Hi, Leo. I’ve been an avid follower of your Ask Leo! and love it. I’ve had a
problem recently with my PC and internet-connected TV. I’m running a Dell
Inspiron Home Edition with Windows 7. My TV is a Sony. Both are connected to
the internet through PC. We came home and the PC was flashing mallware and
mallbites was attacked and will no longer work. Please download a fresh copy.
After trying the PC to see what was affected, the printer would not work. The
CD/DVD would no longer work. I installed a fresh copy of mallware and mallbites
and ran it, but did not find anything. I ran System Restore to an earlier date
and now all seems fine. My TV wiped out all stored programs. Onscreen guide is
gone. Most internet settings were gone. My question: Is it possible for a TV to
catch a bug from my PC? Am I losing my mind?
In this excerpt from
Answercast #52, I look at a computer connected to a TV that suddenly lost
settings. Sounds like a power problem!

Sudden TV malfunction
No, you’re not losing your mind.
I will want one piece of clarification. I don’t know what you’re referring to
when you say “mallware” and “mallbites.” There is a program called Malwarebytes
but it’s a program called “Malwarebytes.” There are not two separate things. I’m
going to assume that’s what you were referring to.
You know what this really feels like? As I read this question, what came to
mind immediately was a power hit.
By that I mean, while you were gone, something happened to the power to
these devices. Perhaps it just went out and came back on again. Perhaps it was
much less clean than that. Perhaps it went down a bit and then up again and
then down a bit.
All of this can happen very quickly with respect to power. And, when power
gets noisy like that (when power goes down and comes back and goes down and
comes back) computers and other digital devices can react very negatively.
The fact that your TV lost all of its settings are really what made me think
about this. It clearly caused some things to go wrong.
Like I said, I’m assuming it’s a power hit. It feels like a power hit and
it’s just one of those things where the symptoms so closely match the kinds of
things that I would expect after a power hit that I’m going to assume that.
Honestly, that’s probably what happened.
To actually answer your question, “Can a TV get a virus from your PC?”
No. TV’s are typically running other operating systems to the extent that
they’re running an operating system at all. Very few of them that I know of
will actually run Windows. If they do, maybe it’s an embedded Windows, which
again, is enough difference from Windows on your desktop that things like
malware would not apply.
So, like I said, I don’t think it’s a malware issue at all. I really think
it’s something much more mundane. Something related to your power.
Brownout and surge protection
If this happens often, if this happens frequently, it might be time to look
into something like an uninterruptible power supply or UPS. Or it could be as
simple as turning the devices off when you’re not using them.
As someone who leaves my machine on 24 hours a day, I know that turning off
all the time would be a hassle. So I definitely understand that may not be the
first thing you reach for.
But, like I said, if this is something that happens frequently, if you’re in
an area prone to power problems, then it’s probably something you ought to look
