How to Update Malwarebytes
Malwarebytes does not install itself in the system tray. The way you update it is find it in your program files or find an icon it may have made on the screen, then click on it.
When it is updated you will see this. Click OK.
Now to run it make sure that “Perform full scan” is selected. Then click Scan. There is no need to purchase or register the product if you are going to stay with the freeware version of Malwarebytes.
The scan can take several hours. Do NOT run this scan concurrently with any other scan. We suggest starting the scan before you go to bed, keep your computer on, and your scan will be complete in the morning.
