This episode is "antivirus".
[music introduction] Okay, I'm always asked about beingprotected online.
The producer of this show thought it'd be a good idea to bring up antivirus,and what would happen if she had two copies of antivirus running on her server or computerat the same time.
Here's my take on antivirus: I think everyoneneeds to have antivirus, and there's a couple different companies out there.
I can't suggestone, because whatever I say, someone else is gonna tell you something different.
We all have our own favorites.
Here's what to think about: are the free onesactually providing enough protection? Are the paid ones costing me money to protectsomething that I don't need? And can I run two on my computer, in case I want to be extrasafe? So here's how it works.
When you're runningtwo antiviruses together, let's just suppose I'm going to use two free versions, when theyinstall they're both doing a thing called "active scanning".
When you download a file,as soon as that file's done, antivirus starts to scan that file; that's active scanning.
You don't have to do anything, it's doing it for you.
If you have two versions of antivirus on yourcomputer, and they're both active scanning, then what happens is once the file is downloadedtwo different softwares try to scan the file at the same time, leaving less-than-desirableresults.
Actually, it could corrupt the file and couldprobably harm the OS, depending on what you're downloading.
Think about it this way: when you get theflu shot, you are getting the flu definitions.
And what that's doing is letting your bodystart to fight against that so that if you do get that virus, your body already knowshow to handle it.
Look at antivirus as the same way.
Antivirus uses definitions to combatthe viruses coming in.
If I install two versions, they should havetheir own definitions.
This virus might think that these definitions are the virus.
So thetwo actually kind of cancel each other out.
You're doing more harm than good.
So stick with one choice of antivirus, whateverit is that you wish, get the full version.
And there's other things you can do to keepsafe.
One, make sure your operating system is alwaysup-to-date.
If you have a Microsoft operating system, Microsoft offers online updates.
Ifyou're running Windows 10, that actually is not an option for you, it does it automatically.
Two, make sure your virus definitions areup-to-date.
'Cause even if you bought the antivirus, your definitions are updated asthe manufacturer finds the new threats.
And three, run a firewall of some sort.
Allof Microsoft operating systems, from XP Service Pack 3 all the way up to the latest release,which currently is 10 in the desktop version, has the firewall protection built in.
If youhave the firewall turned on, your antivirus up-to-date, and your operating system up-to-date,you're gonna be safe on the Internet.
As long as you don't do something silly andsay, "Oh my God, I just got an email saying I've won a million dollars in the Australianlottery!".
Don't click the link! Another tip is to do something to help combatmalware.
These are little tools that get in that antivirus doesn't necessarily hit, becauseit's not a virus, it's more of an advertising network that delivers ads to you, probablyunwanted.
Some tools to think about are ADW Cleaner,Spybot Search & Destroy, and Malwarebytes.
All can be found in the notes in our show.
You can also pick up a handy little tool calledCCleaner that cleans your temporary files where most of your viruses build.
