Ok JanetsQueSera. I think I know now what is going on. You are mistakenly clicking the add with the green "Download". unfortunately these are tacticts done in web sites. What you should have done was to read the article and you would have seen an URL address in blue that said:
http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exeYou can click the address above and download the MPCR.exe program to your desktop or a place where you can find later on to execute.
after you apply MPCR.exe, you can follow Bob3160's guide for a successful Avast! instalation, or follow mine:
1.)
Very important to remove all remains of other AVs installed before Avast. Use this site to execute uninstall utilities for other AVs.

aswclear.exe 3.) Download and save a fresh copy of Avast! to your desktop.
http://files.avast.com/iavs5x/avast_free_antivirus_setup.exe4.) Open Avast! > Settings > Troubleshooting > Uncheck " Enable Avast! self-defense module ".
5.) Uninstall Avast! normally through Control Panel > Programs & feature ( Vista, W7 ) or Add and remove programs ( XP ). Reboot. If you can not complete this step, continue with step # 6
6.) Even if you were able to uninstall Avast! in step # 5, it is important to run aswclear.exe in safe mode for any Avast! you may have had before, e.g. v.6 o v.7, and then for v. 8. Reboot into normal mode after uninstall.
How to use aswclear:

7.) Reinstall fresh copy of Avast! and reboot.
Be aware. Avast! will offer Chrome during installment. Remember to opt-out if you do not want it.
