Top 10 Free Portable Anti-Malware Software to Have on Your Pen Drive

One thing that almost every Windows user should do is protect and keep their computers infection free. That being said, there will be times where no matter how careful you are, your system might get infected with a malware or virus. There may be several reasons for this like sticking your friend’s infected thumb drive into your computer, clicking on shady ads, visiting infected websites, etc.

More often than not, in these situations, the anti-malware software installed on your system may not work as it should. To deal with that, here are some of the best and free portable anti-malware software.

1. Microsoft Safety Scanner (1 MB)

Microsoft provides many in-house tools that help protect your PC. One of them is the Microsoft Safety Scanner that does on-demand scanning and removes any virus or malware findings. One thing to note about Microsoft Safety Scanner is that the application expires after 10 days of downloading. This is because of the out-dated anti-virus and malware definitions.

Pros: Microsoft Safety Scanner is an in-house solution that is fast and reliable.

Cons: Since there is no auto-update option, you need to download the application every 10 days.
