Today we could not imagine our day to day without the Internet. We enter it several times a day (and at night), from our mobile, computer or other devices. We may need it to carry out our work or to inform ourselves, learn or as a form of leisure. Unfortunately, the digital world carries its own risks as well.
Hackers find security holes in our systems to access and steal our data. These 10 signs could indicate that your computer is being hacked:
- The computer starts to slow down for no apparent reason.
- It is always hot and the fans are constantly running .
- The webcam opens or records without prior notice .
- You see flashing lights when your computer is in sleep mode.
- Programs are very slow or “crash”, that is, they stop working as they should and do not respond. Many times what happens is that the program freezes and does not react.
- Your browser has extensions that you have not installed .
- The web pages you visit are filled with pop-up windows .
- Your home search engine has changed .
- You cannot access some websites that others can enter without problem.
- The antivirus opens pop-up windows for you.
How to prevent computer hacking
Here are a few basic hygiene recommendations against hacking. You should know that they do not guarantee that your computer is 100% impenetrable, that is impossible, but it can save you more than a scare. Here they go:
- Download a trusted antivirus that detects and neutralizes malware and blocks connections to malicious phishing websites (they pretend to be other trusted people, companies or services so you can share your passwords, card number, etc.). Keep the antivirus updated and also the operating system.
- Do not enter websites that are not secure and never download attachments without verification. Also, do not enter links in emails from unknown senders.
- No bank or online payment system will ask you in an email for your password, credit card or social security number. Ignore if you receive such an email.
- When you go to choose a password, it is better that it is long and complicated and that you do not use the same one for everything, because if it is hacked you will have access to everything. A good idea is to use a password manager, which helps you choose a strong password, reminds you of it, and alerts you if you are using it on too many sites.
