But how can you tell if you’ve been a victim of a malware attack? There are several telltale signs your device may have a virus. We’ll share those red flags and outline steps you can take to get rid of the virus, and provide some tips to help protect your connected devices in the future.
How to tell if your computer has a virus
A computer virus is a type of malware that infiltrates a computer and its programs. It’s similar to the way the flu infects your body’s immune system and multiplies. Viruses can be installed on your computer without your knowledge or consent, and can insert new, malicious code that can monitor and manipulate your online activity.
Some malware may not seem serious, but they coud lead to more damaging problems. For example, criminals could use a virus to access to your personal information which could enable them to commit identity theft and other types of fraud.

You may be thinking you couldn’t possibly be affected. Or perhaps you’re wondering how bad a malware infection could be. The answer? Quite bad. For example, the MyDoom virus, discovered in 2004, is considered the most damaging virus ever released. Not only was MyDoom the fastest-spreading email-based worm, but it caused $38 billion in damage.
Ransomware is a another kind of virus that poses a threat. Ransomware entices its victims to click on a legitimate-looking link in an email that contains malicious code. The malware then prevents you from accessing your data by encrypting it. It holds that data hostage until you pay a ransom.
One example of ransomware was the destructive WannaCry virus of 2017, which targeted systems running Windows OS. Victims were asked to pay ransom in anonymous payment systems such as Bitcoin in order to retrieve their data. Keep in mind, even if you pay, you may not get your data back. That’s one reason why it’s recommended you shouldn’t pay the ransom.
Computer virus warning signs
Computer viruses are about as diverse as computer users. There could be thousands of new viruses and malware attacks each year and they can affect devices and operating systems in many different ways. But several virus warning signs tend to be similar across the board. Here’s how to tell if your computer may have been infected with a virus.
![Mac Mac](https://www.gflesch.com/hubfs/images/Email Header CTAs/EMAIL-7_Hacks_Infographic-1200x600.png#keepProtocol)
1: Major slow down of your computer’s performance
Are your files and apps taking a long time to load? Is your computer taking a longer time to start and runs slowly once it does? If so, it’s possible a virus is infiltrating your operating system.
2: Endless pop-ups and spam
Frequent and odd pop-up windows are a red flag. Pop-ups might prompt you to visit other websites to download antivirus or other software programs, which instead may install malware. Malicious pop-ups and spam could also secretly install spyware that could hijack your browser or steal your passwords and other personal information without your knowledge. When you finally catch on, it might be too late.
3: You’re locked out of certain settings, files, folders or your entire computer
If you’re unable to gain access to settings and files on your own computer — or you can’t log on or off — malware has likely taken over.
4: Changes to your homepage
Is your homepage randomly switching to another website? Are you unable to reset it? If so, you likely have a virus. Viruses can implement changes to your homepage and create error messages, browser errors and shortcut files.
5: Unknown programs start when you turn on your computer
Computer viruses can create widespread problems. Adding icons and toolbars that you didn’t set up is just the tip of the iceberg. If unknown programs load when you turn on your computer or other connected device, turn it right off again. You’ve been infiltrated.
There are different ways to find out what programs are running on your computer. On Windows machines, for instance, Task Manager is a utility included in Windows that shows you what programs are running on your computer. On a Mac you can find this in Activity Monitor.
6: Mass emails sent from your email account
Have you ever received an odd email from a friend that made you suspect someone hacked into their email account? Or you see people on Facebook and other social media platforms tell everyone they’ve been hacked and not to accept friend requests? If your email’s ‘Sent Items’ folder contains messages you didn’t send, your social media accounts have posts you didn’t make, or you can’t log into your email or social media accounts, your email and other accounts most likely have been compromised.
7: Your security software has been disabled
If your antivirus program or security software has stopped working and you didn’t disable it, it’s possible that malware has taken over.
8: Your battery drains quickly
Here’s another sign that a virus may have infected your computer and is multiplying: a drained battery. As the virus continues to multiply, it uses resources from your computer and creates more activity on your computer. As a result, your battery life is diminished.
9: Frequent crashes
Does your computer randomly crash on you? Does your screen freeze and become the infamous “Blue Screen of Death”? This is a could be a sign that your device has been infected with a virus.
What to do if your computer has a virus
You can take several steps if you suspect your computer has been infected. To start, you could get rid of the virus manually yourself. You likely will need to do a web search and perform a long list of steps to find out what’s really going on. Unless you’re an expert, it can be complicated.
A simpler approach is to install an antivirus software program from a reliable company. You can let the professionals do it for you to ensure you’re not leaving your computer open to any vulnerabilities. An antivirus program, also known as security software, may also scan your external hard drive when it’s plugged in, but keep in mind not every program checks the hard disk.
But when you do this, be sure you aren’t buying a program in response to an unexpected call or message. This could be a trick to download more malware.
Instead, go to a secure website that you trust. For example, a reliable security software is Norton Security, which can remove many viruses and help protect your Windows PC, Mac, Android and iOS devices against future infiltrations. Norton recommends a three-step virus clean-up plan:
Step 1: Run a security scan
You can start by running a free Norton Security Scan to check for viruses and malware.
Step 2: Remove existing viruses
You can then remove existing viruses and malware with Norton Power Eraser. It will perform a scan and give you onscreen instructions. If needed, you can call Norton for technical assistance. After following the instructions, restart your computer.
Step 3: Update security system
The most important thing you can do to help protect your devices against viruses and threats is to make sure your computer’s software is updated with the latest protections. When you’re notified of a Windows update or web browser update, for instance, it’s a good idea to install the latest version right away.
Then set your security software, web browser and operating system (such as Windows or Mac OS) to update automatically. This helps keep your operating system up-to-date and ready to detect and handle the latest viruses.
Once you’ve updated your software and secured your device with security software, there are simple and practical steps you can take to protect yourself, including these.
- Reset the passwords to all of your accounts — and make sure they’re strong by including upper and lowercase letters along with numbers and symbols. Each account should also have its own unique password. A password manager can help you track and manage multiple passwords.
- Use a pop-up blocker and be sure not to click on any unknown links or attachments.
- Only download from sites you trust. Never download free, software onto your computer, because it may be malware in disguise.
The bottom line? Don’t make it easy for cyberthieves to infiltrate your computer. Instead, keep an eye on your computer activity, be cautious about your own activity, and ensure you’ve updated your antivirus software and operating system with the latest protections.
It’s like wearing a mask or washing your hands during cold and flu season. Viruses may float around, but you’ll be helping to protect your system so they have a lesser chance of infecting you.

Smart hackers don’t get caught. They break into your device, steal everything they can, and finish without a trace. Sometimes they leave a trail of destruction in their wake – malware, weird ads, confused relatives, and even a drained bank account or stolen identity.
It’s pretty easy for hackers to do their job. Most people are ambivalent, but you don’t have to be. Click here for 5 security mistakes you’re probably making right now.
Computers, phones, routers, and down to the innocent webcam are vulnerable to cyber-criminals. So what if they’ve already broken in, yet you don’t even know they’re there? Here are clear-cut signs that you've been hacked.
1. Your gadget suddenly slows down
One of the side-effects of malicious software is a slow gadget. Software gets sluggish, or constantly freezes, or even crashes. If you start noticing some of these symptoms, your gadget may very well be infected with viruses, trojans or worms.
Malicious software usually runs in the background, secretly eating up your gadget's resources while it's active.
Here are tools you can use to pinpoint those nasty applications. If an application that you don't recognize is hogging your computer resources, it's likely a virus.
PC: Use Task Manager
There are a few ways to see what processes your computer is running. The easiest is to bring up Windows' built-in Task Manager. Just use the keyboard shortcut CTRL + SHIFT + ESC and go to the Processes tab.
Put simply, the Task Manager lists all of your computer’s current tasks and how much processing power they’re using, measured in Central Processing Units (CPUs). Open up Task Manager and check the CPU and memory columns for each process.
You might find one process is using 100% — or close to it — of your CPU. Open up the program associated with the process and see what it's doing. Restart the task and monitor it, but this program might be the culprit.
Click here to learn powerful Windows Task Manager secrets for diagnosing and repairing slow computers.
Mac: Use Activity Monitor
The Mac equivalent to Task Manager is its built-in Activity Monitor. The quickest way to access the Activity Monitor is by using Spotlight Search.
Click the magnifying glass on the right side of the menu bar at the top of your screen, or press Command + Spacebar to open a Spotlight window and start typing the first few letters to auto-complete 'Activity Monitor.' Just press Enter to access the tool.
I Have Been Hacked
Similar to Window's Task Manager, Mac's Activity Monitor displays a list of all your open processes with tabs for CPU, Threads, Idle Wake Ups and Network usage.
Learn these three troubleshooting Mac shortcuts the pros use.
If this happens when you are on an iPhone, try a soft reset by holding the power and the home button until it reboots with the Apple logo. This step can clear out frozen apps that can be hogging your memory.
2. You’re using way more data than usual
Every Internet provider has tools that can keep track of your monthly bandwidth consumption. Look at Data Usage Meter or Data Monitor, depending on your provider. Compare the amount of data used from the prior months, and if you notice sudden spikes in your data activity even though you haven't changed your patterns, then chances are you are infected.
For example, adware infected gadgets usually perform unsolicited clicks in the background to generate profit for cybercriminals. These stealthy tactics use up bandwidth and the unauthorized data they consume should be fairly easy to spot.
Do you want to save on your data consumption? Here are 5 steps to cut your data usage in half.

3. Videos suddenly buffer and web pages take forever to load
When a streaming video suddenly freezes, and your device appears to be “thinking,” this is called buffering. This annoyance often happens, especially if you play a lot of videos or your Wi-Fi connection is weak. If it’s happening a lot, or videos fail to play at all, you’re wise to suspect neighbors are piggy-backing on your connection. Click here for steps on how to check for Wi-Fi thieves.
Then again, malware can also slow down your Internet traffic by DNS hijacking. In short, hackers can redirect your Internet traffic to unsafe servers instead of the secure servers. This will not only slow down your browsing experience, it's also a serious security risk. For example, if your router's DNS settings have been hijacked, each time you visit your online bank's website, you'll be redirected to a phishing website instead.
To check your router's DNS settings, you can use an online tool like F-Secure Router. For more security, consider changing your DNS server to one with advanced hijacking protection like CloudFlare or Quad9.

4. Programs and apps start crashing
Now, here is a clear sign that your system has been infected. If your antivirus software and task manager are either crashing or disabled, a nasty virus has likely taken hold of your critical system files.
You may not be able to click on once-reliable apps. In the worst case scenario, ransomware may prevent you from opening favorite files.
You can try and fix the problem by booting your gadget in Safe Mode. With Safe Mode, your computer will be running with just the bare essentials. This way, you can safely delete and uninstall any programs and files that you can't during normal operation.
Windows:
On Windows, search for System Configuration then open it >> select Boot tab then tick off Safe Boot >>check Minimal (this is enough for most cases) >> click on OK to confirm >> Restart your computer.
Click here for detailed steps on how to boot into Windows Safe Mode.
macOS:
On a Mac, press and hold down the Shift key while restarting your computer. Keep holding the key through the Apple logo and release when you see the login screen.
Android:
Android also has its own version of Safe Mode but there are different ways to activate it, depending on your phone model. Click here to learn how.
iOS:
Stock iOS doesn't have a Safe Mode but you can try a soft reset to fix most issues. To do this, press and hold both your iPhone's Home button and the Sleep button at the same time, wait for it to restart then let go of the buttons when the Apple logo is displayed.
The iPhone X doesn't have a Home button so the process is a bit different. Press and quickly release the volume up button, press and quickly release the volume down button then press and hold the side button and release when the Apple logo appears.
5. You start seeing pop-up ads
Malware can also add bookmarks that you don't want, website shortcuts to your home screen that you didn't create, and spammy messages that entice you to click through. Apart from slowing down your gadget and eating away at your data, these intrusive notifications can also install more malware on your system.
Criminals can also use DNS hijacking to modify the ads that you see while browsing. Instead of the regular ads that you should be getting, they can be replaced with inappropriate or malicious ones.
On Windows, clean out adware with SpyBot Search & Destroy. On a Mac, use Malwarebytes for Mac.
6. Your gadget suddenly restarts
Automatic restarts are part of normal computer life. Software updates and new application installs can prompt you to reboot your computer. Your system will warn you when these happen, and you can delay or postpone them.
Yet sudden restarts are a different story. With Windows 10, there's a free malware detection and extraction program called Microsoft Windows Malicious Software Removal Tool.
I recommend a Full Scan with this tool to verify that your computer is updated with the latest malware definitions.
7. Unexplained online activity
How To Know If Your Mac Has Been Hacked
Hackers covet your usernames and passwords. These details, coupled with social engineering tricks, can gain access to your banking accounts, your social media profiles, and your online services.
Keep an eye on your email's 'sent' folder and on your social network posts. If you notice emails and posts that you don't remember sending or posting, it's likely that you have been hacked.
Constantly check your accounts for unauthorized activity including movies on your Netflix profile that you don't remember streaming, mystery purchases that you haven't made, songs on your Spotify list that you didn't listen to, credit card charges that came from nowhere.
