12 — The antivirus is switched off

Antivirus programs are pretty hard to disable, even when you want to. They have special safety protocols that ask you two or even three times if you are sure that you don’t want the program to work.

So it’s almost impossible that you turn it off accidentally. The first thing that good hackers do is disable the antivirus, so that you can’t detect the intrusion.

But you are smarter than them, right???

- So as soon as you notice that your antivirus is off, turn it back on and contact a specialist.

11 — You receive fake antivirus warnings

If you see antivirus warnings that look different or unusual, this is a clear sign of a hack. Another bad sign is if you have a new antivirus you didn’t install.

However before you start to worry, check if your old antivirus software was updated. Maybe it just looks different now.

10 — your passwords don’t work

If you can’t access some of your accounts, and you’re sure you didn’t change your passwords and forget about it, your computer has most likely been hacked.

Fortunately, most services have the two-factor authentication, so you can restore your passwords by having a code sent to your phone number.

Once you’ve done it, change passwords even for the accounts that apparently haven’t been hacked yet. Tell all your friends not to open messages from you, and not to go through the links sent from your accounts.

9 — Your number of friends has grown

If you see some people on your social network pages that you don’t know, and there are many of them, it’s a clear sign that your computer, or at least your account, has been hacked. Check the chats with your friends for spam messages.

8 — New icons appear on your dashboard

When you launch your browser and notice new icons on your dashboard, this might be a sign of the infiltration of some dangerous code onto your computer.

Don’t run unknown applications if you don’t want to make the hackers’ job easier. Try to delete them from your computer if you can.

7 — The cursor moves on its own

If you notice that your cursor is moving without your control and is highlighting something, it means your computer has definitely been hacked. Someone is probably doing something at this very moment.

What you should do is disable the internet connection as soon as possible. Of course, after you finish watching this video, and like it.

This means disconnecting the ethernet cable or turning off your wireless router until a specialist arrives and fixes the problem.

6 — Your printer doesn’t work properly

You might be surprised, but cyberattacks influence not only the computer itself, but also your peripheral devices.

For example, if your printer refuses to print something out, it might be a worrying signal. Or, you’re just out of paper. Who knows? The same applies for all other devices connected to your computer.

5 — You are redirected to different websites

You should be alert if your browser keeps redirecting to different websites. Of course, maybe it’s your own fault.

Do you remember visiting some suspicious-looking internet sites?

If not, your system might have been hacked. It’s time to call a specialist if you type something into a search engine and instead of Google pages, you go to another page you don’t know.

The same goes for situations when you see too many pop-up windows.

4 — Your files are deleted by someone else

This is a 100% sign of a hack. If you see that your folders are empty, don’t panic. There are some tools that can restore deleted files, so this is not the most pressing issue. But the safety of your system is.

3 — Your data is on the Internet, even though you didn’t put it there

You’ve probably heard many stories in the news about celebrities whose photos were stolen and shared with the entire world. This is a terrible situation to be in, and this can happen to anyone.

It’s just that only celebrity stories end up in the newspapers. Hackers can start blackmailing you, threatening to share your information with your friends. YOUR NEXT First take care of your credit cards.

Call your bank and tell them to block the cards that you have used to pay for something online. Only after your money is safe, call a specialist that can deal with the safety problem.

The stolen data can’t be returned, so whatever is online stays online. Try not to store files you don’t want to be stolen from your computer.

2 — There is unusual webcam behavior

Check your webcam indicator. If it is on or blinking, make sure no applications are launched that require a webcam, such as Skype, FaceTime, or others.

If you don’t see a reason for the webcam to be on, reboot the system and check again. If the indicator is on again, you have a problem. Disconnect from the internet and call a specialist.

1 — Your computer works very slowly

If even the simplest operations take your computer a very long time to complete, and if you notice a significant drop in the speed of your internet connection, it might mean that someone hacked your computer.

First, try to reboot your computer and check the performance again. Maybe you just need a hardware upgrade. If nothing changes, launch the task manager and look for the processes that are eating your RAM.

Shut down all tasks that you can and see how well the computer works. If you experience problems after that, well, you already know what you should disconnect, and who you should call.
