How to remove malware from your Windows PC

CERT-LatestNews ThreatsStrategic

Beware the signs of a potentially malware-infested PC: slower-than-usual performance, the recent occurrence of lots of pop-ups, and other weird issues. It’s possible your system has been infected by a virus, spyware, or other nefarious entity—even if you have an antivirus program installed. Yes, out-of-the-ordinary behavior is sometimes the result of hardware issues, but it’s best to first rule out malware if your PC is acting up. Here’s a step-by-step guide for taking action.

Step 1: Enter Safe Mode

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.

If you think your PC may have a malware infection, boot your PC into Microsoft’s Safe Mode. In this mode, only the minimum required programs and services are loaded. If any malware is set to load automatically when Windows starts, entering in this mode may prevent it from doing so. This is important because it allows the files to be removed easier since they’re not actually running or active. 

Sadly, Microsoft has turned the process of booting into safe mode from a relatively easy process in Windows 7 and Windows 8 to one that is decidedly more complicated in Windows 10. To boot into Windows Safe Mode, first click the Start Button in Windows 10 and select the Power button as if you were going to reboot, but don’t click anything. Next hold down the Shift key and click Reboot. When the full-screen menu appears, select Troubleshooting, then Advanced Options, then Startup Settings. On the next window click the Restart button and wait for the next screen to appear (just stick with us here, we know this is long). Next you will see a menu with numbered startup options; select number 4, which is Safe Mode. Note that if you want to connect to any online scanners you’ll need to select option 5, which is Safe Mode with Networking.
