Hacking Signs: How to Tell If Your Computer Is Compromised

Signs Your Computer Has Been Hacked!

Someone used one of your credit accounts. Online identity theft is common. If you use credit cards online, that could be an indication a hacker was the culprit.

You start receiving odd email messages. Friends start telling you they’ve received strange emails from you (that you never sent), or you notice messages in your Sent folder you didn’t write…these are clear signs a hack has likely happened.

New programs suddenly appear. You didn’t buy it or install it, but you notice a new program has been loaded onto your computer. That’s a clear indication that someone has manipulated your computer.

A trusty password doesn’t work. If a password suddenly stops working, that could mean a hacker has broken into your computer and changed your account’s login details—and it could get worse from there.

You notice strange browser activity. Some hackers move right into a computer and control it as if they’re in front of it. Often, this involves exploiting and hacking IP address details to gain unauthorized access to your network. If you ever notice browser activity that isn’t yours (or someone else’s in your family), that could mean trouble.

You start losing control. A computer virus can redirect your browser activity and prevent you from reaching websites you want. That’s certainly the work of a hacker who came and went.

Here are more possible signs that a hacker may have successfully targeted your computer:

You can’t update your system. Malware, which may have been put there by a hacker, can prevent you from downloading the latest system or antivirus updates.

Your computer runs slower than usual. Internet connectivity has gotten better over the years, so if you notice your connection slowing down, it’s possible there’s someone using your bandwidth—it could be as simple as someone using your unsecured wireless connection or as bad as a stealth hacker downloading data from your hard drive.

A big-name company was hacked. You read that Target, Home Depot or FitBit was hacked…so what’s the big deal? Well, if the hackers got email addresses and passwords, they’ll immediately test that login information elsewhere. A hack could be coming, which is why it would be wise to change your passwords immediately.

You notice unusual disk activity. If you hear your computer hard drive whirring overtime, it could be your antivirus software scanning—or it could be hacker-placed malware looking for data to damage or steal. Look into it.

Your antivirus software becomes disabled. There is malware out there that hackers use to 1) disable your antivirus and 2) create havoc. If you notice your antivirus turns off on its own, there’s a hacker at work.

Strange things are happening onscreen. Except for annoying, intrusive online ads, there shouldn’t be too many onscreen surprises. If you see strange things—toolbars, pop-ups, new programs you didn’t have before—it’s likely you’ve been hacked.

Frequent random pop-ups: This is one of the most explicit indications of a computer being infected. If you start seeing more annoying pop-ups in your web browser, and they often flash in sites that usually don’t generate pop-ups, this is a bad sign.

Here’s what to do (immediately) if your computer has been hacked:

Run a full virus scan to detect the malware and viruses infecting your computer

Review the applications installed on your device. If any developer or vendor doesn’t seem legitimate, uninstall the app right away.

Change the passwords for your online accounts.

Then, alter your online behavior (if necessary) and get into better safety habits to enhance your security:

Use a VPN to browse the Internet privately and securely.

Wherever you can set two-factor authentication for important online accounts.

Use a password manager to keep your passwords secure.

Clear browser cookies regularly.

Never click on suspicious links nor download applications from unknown sources.

Here’s an even better idea.

Don’t wait to get hacked before taking all of the above “reactive” steps. Instead, consider implementing all of the steps to boost your security now.

You know what they say…the best defensive is a good offense.

Start by learning how to be safer online by using a VPN like NordVPN to hide your IP address.

Here’s the point to all of this: If you’re lucky, you’ve never been hacked. Or is it that it’s already happened, but you’re not aware of it?

That’s why it’s important that you know what to look for. So, if you now suspect you might be the victim of some computer foul play, you should go online for tips and remedies for setting things right.
