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. it’s best to check for malware if your PC is acting up and we’ll show you how to do it yourself
Step 1: Enter 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.
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.
You may find that your PC runs noticeably faster in Safe Mode. This could be a sign that your system has a malware infection, or it could mean that you have a lot of legitimate programs that normally start up alongside Windows. If your PC is outfitted with a solid state drive it’s probably fast either way.
Step 2: Delete temporary files
Now that you’re in Safe Mode, you’ll want to run a virus scan. But before you do that, delete your temporary files. Doing this may speed up the virus scanning, free up disk space, and even get rid of some malware. To use the Disk Cleanup utility included with Windows 10 just type Disk Cleanup in the search bar or after pressing the Start button and select the tool that appears named Disk Cleanup.
There are two types of antivirus programs. You’re probably more familiar with real-time antivirus programs, which run in the background and constantly watch for malware. Another option is an on-demand scanner, which searches for malware infections when you open the program manually and run a scan. You should have only one real-time antivirus program installed at a time, but you can have many on-demand scanners installed to run scans with multiple programs, thereby ensuring that if one program misses something a different one might find it.
If you think your PC is infected, we recommend using an on-demand scanner first and then following up with a full scan by your real-time antivirus program. Among the free (and high-quality) on-demand scanners available are BitDefender Free Edition,Kaspersky Virus Removal Tool, Malwarebytes, Microsoft’s Malicious Software Removal Tool, Avast, and SuperAntiSpyware.
If your problems persist after you’ve run the threat scan and it has found and removed unwanted files, consider running a full scan with Malwarebytes and the other scanners mentioned earlier. If the malware appears to be gone, run a full scan with your real-time antivirus program to confirm that result.
Before launching your web browser, check your homepage and connection settings. For Internet Explorer right-click the Windows 10 Start button and select Control Panel, thenInternet Options. Find the Home Page settings in the Generaltab, and verify that it’s not some site you know nothing about. For Chrome, Firefox, or Edge, simply go to the setttings window of your browser to check your homepage setting.
Once you have backed up everything, reinstall Windows either from the disc that came with your PC, by downloading the installation image from Microsoft, or by using your PC’s factory restore option, if it has one. For a factory restore you typically must press a certain key on the keyboard during the boot process in order for restore procedure to initialize, and your PC should tell you what key to press in the first few seconds after you turn it on. It there’s no on-screen instructions consult your manual, the manufacturer, or Google.
