NO operating system stated, sounds W7 like.?
there is no lifetime anything, SORRY!
my guess is some kind of marketing Hype,?
what do you expect for QVC, (avoid like the plunge, me)
that warning is , Microsoft, ant- malware engine protecting you.
(and anti-virus too)
it will see vast errors, cruising THE world wide web of infections.
Its ok, dont panic yet
run the clean,
let them both runs, 1 at a time, never both same time.
on Windows 10 its called Defender
click the tray icon and do a full scan
scans are NEVER risky .
scan it every day.
if kids use internet scan hourly (LOL)
think of the internet as a huge garbage can. (it's 10000x worse)
think of the scans like Shower and 3 doses of Penicillin

All versions if windows are a virus magnet
XP is worst
gets better every release.
W10 is the most safe! but has other issues, (spying that is easy to turn off ,ask)
and Linux vastly better, (search linux virus in the wild)
the most safe of all is booting running from CDROM or flash stick
running say windows 10 PE live CD
where nothing gets saved! ever.
or running a Virtual OS. ( i offered things to learn )
