I did scans with Norton 360, Malwarebyte's anti-malware, Registry Mechanic. Norton found problems after I ran Malwarebyte. Registry Mechanic has a couple of entries that it cannot fix.
The computer (Vista Ultimate with SP) is much faster now. MY concern is that on July 12 a PROGRAM WAS LOADED ONTO MY COMPUTER AND i CANNOT GET RID OF IT.
The program is listed in Programs and Features / uninstal or Change a program.
It is listed simply as Amyuni PDF converter, no publisher and no file size. I cannot uninstal as windows syas that I do not have sufficient access to uninstall the program. I cannot find it in the Start menu, under all programs.
