Apparently it's a special app by Kaspersky, not just the antivirus but by all means hire a tech. If my late husband were around, he'd walk you though it but he's off fixing St. Peter's database, so we can't just call him up anymore. But he was a whiz. If he only left me his supersecret password for the network I'd be ok, too, but it was SUPERsecret....so I have to take the whole wifi down and reinstall a new security code. Grr. Guys, put your secret stuff in a safety deposit box for after your demise, like passwords, etc, if you can't bear to share them with your wife.
