RE: my security setup
What addon's you have for your browser?
You could add Malwarebytes Anti-Malware as an on demand scanner (free version).
Vipre AV is a good av so you are fine there. Do you have Viper's HIPS turned on?
Your security risk is Medium. Could I ask what you usually do with your system? Depending on the answer, we could provide you more suggestions.
A backup solution could also be handy, such as Macrium Reflect, Paragon Backup and Recovery.
You could also use Bufferzone Pro or Sandboxie as a virtualization software.
