Avast Uninstall Problems

How would i do that with FRST?

Just do the in-place-repair as explained on the sevenforums.

Could i not possibly copy those two files from one of the working computers and then just them onto a broken computer using the copy command on cmd prompt?

No, because this one is created by the system and is specific to it

C:\Windows\system32\codeintegrity\Bootcat.cache IS MISSING <==== ATTENTION

I created a system image off of one of the working computers and then i created a recovery disk, i then loaded the system image onto a hard drive, i then booted the computer into the recovery disk and then used system recovery to load the system image onto the computer. Hope if anyone has this problem they can use this information and use the help from eddy and essexboy, thanks so much for the assistance.
