Hello Chrissie

 

Welcome to the Webroot Community,

 

No you do need need another Malware. Webroot is all you need. Webroot can indeed work along side other Anti Viruses. But i would think you wouldn't want to add more drag to your system.

 

WSA is an anti malware application, it cover/protects against numerous threats including spyware, etc. as per the Webroot website's description:

 

Get protected against the latest known and unknown threats: 

• Viruses and Spyware
  
  
• Anti-Ransomware
  
• Phishing Attacks

• Identity Theft
  
• Social Network Threats
  
• Unsafe Websites

 

Hope this is what you are asking?
