How To Tell If My Computer Has Been Hacked


In present times, it is an undeniable fact that hacking and cybercrime are on the rise. It has been estimated that hackers attack someone online every 32 seconds. The question is “How To Check If I Have Been Hacked”.

While cybercriminals will continue to find new methods to infiltrate your devices, there are ways to remain vigilant and aware of your computer’s security status. No one is asking to be hacked, of course, but it’s an unfortunate reality for everyone.

How To Check If I Have Been Hacked

However, if this happens to you, here’s how to tell if your computer has been hacked and how to stop hackers in their tracks.


  1. Denial-of-service attack

You can tell that a denial-of-service (DoS) attack occurred when your password seems to have randomly changed for an account or device. Another indicator is if you can no longer access key system settings, such as a factory reset or system restore option. A DoS attack can sometimes culminate in a ransomware attack, which means a hacker will attempt to hold your sensitive stolen data ransom. listed below are 4 additional steps you can take to prevent a DoS attack.

  • Check your online account settings

    You can stay ahead of hackers by keeping an eye on your online accounts to see if there are any recent changes. It’s easy to overlook this step, especially if you don’t use a particular account often or you don’t look at your own page frequently, in Facebook for example. It’s worth doing, though, because social media sites allow you to lock down your account in your account settings tab if you’re worried about suspicious activity.

  • Enable two-factor authentication

    Two-factor authentication makes it more difficult for hackers to access your account and adds another layer of security, even if someone steals your password. This adds your phone number or an authenticator app to your log-in process, which means the hacker would need access to your phone as well as the original account.

  1. Fake Antivirus Software Messages And Pop-ups

Malware is often at the root of fake antivirus messages and other unwanted pop-ups on your PC. If you see random pop-ups on your screen, do not click them. Instead, close your browser and start it again in incognito mode and reload the page.

Then, check your computer’s antivirus program, firewall, task manager, and registry to make sure they’re not disabled or altered in any way.

It’s important to never download any antivirus software that you have not thoroughly researched and vetted. If it seems illegitimate, it probably is, and it may lead to malware landing on your PC.

  1. The Dreaded Trojan Attack

Fake antivirus software may also serve as a Trojan. If you installed a fake antivirus program by mistake, your operating system may view it as a trusted program. Your OS then won’t stop you from downloading anything else nefarious initiated by the Trojan.

If you fall victim to a Trojan attack, there are steps you can take to mitigate it. First, you need to format your hard drive, which may be painful if you haven’t backed up your important data. For those who may not be up to date with this critical maintenance task, check out our list of the best Windows backup software to be prepared.

If you can’t format your drive, you can stop the threat by downloading a malware removal tool from a non-infected device. Then connect it to your infected system via a USB flash drive. In many cases, this will remove the fake antivirus software without damaging your PC.

  1. Browser Toolbars And Search Redirection

There may be times when your browser of choice inexplicably loads to a homepage you’ve never seen before. If you made this change by accident, it’s easy to fix. But it may actually be a sign that you’re the victim of a virus that is actively redirecting your browser.

Hackers typically do this as a way to serve you ads. They may even potentially redirect you to a mirror of Google that earns them ad revenue every time you search. To get rid of this, remove any installed third-party browser add-ons, extensions, and toolbars you don’t recognize.

You should also change your browser back to the default homepage and remove any unwanted search engines from your tools. Then, restart your PC in Safe Mode and make sure the browser works according to your preferences. If not, your system is likely infected with deeper malware and you will need to run an antivirus scan to fix the issue.

If you notice anything wrong with your PC, immediately check for things that have changed, especially whether any programs or applications were installed without your consent.

Once it has been identified, you should be able to solve it by troubleshooting the issue with the steps above. Then, take the time to put some basic cybersecurity measures in place so it doesn’t happen again.
