How to Scan Your Computer for Viruses?
By default, Windows 10 uses the integrated Windows Security program, also known as Windows Defender, to search the computer for malware. Manual scans, on the other hand, are possible.
- To open Windows Security in Windows 10,
- go to the Start menu, type “Security,” and then press the “Windows Security” shortcut.
- You can also open Windows Security by going to Settings > Update & Security > Windows Security > Windows Security >
- Open Windows Security.
Tap “Virus & threat protection” to run an anti-malware scan.
In Windows Security, open the Virus and Threat Protection settings.
To check your device for malware, click “Quick Scan.” Windows Security will run a scan and report the results to you. If malware is detected, it will offer to automatically delete it from your computer.
In Windows Protection, manually scanning for viruses and other malware.
You can also run a search for a different security program if you want a second opinion—which is always a good idea if you’re worried you may have malware but your primary antivirus doesn’t notice anything.
Malwarebytes is a program that we like and recommend because it works well with Windows Security to provide an extra layer of protection for your computer. Malwarebytes’ free edition allows you to run manual scans on your computer to look for viruses and other malware. The paid version adds real-time security, but the free version will suffice if you only want to test a device for malware.
Malwarebytes are used to scan for malware on Windows.
Antivirus protection is not included with Windows 7. You can download Microsoft Security Essentials for free antivirus and run a scan with it. This offers similar support to Windows 10’s built-in security software, Windows Defender.
How to Check if a Process Is a Virus or Not?
You may be wondering if your machine is infected because you noticed an unusual process in the Windows Task Manager, which you can access by pressing Ctrl+Shift+Esc or right-clicking the Windows taskbar and selecting “Task Manager.”
The Windows Task Manager can be accessed from the taskbar in Windows 10.
It’s natural to see a large number of processes here; if you see a smaller list, click “More Information.” Many of these procedures have unusual and perplexing names. That’s perfectly natural. Background processes come standard with Windows, and your PC manufacturer might have added some, as well as applications you install.
The Task Manager in Windows 10 displays the processes that are currently running.
Malware that behaves badly can also use a lot of CPU, memory, or disc space, making it stand out. If you’re unsure if a program is malicious, right-click it in Task Manager and select “Search Online” to get more detail.
If you check the mechanism for details about malware, it’s a good bet you have malware. However, just because a procedure appears to be legal does not mean it is virus-free. It’s possible that a process claims to be “Google Chrome” or “chrome.exe,” but it’s really malware masquerading as Google Chrome and hiding in a separate folder on your machine. If you suspect you’ve been infected with malware, we suggest running an anti-malware scan.
On Windows 7, the option to search the internet isn’t open. If you’re using Windows 7, you’ll have to check for the process name using Google or another search engine.
What Are the Signs of a Virus?
Poor output, program crashes, and device freezes are all signs that a virus or some type of malware is wreaking havoc on your computer. However, this isn’t always the case: there are a variety of other issues that can cause your PC to slow down.
Similarly, just because your computer appears to be operating normally does not mean it is free of malware. Viruses a decade ago were frequently pranks that went amok and consumed a large number of machine resources. Modern malware is more likely to hide in the background, attempting to avoid detection in order to steal your credit card numbers and other personal details. To put it another way, modern malware is frequently developed by criminals for the sole purpose of making money, and well-crafted malware would not cause any visible PC problems.
Still, a sudden drop in PC performance may indicate the presence of malware. Strange applications on your device might be a sign of malware, but there’s no way of knowing for sure. Strange windows flickering onto your computer and quickly disappearing might be a natural part of the legitimate software on your device, as certain programs pop up a Command Prompt window when they upgrade.
Without actually searching the PC for malware, there is no one-size-fits-all piece of evidence to look for. Malware can cause problems on your computer, or it can be well-behaved while quietly accomplishing its target in the background. Examining your machine for malware is the only way to know for sure whether you have it.
