IMPORTANT:
Select the "home" option.
It's a FREE download
IMPORTANT:
You DO NOT NEED TO BUY A SUBSCRIPTION to run MalwareBytes.
It will run FOREVER IN FREE MODE.
It runs this way for about 30 days or so.
Then, it will ask if you wish to register.
You DO NOT have to register -- just say no and opt to continue using it "for free".
The difference between the paid version and the free version is:
- the paid version runs all the time "in the background"
but...
- the free version only runs when you launch it (but still is functional).
You CAN pay to register it if you wish. The cost is very reasonable.
Do this, and it will offer malware scanning/protection "in real time", continuously.
The free version is "good enough for me"...
