I have been using Combofix for a long time. With the current release, when I execute the program I get a message box that says. "Current date is 2016-06-24. Combofix has expired. Click yes to run in REDUCED FUNCTIONALITY mode. Click no to exit. When I click yes, the program aborts and deletes the file.
Is it possible some virus is attacking the Combofix program? Any ideas on how to proceed?


I am not running in safe mode. I also forgot one important part of the message. "Combofix has expired" Hope that helps

Are you running it in Safe Mode?

There is another recent topic about the same thing which suggests that is why you could have reduced functionality mode.

First of all, Combofix should never be used except under the direct supervision of someone who has been trained in its use. Used properly, Combofix is like a surgeon's scalpel - a powerful tool in the right hands. Used improperly, Combofix is like a nuclear weapon - quite capable of wiping out your entire PC.

With that disclaimer out of the way...

Combofix has a short "shef life". You should always download the latest version of CF just before you are instructed to use it. Combofix will switch to reduced functionality mode when it expires (roughly a week after it is released, if I remember correctly).

System requirements for ComboFix are provided in the Authorized How to guide, on the authorized download page, and in the ComboFix usage, Questions, Help? - Look here topic.

At this time ComboFix can only run on the following Windows versions:
Windows XP (32-bit only)
Windows Vista (32-bit/64-bit)
Windows 7 (32-bit/64-bit)
Windows 8 (32-bit/64-bit)

Windows 10, Windows 8.1 and Windows 2000 are NOT supported by ComboFix.
If you attempt to use ComboFix on Windows 10, Windows 8.1, or Windows 2000 it should provide a message alert and exit. These are generic messages and intentional by design when attempting to run ComboFix on an unsupported Windows version.

As I noted in the other topic, the developer (sUBs) periodically releases updates and fixes for older supported operating systems. If you are encountering issues with supported operating system versions, you can start a new topic and ask sUBs at his home forum.
