File corrupted - MessageBox

[cridruki]

During start of hmonitor I'm getting a messagebox saying:
"File corrupted!. This program has been manipulated [...]"

Its a fresh installed hmonitor version 4.5.1.2.
The hmonitor.exe is 1760768 bytes.
I'm using Windows 7 Professional 64-Bit.

What can I do?

Hmonitor has internal integrity checking feature.
If it reports that the file is corrupted, something is wrong with your system.
First, thoroughly check your system for viruses and trojans.
Next, some poorly written antivirus programs behave as a viruses itself - they install several hooks into the system and alter the code of other applications.
So, you may check installed AV programs and temporarily disable them one by one.

I (temporarily) uninstalled ThreadFire. And now Hmonitor works
ThreadFire seems to install some kind of hooks to monitor application behavior. Unfortunately these hooks are incompatible with hmonitor's integrity check.

Thanks for your help.
