How do I get an old (but still valid) subscription tied to my AVG account?

Hello,

My brother bought me an AVG Internet Security for PC licence (2 year licence), over a year ago, from a third-party vendor.  The licence key he emailed me obviously worked as I've been running AVG Internet Security on my PC ever since. 

However I didn't know how to register the licence to my AVG account, so this never happened.  I'm now running the free version of AVG Antivirus for Android on my phone and would like to upgrade this to the paid version using my AVG Internet Security for PC licence.  What steps do I need to take to register the licence bought by my brother, from the third-party vendor to my AVG account?

Thank you.

Thanks for this.  Replied to your email and your colleague resolved it for me.

Thank you.

You are most welcome!
You can purchase pro version of AVG Anti Virus for android from Google play store.
