Can you be more specific? Exactly what goes wrong?
The official site for downloading ComboFix
is provided in the authorized Guide and tutorial on How to use ComboFix
. The link in that guide redirects to ComboFix Download page
hosted by BleepingComputer.
There are a number of unofficial sites
which host various unauthorized versions
of ComboFix (many of which are outdated) or imitations which claim to be ComboFix but redirect to downloading questionable software instead. For example, ComboFix.org and ComboFixdownload.com offer unauthorized versions
but are not affiliated with the legitimate tool created by sUBs.
