SourceTree performance issues with antivirus

[Plinfut]

SourceTree is extremely slow on my Windows 10 machine. I even tried some legacy versions, but all have the same problem. It takes 2-15 minutes to complete any action. Performing a commit (3 actions: refreshing changed files, committing and pushing) often takes half an hour this way, making the program almost useless.

Disabling my antivirus (Trend Micro Maximum Security) solves this completely, but that is of course not a permanent solution. I already excluded C:\Program Files (x86)\Atlassian\SourceTree and my local copy of the repository from any scans and allowed sourcetree.exe and putty/pageant.exe through Windows Firewall, but sourcetree remains extremely slow. What else may I have to exclude from scanning or allow through the firewall to solve the performance issues without disabling my protection completely?

Configure your AV tool to exclude your source files and your project directories. This will stop it from interfering with ST accesses of those locations/files.

Apparently I had to restart my PC for the exceptions to take effect. The freezes are now down to 10-30 seconds, which is workable. Still not great, but I saw there are a lot of bug reports regarding slow performance, so hopefully it will decrease further in the next version.
