Smart Scan

Access this feature from: Protection ▸ Antivirus ▸ Run Smart Scan

When you initiate a Smart Scan, Avast scans your PC for the following issue types, then advises you of the findings:

• Viruses: files containing malicious code which may impact the security and performance of your PC.
• Vulnerable software: out-of-date software which hackers can use to access your system.
• Bad browser add-ons: browser extensions that are usually installed without your knowledge and affect the performance of your system.
• Weak passwords: passwords that are easy to decipher, used to access more than one of your online accounts, or compromised.
• Network threats: vulnerabilities in your network that may lead to attacks on your router and network devices.
• Colliding antiviruses: antivirus programs that are installed on your PC in addition to Avast. Multiple antivirus programs slow down your PC and result in ineffective antivirus protection.

Note: You can disable unwanted detections in your Smart Scan settings.
