Frequently asked questions

Is Malwarebytes free antivirus?
The free download is an on-demand scanner and remover, not an always-on antivirus. Real-time protection is part of Malwarebytes Premium.
Can I run Malwarebytes free alongside another antivirus?
Yes. Because the free version is not resident, it does not conflict with Microsoft Defender or a third-party suite.
How do I run a free Malwarebytes scan?
Install the free version, click Update, then Scan. A full scan on a typical PC takes a few minutes to half an hour.
Does Malwarebytes remove trojans?
Yes, it removes trojans, adware, spyware, browser hijackers and many potentially unwanted programs. For a deeply compromised system, also run an offline scan from Windows Security.
