According this thread:
Kompas Antivirus , I think Kompas could be used as a companion antivirus.
Work alongside existing with other antivirus software without any conflicts.
I have not tried it, but if it is properly designed to be a companion antivirus, I think it would be OK to use Panda and Kompas together

It is often mentioned in this forum that Advanced System Care may not be a good opinion when you need a system optimization tool.
Its optimization function is too aggressive, which could influence the stability of the system.
It is also mentioned by some users that the background service of it, called AdvancedSystemCareService, will use much CPU resource.
In my opinion, CCleaner should be a better opinion. I am using it and I find it safe to use.
Similar to CCleaner, Kerish Doctor is also spoken highly of by the users. So I think it should also be a good software in this field, though I have not used it ever.
