- How do we know if we have a virus?(13 votes)
- You can use a malware scanner to scan your device for any malicious files or software. There are a number of free and paid services that can do this.
Unfortunately though, there are also lots of fake versions of malware scanners and these are also commonly the targets of phishing attempts. So like the video mentions, make sure you install one from a trusted source!(4 votes)

- It is a file that can corrupt your device... generally it is used to steal your information or render it unusable. You can get it from unknowingly downloading it onto your computer by clicking shady advertisements or websites. (Which is kind of the whole point of this course).(5 votes)

Video transcript
- Mark, I'm pretty convinced that I need to protect my
devices from other folks. How should I think about that? How does one protect their device? - Yeah. The first piece is really
taking what the manufacturers and the companies behind
them are giving you. So, when you receive this notice that, you know, your phone is ready
to get a security update or ready to get a patch, it's really important to do that ASAP. The reason is that, once
that alert shows up, the attackers basically
know about a vulnerability. So it's kind of like if somebody says, you know, on allowed speaker, "Hey, your front door is unlocked." Like, the longer you wait, the more chance for someone to come in. So, I know it can be annoying, you're in the middle of a meeting, you're running for a taxi, what have you, but the sooner that you do that, the better you are protected. On Google devices, on Android phones, on our pixel phones, we push these out and try to make it so
it's as easy as possible. So there are very few steps, very few things for you to worry about. It will take a few minutes, it will use some wifi data, but that's probably the
first and best recommendation I'd give. - That's a really interesting point because I think all of us, sometimes whatever device we're using
from whichever manufacturer, they always say, oh,
would you like to update? You know, and all this. And we're like, oh, I'm busy. I don't wanna restart
things, et cetera, et cetera. But to your point, it's not just about, oh, there's been some shady behavior that's already occurred
and this protects you, but it's a big beacon to say, hey, in case you didn't
notice shady folks, these are ways that you might. So that's a really good time to update. What other things should I watch out for? - One of them is to only install
apps from trusted sources. So, on your iPhone, it
comes from the App Store, on your Google Android phone,
it comes from the Play Store. We test these on a continuous basis. The Google Play Protect scans billions of applications
and is continually updating to ensure that you're only getting things that have been vetted and that have gone through scanning. But if you're trying to
get something for nothing, or, you know, often is the case, your kids are trying to
get something for nothing and they find a free version of a game that's in some, you know,
dodgy corner of the web, this is kind of like
going down a dark alley and, you know, buying stuff from somebody with a trench coat on. You get what you pay for and what that might include
is viruses, malware, and hacking threats. - No, no, I agree so much with that because sometimes I've
looked for like, even a patch from a well known, you know, from some piece of software that comes. And I do it and some of
these shady actors actually have search results that are pretty high that they might be a paid
ad or something like that. And I'm not sure whether
they're necessarily but you realize that the person
claiming to provide a patch for a certain piece of software isn't necessarily the
publisher of that software. So I'm not saying necessarily that those are good or bad actors, but it is vary to your point, be extra careful you're
installing anything on a any kind of device
who it's coming from. - We built something at Google
called the Security Checkup really designed to be this one stop shop for all your devices, everything you've got
connected to your account. So there's a simple link
g.co/security checkup. And what that does is it runs through is your device protected
against local threats, you know, somebody grabbing it and just, you know , surfing your data, is it protected against online hacking, are you up to date with
patches and security issues, are you installing, you know,
apps from safe locations. Basically all the tips
that I would give somebody bundled together into this one stop shop, g.co/security checkup.
