how do I check whether avg is still active on my computer?

I have recently bought a new computer.  On my previous computer, I installed Microsoft windows10 and signed up for a normal office package.  However, it was difficult to keep windows 10 up to date (the Microsoft updates nearly always failed and I had to resort to a sequence of switch of, switch on moves to restore the system to working mode.  Since I got the new computer, I am unsure whether it continues to use my AVG virus checker etc.  Clearly, Norton came with the new computer and it appears to have done some virus checking while trying to persuade me to sign up. I have not done so but I get messages from Norton saying that it has blocked 'suspicious activity'.  Although my laptop was protected by a company AVG scheme, I suspect it is no longer, and I have not moved the laptop onto this same licence - although it seems I ought to be able to.  I'm happy to renew my AVG licence but I need to check it is doing some good in my present situation.
