Cyber ​​attacks are becoming common, so everyone is concerned about the safety of their data.

To prevent your passwords and other important data from being stolen, you should be aware of any changes to your computer.

In this report, the American Maximus website discussed the methods needed to find out if your computer is hacked, and how to deal with it.

Antivirus stop working

If you did not turn off the antivirus program but noticed that it stopped working, then most likely your computer has been hacked, as this program cannot stop working on its own, and the first thing hackers do is turn off the antivirus program to easily access your files.

The fan of the machine works more quickly

One of the simplest messages to know if a computer or mobile device has spyware, crypto-mining malware or other processing-intensive viruses, says Bill Siegel, founder of Coveware.

So if your phone suddenly needs to be charged 3 or 4 times a day, the fan runs more than half the time, and it's always hot in your pocket or handbag, this could be a sign that malware is running and burning more CPU power .

Passwords disabled

The site said that if you don't change your passwords but they suddenly stop working, and you can't open your accounts, your computer has likely been hacked.

New icons appear

When you launch your browser and notice new icons on the computer interface, this is a sign that some dangerous icons have entered your device.

Signs of a cyber attack not only appear on the computer itself, but also affect the printer, such as not responding to print commands or printing something you didn't ask to print.

The computer is very slow

If the simplest operations on the computer are taking a long time, or you notice a significant drop in your Internet speed, it may mean that someone has hacked your computer.
