Can't install any antivirus

Fuente
it doesn't allow me to install any anti virus/ security software i have tried nearly all i can think of,
first thing i tried ..
i did extensive research on the problem and decided it may be a maleware infection so i attempted to install malwarebytes programm it installed succescfully but refused to run
with the following message
"run-time error 339
component "vbalsgrid6.ocx" or one of its dependencies not correctly registered: a file is missing or invalid"
after doing abit of research i tried the following fix where i renamed the download and went into the program files showed all the hidden files and attempted to rename all the .exe files but it wouldn't let me re name any of them it just seems to stay the same so i gave up on that area.
i noticed that my disk backup feature kept continuously reporting failed due to there being insufficient memory on my hard drive also on my connection status icon it seems to say the same thing when i mouse over it " not enough storage is available to complete this operation. this is untrue ofc as i have over 60g free space remaining
i followed up on this issue and attempted to fix it. following this error code
0x800700E

Step 2.Replace the corrupted Windows Installer files:
==================
A. Enter Safe Mode:
1. Restart the computer.
2. Keep pressing the F8 key until the Windows Startup menu appears.
3. Choose Safe Mode, and press Enter.
Note: In Safe Mode, your system display and Desktop will look and perform differently than in Normal Mode. This is only temporary.
B. Replace the dll files:
1. Click Start-> Search.
2. Select "All files and folders", and then search for the following files:
MSI.DLL
MSISIP.DLL
MSIHND.DLL
MSIMSG.DLL
MSIEXEC.EXE
If we find any of the above files, please right click to rename this file to (such as MSI.old). Please understand that we may not find all the files listed above. If so, it is normal. Please continue to search for the rest of the files.
3. Put the Windows XP CD to CD-ROM.
4. Click Start->Run.
5. Type cmd and press enter.
6. In the DOS Window, type the following command and press Enter after every line.
expand -r D:\I386\msi.dl_ c:\windows\system32
expand -r D:\I386\msihnd.dl_ c:\windows\system32
expand -r D:\I386\msisip.dl_ c:\windows\system32
expand -r D:\I386\msimsg.dl_ c:\windows\system32
expand -r D:\I386\msiexec.ex_ c:\windows\system32
Note: I am assuming that your CDROM drive letter is "D". Please use the actual drive letter to substitute "D". There is a space before C:\WINDOWS.
7. Click start and choose run. Type “MSIEXEC /regserver” (without quotation mark) in the open box and click OK
