Adobe Reader has dll files, but not under that path.
Anyway, the virus scan didn't show anything, after removing the files from that location I receive the following error:
RegSvr32
The modile C:\Users....\AppData\Local\Adobe\bbqapgn.dll failed to load. Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files.
The specified module could not be found.
