Millions of viruses are made every hour. One of it's effect when it enters your Desktop or Laptop, is the corruption of your OS, I experienced the corruption on my computer, and it's pure chaos!!!! If you continue asking this obvious question, I'll let you experience the corruption and Trojan viruses I can offer you. Just tell me.
Scan once every month at least, your first scan should be a thorough one and then after that you can run quick scans (unless you change your system in a major way or find it running poorly)
