How to remove malware from your PC with Malwarebytes

Despite all your vigilance, it can happen that malware reaches your system, especially in the presence of a zero-day flaw (security flaw which is not yet known by the publisher of software or that is not yet fixed) on Windows or on your software.

To repair your Windows PC and remove all the malware installed there, I explain how to use the most powerful anti-malware software that exists today: AdwCleaner and Malwarebytes.



AdwCleaner or Malwarebytes ?

Since October 19, 2016, AdwCleaner has been owned by Malwarebytes and is now called Malwarebytes AdwCleaner.

Although both target adware, spyware, browser hijackers, Potentially unwanted program (PUP), unwanted browser toolbars, etc. each has its own detection and suppression technology.

Completely free, these are two complementary disinfection software :

  • AdwCleaner is a standalone product that requires no installation. It has the advantage of being very fast, it scans your Windows PC in seconds. It must be executed manually.
  • Malwarebytes Free requires installation and has more functionalities (rootkit search, analysis of archives, etc.) with in particular the possibility of scheduling periodic analyzes. It also offers real-time protection in its Premium version.

Why use Malwarebytes ?

Just because no antivirus software is 100% effective, that’s why it is good to do antivirus scanning with other software.

On the software side, here is what you need to do to protect yourself against all types of malware : choose antivirus software, install it on your computer and let it act in the background. And once or twice a month, scan with anti-malware software like AdwCleaner and Malwarebytes.

Anti-malware VS anti-virus

Malware refers to all programs developed to harm a computer system. They include viruses, worms, Trojans and the threats they cause (rootkits, spyware, adware, etc.).

Today, all anti-virus software is anti-malware software. They have all evolved and act as both anti-virus and anti-spyware, anti-rootkits, anti-trojans.

Disinfect your PC with AdwCleaner

AdwCleaner is the malware disinfection utility preferred by Windows users. It scans the computer very quickly for adware, spyware and other junk, in addition to being light and very easy to use. It is still the benchmark standalone malware disinfection utility today.

AdwCleaner scans for malware only in the folders most likely to get infected, it doesn’t scan your entire drive. AdwCleaner is therefore the ideal tool to remove:

  • Adware.
  • The potentially unwanted programs or PUPs (potentially unwanted software or LPI).
  • Toolbars (toolbars grafted to the web browser).
  • Browser hijackers (who hijack certain web browser options such as the start page or the search engine).

Here’s how to use AdwCleaner :

  5. After restarting the PC, when Windows starts up, AdwCleaner attempts to remove the threats it has detected. You can see the number of threats it has successfully removed and compare it to the number of threats detected.
  6. Click the View Log File button for more information on the threats that have been removed and those that AdWCleaner has failed to delete from your system.
    Unwanted software is divided into several categories : Services, Folders, Files, DLL, WMI, Shortcuts, Tasks, Registry, Chromium (and derivatives), Chromium URLs, Firefox (and derivatives), Firefox URLs.
  7. If threats are still present, re-run a scan and clean up.
