I should add... the "1 or 2 percent" corrupt pdf files includes some that are NOT actually corrupt. However, Adobe Reader cannot open those files, but will give error messages indicating they are corrupt. Likewise, CorruptedPDFinder may also indicate the same files are corrupt.

Re-download a pdf file like that repeatedly, and Adobe Reader will always fail to open it.

However, open the same pdf file in PDF-XChange Editor, and then save a copy. Then, Adobe Reader will open the "copy" (which may be about 5% smaller in size than the original), without error...

Another pdf viewer that's free, small, fast, and more tolerant of alleged "errors" -- and that also can display many types of eBooks -- is the Sumatra PDF Viewer:

"Sumatra PDF is a PDF, ePub, MOBI, CHM, XPS, DjVu, CBZ, CBR reader for Windows"
