everytime I start my computer I get a Windows Installer box that says preapring to install (install what???) and then it changes to MS Office Basuc and says configuring MS basic office. A status bar appears and then an error message 1933. I do not know what these boxes are for and why they keep coming up.  This problem started at the same time as slow internet problems and changed search pages. I learned about spyware and installed adware and spybot which founf over 100 problems and cleaned them up. But I am still having problems with with home page on IE and search page on AOL.  As well as this annoying windows installer box. Speed has improved, back to normal (using cable modem)

ANy help greatly appreciated, I am not that knowledgeable.
