Learn common signs of malware, how to respond safely, and steps to protect your device and accounts using antivirus tools and security best practices.
Following all the general electronic security guidelines, especially running a virus scanner to protect your computer and your information, can be the best defense against malware.
Between scans, keep an eye on your computer for changes in behavior, like:
- Sluggish processing speed for no apparent reason
- Not responding to your commands to shutdown or restart
- Intrusive ads appearing in places where you didn’t see them before
- Sending you to websites you weren’t trying to visit
- Sending emails without your consent
- Your browser homepage changes without your consent
- Device battery suddenly, and repeatedly, drains unusually fast
- Unexpected new icons or toolbars appear on your desktop or in your browser
Expert tips:
- If you have any suspicion your device might be infected with malware, immediately stop all online activities that involve usernames, passwords, or other sensitive information. This includes banking and shopping activities, accessing private work files, etc. Doing so may help prevent further harm.
- Run a trusted antivirus program immediately. If you don’t currently have one, two options are Avast Free Antivirus or Malwarebytes.
