How to avoid malware in the future
  • Beware of sites that may cause you to download unwanted software. For example, if you win a contest or get copyrighted content at no charge.
  • Beware of encrypted archives, like .zip files with a password required, that may bypass antivirus detection scans.
  • Beware of warnings about viruses or infected devices, especially if you haven’t recently used a virus scanner.
  • Avoid insecure connections when you visit sites and don’t download files from sites that don’t start with HTTPS. Learn how to check if a site's connection is secure.
  • Pay attention to Safe Browsing download warnings. To avoid antivirus detections, malicious actors may ask you to turn off or ignore warnings.
  • If a popup about a program update or download seems suspicious, don't click on it. Instead, go to the program's official website to download it.
