AOL required me to upgrade McAfee that is causing Windows problem

AOL essential me to upgrade McAfee. For the duration of the installation course of action, just after the old McAfee was deleted, the laptop locked up not completing the install. Restarted AOL and
attempted once again but got no additional than the signin page for McAfee, the subsequent page was blank. Also, Process Restore is blank when opened. I also now have blank Most important Pages on Quickbook now. Could anything inside the installation course of action have corrupted Windows? So far it appears that all of the other applications are operating appropriately. Also can not update Windows XP. When I attempt it begins to load the updates then a box comes up saying the updates failed. Is this all a element of your similar trouble? Thanks for the time.
