Run and then copy and paste each line below hitting after each
one.
regsvr32 Dssenh.dll /s
regsvr32 Gpkcsp.dll /s
regsvr32 Slbcsp.dll /s
regsvr32 Sccbase.dll /s
regsvr32 Softpub.dll /s
regsvr32 Wintrust.dll /s
regsvr32 Initpki.dll /s
regsvr32 Rsaenh.dll /s
regsvr32 Mssip32.dll /s
regsvr32 Cryptdlg.dll /s
regsvr32 Msxml3.dll /s
What these statements do is re-register the cryptographic files for
Windows XP. Usually blown encryption is an effect caused by a virus
