Just disable unlimited health function, kill the rats and enable again thats a perfect work-around for me. Rats don't spawn that many so it's not really gameplay breaking.
Your antivirus or security product is falsely identifying our trainer or DRM as a virus or Trojan. All of our files are 100% safe and it is typical for some security products to block trainer injections. Please see our antivirus warning page for more information. You can either whitelist the trainer in your security product settings, temporarily disable the software or uninstall it and find a product that does not routinely flag our trainers as false positives. Please note that no two trainers are alike. We use different injection methods and security templates all the time. Some or none may be detected and then suddenly one might be. Rest assured these files are safe.
Extract trainer and make sure trainer/launcher/editor is in a folder excluded from virus scans. Empty quarantine folder if needed or set anything trainer related (paths and EXE's) to ALLOW. Disable any Live/Active/Real-Time tools which may trigger false positives in security software which may terminate the game/trainer when it's activated or options used.
may need to be added to exclusions as well. Run trainer as admin, read the instructions and try again.
