This is general advice only on aswMBR and not specifically for you:
That is why it shouldn't be used unless recommended and then only under advice from someone experienced in its use and the information it produces.
To start with you must be able to diagnose early scans, and find there is a reason to run a program like those mentioned -
It could seriously impact on your system should you chose options where you don't know what the impact might be.
The unknown MBR could mean more than one thing and not always malicious. It could be an indication that malware has modified the MBR code, but you would likely be experiencing other symptoms.
Perhaps more commonly this could be because of the system that you have, Dell, Acer, etc. where they have got a manufacturers recovery console and recovery partition.
To achieve that they have to customise the MBR record, if anyone chose Fix in this instance they would be wiping that custom MBR code and would lose access to that recovery console.
So care has to be exercised when using tools such as these as that may return information which could be incorrectly acted on.

Basically, you need to be able to pre-diagnose the problems and the reasons for selection of a relevant tool -
Reasonably objective in saying that you must know how to read scan results, and only apply the required tool to solve your problem.
As always, incorrect diagnostics can cause major problems in removal of incorrect programs and render a system useless -
