Custom Permissions for Browser with Online Armor

I noticed you can set program permissions for programs with Online Armor, such as:

- Start applications
- Set global hooks
- Physical memory access
- Remote code
- Remote data modification
- Suspend process/thread
- Create executable
- Use DNS API
- Enumerate files
- Direct disk access
- System shutdown

All of these are set to n/a except Create executable is set to Allow.

Would it improve security to change any of these for Google Chrome, or is it secure enough? Would it affect drive-by downloads from Chrome?
