combofix will not install

try to install it in safe mode.

Also try to run it in safe mode with network and redownload. Some malware will corrupt the download.

If you are able to download try to rename it to setup.exe or explorer.exe or iexplorer.exe since these names are usually not filtered by the malware.

Also try killprocess in windows to turn off any apps you dont need to free up combofix to install:

Can you be more specific? What OS are you using? does it download and not run or not download at all?
You may need to run rkill first in order to stop what ever is infecting you machine.

I agree with renaming Combofix; that may work. I thought you weren't supposed to run Combofix in safe mode? Please correct me if I'm wrong.
Also, did you try scanning outside of Windows, from a bootable AV CD?

You only run combofix in safe mode if it absolutely won't run in normal mode. Then run it again in normal mode.
