Adobe Reader does not install DLL files in the application data of users. May be that this files comes from an virus.
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:
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.
Virus scans doesn't found all things.
Run msconfig and remove this entry from the startup tab.
That sounds normal if you just deleted the file rather than whatever caused it to load. Sounds as if your virus scanner isn't doing its job. Still, that error message is much better than having the virus.
