MsvcpP90.dll is one of the C run-time libraries that ships with
Microsoft Visual Studio 2008:

    http://msdn.microsoft.com/en-us/library/abx4dbyh.aspx

You can also get them as part of a separate redistributable package,
e.g. vcredist_x86.exe.

Does SuperAntiSpyware provide digest or checksum information for the
files it scans? The MD5, SHA1, and RMD160 hashes for the copy of
msvcp90.dll we shipped with 1.2.0 are:

MD5(msvcp90.dll)= 871f979d70414c900b35e56222932daf
SHA1(msvcp90.dll)= dd683e4ad54cab6ba1c7b3ce9c0925db0e1d0e66
RIPEMD160(msvcp90.dll)= 95f2bc0902409ec68e276bd742d54369556f0f1a

The DLL file version is 9.0.30729.1. It was copied from Microsoft Visual
Studio 2008 SP1's "redist" directory. I checked the hashes above with
two other systems here, and they all match.
