) cygXt-6.dll => /usr/bin/cygXt-6.dll (0x3eb220000) cygX11-6.dll => /usr/bin/cygX11-6.dll (0x3eb7b0000) cygz.dll => /usr/bin/cygz.dll (0x3b2da0000) cyggcc_s-seh-1.dll => /usr/bin/cyggcc_s-seh-1.dll (0x3dd6b0000) cygXmu-6.dll => /usr/bin/cygXmu-6.dll (0x3eb300000) cygXpm-4.dll => /usr/bin/cygXpm-4.dll (0x3eb2d0000) cygICE-6.dll => /usr/bin/cygICE-6.dll (0x3ffc80000) cygSM-6.dll => /usr/bin/cygSM-6.dll (0x3ebb40000) cygxcb-1.dll => /usr/bin/cygxcb-1.dll (0x3b2f90000) cyguuid-1.dll => /usr/bin/cyguuid-1.dll (0x3b73e0000) cygXau-6.dll => /usr/bin/cygXau-6.dll (0x3eb780000) cygXdmcp-6.dll => /usr/bin/cygXdmcp-6.dll (0x3eb660000) cygintl-8.dll => /usr/bin/cygintl-8.dll (0x3c2560000) cygX11-6.dll => /usr/bin/cygX11-6.dll (0xcd0000) cygiconv-2.dll => /usr/bin/cygiconv-2.dll (0x3d6e00000) -- Take care.
