My system is using vivid workshop and it has file with .dll extension. I am using Avast antivirus software. Whenever it scans system it detects this .dll file as a Trojan file. i always give command to skip the file while scanning. Though my system is not giving any unhealthy symptomsí, I have installed the vivid in the system. So what can be the issue, can anyone suggest me the solution. I have used the software for years but every time I face this issue with my antivirus. Please suggest me the solution.
