You're browsing the net, wandering from one website to another and then you see a popup saying that your PC is infected with viruses... OMG! You're screwed!
No you're not. Read my lips... my post, YOU ARE NOT INFECTED! But if you click the link proposed in the screen, you might get infected... I'm dead serious!
As most of my readers are technology aware, it may seem obvious. This post is intended for moms, dads, aunts, grandpas and about 90% of the world population. Here's the truth, the whole truth and nothing but the truth...
Technically, a webpage cannot detect if you have a virus on your computer. Be it Windows, OSX or you Android device... It's totally impossible as no browser (the thing you used to go on the Internet) is not allowed to scan your computer in anyway. Makers of Internet Explorer, Firefox or Chrome have not provided any kind of special access to read your folders, your memory or your Facebook accounts.
The only way a browser could do more than it was intended to do is if you have installed a plugin from an unknown source, that promises some technological miracles... You know, "Download Faster" or "Plugin Required to view the video...". The only plugins you need to browse the net are Flash and Java and that's about it. Nothing else is required in any way.
So when a windows popups up, saying that some virus or trojan has been detected, close everything! That's right! Simply close everything to avoid getting infected.
A few simple rules:
- A webpage cannot scan your hard drive
- A webpage cannot detect your computer's performances
- Facebook will not shutdown your account if you do not share
- Twitter will not ban your account if you do now retweet
- The FBI does not have any report about the content of your hard drive
- The free cruise is a scam
- Your bank will never ask for your password to validate your identity
- Reset your password only from the official page (Facebook, your bank, etc...)
- Never trust a link in your emails
Why would you trust a webpage ad anything more than a stranger knocking at your door?
Share this post around with your friends, your family and make sure they understand that the real danger is them, clicking blindly.
Have a good day!
