Is your computer running slower than usual? Are you getting lots of pop-ups? Have you seen other weird problems crop up? If so, your PC might be infected with a virus, spyware, or other malware—even if you have an antivirus program installed. Though other problems such as hardware issues can produce similarly annoying symptoms, it’s best to check for malware if your PC is acting up and we’ll show you how to do it yourself.

Before you do anything, you need to disconnect your PC from the internet, and don’t use it until you’re ready to clean your PC. This can help prevent the malware from spreading and/or leaking your private data.
