Missing Mouse Cursors

Recently when dealing with rampant adware/spyware I discovered that my XP installed mouse cursors were all missing. I did try to run Go Back but I was unable to get them back. I think they were probably missing several days before I realized that all was not what it should be....
The only cursors remaining in the file are those that came with WindowsPlus. All high visibility, etc., which I prefer to use, have disappeared.
I used my WinXP install disk to reinstall Accessories/Cursors but they still aren't there.
I then renamed my original cursor file and created a new one in the hope to have it install in the new file. Nothing...
At one point I was getting a message that the file was corrupt, but I'm no longer even getting that message.
Any help would be appreciated... Thanks.
