[ANSWERED] Can You Have Avast and Malwarebytes Simultaneously?

Users who rely on any sort of antivirus often have a common question in their mind whether they can have Avast and Malwarebytes at a time on their computer system. Now many people may think that what’s wrong to have them both? Aren’t both designed to defend against all malware? 

The simplest answer, in this case, is you shouldn’t have Avast and Malwarebytes

Simultaneously on your system. Yes, you can install them both and there won’t be any problem while doing so. But eventually, you’ll face some conflict between them.

Here, we’re about to explain the matter in a convenient way. So, take a few minutes and read the entire post.

Can You Have Avast and Malwarebytes Simultaneously

Is It Possible to Have Avast and Malwarebytes Together?

Before getting into the detail, let us clear a fact. Avast is a renowned antivirus program, while Malwarebytes is considered a top-rated antimalware program. That means Avast is intended to detect and eliminate all types of malicious programs from a system, while Malwarebytes is designed to safeguard the system from those malicious programs in advance. In short, one is better for prevention and the other one is better for cure. 

Now back to the point, when you try to use both software on your system, at a point they’ll cause potential issues including conflicting with each other. The simple reason is both of them make use of different technologies. So, whenever they scan the system, they identify each other as threats which are actually false positives. Even it has been found that Malwarebytes forces Avast to stop operating after a few minutes in this case. So, it’s clear that they’ll resist each other if you try to make them coexist.

Another problem they’ll create while being together is consuming a large amount of system resources such as RAM. The program resources will take space in the drive and while actively operating, both programs will require lots of RAM space to give their best. Overall, your system will get slow and respond less, the internet connection will be affected, and any of them can’t operate properly as they should. 

So, it can be said that you actually can’t have both Avast and Malwarebytes if you want a non-problematic security system. 

What Should You Have Between Avast and Malwarebytes?

As we’ve already mentioned that the work procedures of both programs are different from each other and they serve better according to their unique motive, if your system is already infected then you should use Avast to detect and remove the threats, otherwise use Malwarebytes to prevent your system from getting infected by potential threats. 

Frequently Asked Questions (FAQs)

Can I use Malwarebytes with another antivirus?

Yes, you can but not in a regular way. Malwarebytes typically create issues like conflicting with the other coexisting antivirus while operating. So, when you need to use any other antivirus along with Malwarebytes, you must ensure adding the antivirus’s resource files to Malwarebytes’ exclusions. 

Do I need an antivirus if I already have Malwarebytes?

Frankly speaking, no. If you already have Malwarebytes, you won’t likely require an additional antivirus. But make sure to have Malwarebytes Premium because it’ll surely provide the best protection against any malware and you won’t have to worry about it. 

Is it OK to run Malwarebytes and Windows Defender at the same time?

Yes, it’s okay. Windows Defender is Windows’ built-in security system and it’s designed in a way that it doesn’t conflict with other third-party security apps. Malwarebytes definitely offers better protection features compared to Defender. But if you want to ensure the strongest protection, you can use both (if there are no side effects). 


To conclude, it can be said that it’s better to avoid using both Malwarebytes and Avast at the same time. First of all, determine whether you need to prevent or cure your system from malware. Then install the relevant threat protection program accordingly. The fact is both programs perform better when they operate individually. Let us know if this post proves informative or helpful.
