can't install any antivirus software - Help

Can't install any antivirus software - all installations fail

Hi, I have windows XP SP2 installed on an IBM T41 laptop
I had AVG antivirus until one day it stopped working (didn't even load on windows startup), so i tried to uninstall it, and then re-install it but it didn't let me reinstall it.
I'm unable to reinstall any other antivirus i tried to (such as NOD32, spyware-doctor).
I believe there is a virus on my PC that prevents me from installing any antivirus software.
Another issue I have is that my wireless doesn't work anymore. I get a message saying: "windows can't configure this wireless connection. If you have enabled another program to manage this wireless connection, please use that software" - i didn't install any other software to manage my wireless.

I cannot use system restoration as well (both under normal and safe mode).

Please help......

If it won't run, rename the downloaded mbam-setup.exe file to mb.exe to help work around certain malware that will block it from being run.
If it still will not run.
1: Go to Control Panel > Programs and Features and uninstall Malwarebytes.
Next redownload Malwarebytes but rename it before you download it to your desktop. As you are in the process of downloading when you get to the point that the "enter name of file to save to" box appears, in the "filename" slot, rename mbam-setup.exe to something.exe, then click Save.
If it installed but will not run, navigate to this folder:
2: C:\Programs Files\Malwarebytes' AntiMalware
At the top of the page, Tools > Folder Options > View, click > Show hidden files and folders and untick > Hide extensions for known file types.
Rename all the .exe files in the Malwarebytes' Anti-Malware folder and try to run it again.
When it opens, update 1st.
If it won't update after installing, update manually.
Download & install.

Malwarebytes is one of the tools recommended by most sites dealing with HiJackThis logs as a program to run before presenting the log for expert infection help.
Here are few of them.
