A tech from MacKeeper wishes access to my computer for licensing and activation. Is this a scam? I paid for a version of MacKeeper which may be a mistake. Their tech  wants me to allow them to access my computer as in have access to my desktop files, etc. They say it is to fully license and engage the program . I have not done it as of yet.  

Is this typical when activating? I'm not comfortable letting them have control of my computer
Do not do this.
There are exactly zero reasons a tech, or anyone else for that matter, would need remote access to your computer to &quot;fully license and engage a program.&quot;
That phrasing alone is more than enough to elicit a high degree of skepticism of the intention and/or competence of the &quot;tech&quot; who is looking to access your computer.
For just a brief (hypothetical) moment; giving the &quot;tech&quot; the benefit of the doubt and assuming his motives are genuine, how good can this software be that it needs special handling to activate?
Bottom line...
You don't need this software, avoid it.
