When you consider that Avast (Alwil) is celebrating it's 25th Anniversary this year, it's not
that hard to have been a customer that long. 
I'm not sure if you're being facetious (as was I) or math-challenged.

2014-25 = 1989
That's a *
very* long way from "the
early 1900's" - which I take generally to mean pre-World War I.

The way I see it 1989 is the
late 1900s. (Not that this has anything to do with the quality of avast!'s service - or lack of same. So apologies to the OP for digressing from the principal concern.)
