Antivirus software protects your computer from viruses and other harmful programs. It works by:
- Scanning for threats
- Removing any viruses it finds
- Preventing new infections
PCI DSS requirements
To process card payments safely, you must:
- Install antivirus on all computers that handle payment data
- Keep the antivirus updated regularly
- Use software that can detect, remove, and protect against all types of malware
Why this matters
Without antivirus protection:
- Hackers could steal customer card data
- Your systems could be damaged or shut down
- You cannot become PCI DSS compliant
Important: Where a requirement of your PCI DSS, you must confirm that you have antivirus software installed before you can be certified as PCI DSS compliant - this isn't optional.
The bottom line
Think of antivirus as essential protection, like locking your store at night. It's a basic security measure that every business needs to protect customer data.
