How to remove a computer virus / malware

Is your work computer is running slower than usual? Are you getting lots of pop-ups? Have you seen the 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. Through other problems such as hardware issues can produce similarly annoying symptoms, it's best to check for malware if your PC is acting up in the business and we'll show you how to do it yourself.

Step 1: Enter Safe Mode

Before you do anything, disconnect your PC from the internet when you need to, and don't use it until you're ready to clean your PC. This can help prevent the malware from spreading and/or leaving 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 to work, entering this mode may prevent it from doing so. This is important because it allows the files to be removed since they're easier note actually running or is active.




Sadly, Microsoft has turned the process of booting into Safe Mode from a relatively easy process that is decidedly more complicated in Windows 7 and Windows 8 to Windows 10. To boot into Windows safe mode, first click the Start button, the power button and select Windows 10, 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. The next screen click the restart button and wait for the next window to appear (just stick with us here, we know this is long). Next you will see a startup menu with numbered 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 is noticeably faster in Safe Mode Russian. 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 in the business 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 to get rid of some malware. To use the Disk Cleanup utility included with Windows 10 just after pressing the Start button and type Disk Cleanup in the search bar..




Step 3: Download malware scanners

Now you're ready to have a malware scanner do its work—and fortunately, running a scanner is enough to remove most standard infections. If you already had an antivirus program active on your computer, you should use a different scanner to check for malware, since your current antivirus software may have detected the malware note. Remember, no antivirus program can detect 100 percent of the millions of malware types and variants.

There are two types of antivirus program. You're probably more familiar with real-time antivirus program and run in the background which 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, one program misses something by ensuring that there are a different one night to find it.

If you think your PC is infected with your business, we recommend using the on-demand scanner first and 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.

Step 4: run a scan with malwarebytes

For illustrative purposes, we'll describe how to use the Malwarebytes on-demand scanner. To get started, download it. If you disconnected from the internet for safety reasons when you first suspected that you were might be infected, reconnect to it so you can download, install, and update Malwarebytes; then disconnect from the internet again before you start the actual scanning. If you can't access the Internet or you cant download malwarebytes on the infected computer front, download it on another computer, save it to a flash drive and a USB flash drive to the infected computer.

After downloading Malwarebytes, run the setup file and follow the wizard to install the program. First, the program opens, keep the default scan option (“Threat Scan”) is selected and click the start Scan button. It should be Check for updates before it runs the scan, so just before that happens, make sure you proceed.
It offers through a custom-scan option, Malwarebytes recommends that you perform a threat scan as the first scan of all the infections that often friends anyway. Depending on your computer, the Quick Scan can take anywhere from 5 to 20 minutes, whereas a custom scan that might take 30 to 60 minutes or more. Business Malwarebytes While scanning, you can see how many files or objects the software has already scanned, and how many of those files it has identified either as being malware or as being infected by malware.

If Malwarebytes automatically disappears after it begins scanning and won't reopen it from, you probably have a rootkit or other deep infection that automatically kills scanners to prevent them from removing it. Though you can try some tricks to get around malicious technique, you might be better off reinstalling Windows after backing up your files (as discussed later), in view of the time and effort, you may have to expand to beat the malware.

Malwarebytes will show you the results before the scan job is complete. If the software gives your system a clean Bill of health, but you still think that your system has acquired some malware with Malwarebytes and trying the other scanners mentioned earlier, consider running a custom scan. If Malwarebytes does find infections, it'll show you what when they are complete the Scan Job. Click the remove selected button in the lower left to get rid of the specified infections. Malwarebytes may also prompt to restart your PC for the complete removal process to get in order which you should do.

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.
