Based on your initial troubleshooting, it appears your security software is incorrectly detecting VAT-Spy as malware. Probably due to the reputation database for your antivirus.
Your next troubleshooting steps would be to add the VAT-Spy program, exe, folder, or process to the antivirus exception list. This would exclude VAT-Spy from being scanned. If you’re not familiar with these steps, your security software documentation should explain how to accomplish this task.
False positives are common with most security programs because the vendor must balance your computer’s protection with user productivity and disruption. A tough balance indeed these days. I have experience with a variety of these programs, and each one I’ve had to maintain an exception list to allow application functionality.
