".rhuphem" extension. Am i infected?

[Senthil Kumar Palani]

My files in Windows OS automatically got turned into ".rhuphem" extension. For example, if my file name is "sk.pdf", it is automatically turned into "sk.pdf.rhuphem". I can't open the files now. Does anybody know the solution. Thanks in advance.

just pdf or any extension like .exe ,etc.
If it any, yes, it sound like a malware.
