If your antivirus software tells you that it found a potential threat called VBS:Malware-Gen during a routine scan, don’t panic, but do take this warning seriously. It means your Mac could be a risk of malicious software exploitation.


These threats pests often sneak in through spam emails, infected websites, or by clicking suspicious links. Once installed, VBS:Malware-Gen can quickly spread across your system, giving hackers access to your data and potentially taking control of your Mac. It’s important to act fast to stop the malware from doing more harm to your device. To ensure that doesn’t happen, we’ve broken down ways to help you check your Mac for malware.


Before we begin


We understand that not everyone is a security expert, and no one necessarily knows how to check their Mac for malware, which is why we spent years developing MacKeeper, an antivirus software specifically to keep your Mac safe.


While Apple devices come with basic antivirus features, reliable antivirus software like MacKeeper handles all security needs, defending your Mac against malware and malicious attacks.


Here’s how to protect your Mac from unwanted treats:

  1. Download and launch MacKeeper.
  2. Select the Antivirus scanner.
  3. Start your scan by clicking Launch Antivirus.
  4. Wait for the scan to complete and remove any threats found.

If you think your Mac may be infected, or to prevent a potential cyberattack, it’s best to use a trusted antivirus software like MacKeeper.

What is VBS:Malware-Gen

VBS:Malware-Gen is a malware created using Visual Basic Scripting language (VBS). Antivirus programs use this term when flagging VBScript files with characteristics similar to malware. VBS:Malware-Gen collects personal data and installs additional malware onto your computer.

Quick overview on VBS:Malware-Gen

A few years ago, Avast antivirus users received a warning from the software that they had found a threat called VBS:Malware-Gen and advised them to do a full system scan.


Avast users initially claimed  VBS:Malware-Gen was a type of Trojan that accesses devices via corrupt downloads or websites. However, Avast debunked this claim, stating that it isn’t a Trojan or any other kind of virus, but rather a result of a “false positive.”


They apologized for the scare and assured users they would be adding more checks during the software’s creation and testing to avoid similar errors in the future.

What does VBS:Malware-Gen do

Once any Trojan virus infects your Mac, it can wreak havoc on your entire system and jeopardize your data. These are some things that could happen if your MacBook is infected by VBC:Malware-Gen:

  • Data theft. As malware is specifically designed to steal sensitive information, like bank details and other personal data, it can result in financial loss, compromized privacy, and potential identity theft.
  • System disruption. A Trojan virus can cause it to disrupt your software's normal operation, potentially making your device crash or become unresponsive.
  • Remote access. The malware gives hackers unauthorized access to your MacBook, allowing them to carry out malicious activities remotely.
  • Ransomware. You might come across malicious software that is created to block your access to your computer unless a ransom is paid.

Are you now scared of these undesired consequences for your Apple device? Continue reading to learn how to avoid this problem and to stop VBS:Malware on Mac.

What to do if you get a VBS:Malware-Gen warning

If you’re using Avast and still come across a VBS:Malware-Gen warning on your Mac, the best to do is to avoid interacting with it. Though Avast claimed the virus doesn’t exist, you should still take the warning seriously. Make sure your Mac is updated with the latest Avast antivirus software to run a full scan to fix any issues.


If updating Avast doesn’t fix the alert, you might want to uninstall it and consider using MacKeeper as another antivirus software. Why? It comes with a malware removal tool that checks your device for all types of malware, like adware, spyware, and worms. If it does find VBS:Malware-Gen, you can easily remove it with a click of a button.

Is your Mac infected with malware

Despite MacBooks coming with built-in protective features, your device can still get infected by malware. While Apple has designed their devices to come with security measures, it’s still possible for hackers to find ways to infect your macOS with malicious software.


One of the most common signs is that your Mac has suddenly become much slower than usual. While this slowdown could also mean you need a software update, if you’ve noticed these other signs of malware, it’s likely your Mac is infected:

  • Apps on your Mac have started becoming unresponsive.
  • Unfamiliar icons have started appearing on your desktop.
  • Your Mac starts crashing or freezing unexpectedly.
  • Annoying pop-up ads keep appearing.
  • Your internet connection slows down for no apparent reason.
  • Your browser's homepage or default search engine changes without your permission.
  • You notice strange browser extensions or add-ons that you didn't install.
  • You're constantly redirected to random websites while browsing.
  • Your antivirus software or firewall gets disabled without your knowledge.
  • You get pop-up messages asking for sensitive information like passwords.
