McAfee Stinger has been removed from the Portable App Directory due to malware-like behavior. Running the current releases of McAfee Stinger on any Windows PC will automatically install the 'McAfee Validation Trust Protection Service' (mfevtps.exe) to the local machine without a prominent notice to the user. There is a reference to it only buried in the EULA. Once installed, these files are exceedingly difficult to remove. No entry is made in Add/Remove Programs or Uninstall a Program, a service is installed and set to automatically start with Windows, the service can not be Stopped by the end user. This behavior is unacceptable from any application, portable or not. It should be noted that the service left behind does not appear to do anything nefarious to the local machine. It could simply be an error by the publisher, but it has not been addressed since it began occurring a couple weeks ago.
