Hi,
If that was asked to me, I would hung up the call or close their chat.
I always consider Norton product with a backup scanner like Malwarebytes to be always good to protect my system from almost all threats.
Also you can use free maintenance tools like Ccleaner (www.piriform.com/ccleaner) to clean your junk files.
I suggest you NOT to touch any registry keys either for editing or deleting nor use the registry cleaner option.
I think I helped you clear your doubts.
In case of doubts, post back and we will be glad to help.
