If you think your computer might be hacked, knowing the signs is key. Seven common signs include seeing lots of pop-up messages, getting many emails from your account, and finding new programs you didn’t install. You might also notice changes to your passwords, slow computer speed, weird changes in your web browser, or strange webcam activity.
Spotting these signs can help you figure out if your device is at risk. Look out for pop-ups that seem fake, programs you don’t know, and odd network activity. These could mean your computer has been hacked.
Key Takeaways
- Frequent pop-up messages and mass emails from your account can signal a hacking incident.
- Unexpected programs, password changes, and browser modifications may indicate unauthorized access.
- Slow computer performance and strange network activity could be signs of malware infection.
- Missing or modified files are also potential indicators that your device has been compromised.
- Staying vigilant and taking proactive cybersecurity measures can help prevent and detect hacking attempts.
Unusual Pop-ups and Advertisements
Seeing lots of suspicious pop-ups, fake antivirus messages, and unsolicited ads on your screen could mean your computer is in trouble. These annoying elements often show that malware has infected your system. Criminals use them to trick people into downloading bad software or making money from fake ads.
If you see more of these pop-ups, it might mean your computer is under attack. Adware, a type of malware, can make your device show unwanted ads. This could lead to security problems. So, if you notice more pop-ups, it’s time to act fast.
- Pop-ups and ads could mean you have adware, a malware type that makes money for attackers.
- Adware shows ads on devices, making them more vulnerable to security risks.
- If you see more pop-ups and ads, check your computer for viruses to find any infections.
- Remove malicious software quickly to keep your device safe from more cyber threats.
“More than one-third of data breaches involve phishing, as per the Verizon 2022 Data Breach Investigations Report.”
Noticing suspicious pop-ups, fake antivirus messages, and unsolicited ads can alert you to a malware infection. This can help you protect your computer and personal info.
Slow Computer Performance
If your computer starts to run slow, with long startup times and slow program loading, it might have malware. Malware and other malicious software can tax your computer’s resources, leading to noticeable performance issues.
These issues suggest your system is overwhelmed by unwanted processes or applications. Often, this is due to malware infections. Malware uses up a lot of system resources like processing power, memory, and storage. This leaves less room for your regular tasks and programs.
- Frequent crashes or unusually slow computer performance can be symptoms of a compromised computer.
- If you notice a significant decline in your computer’s speed and responsiveness, it’s important to investigate further and address any potential malware or unauthorized activity.
For UTHSC-owned devices, the university must look into any breach of personally identifiable information. For personal devices, it’s wise to act quickly to protect against threats if you see slow performance.
Students should use Microsoft Defender for Windows or other security tools on the OIT Software Distribution Site. This helps keep their devices safe and running well.

| System Freezes | Frequent instances of your computer freezing or becoming unresponsive, potentially due to malware or unauthorized activities. |
Unfamiliar Programs and Files
Seeing strange apps, toolbars, or files you don’t know can mean someone might have accessed your computer without permission. Cybercriminals often put on harmful software or “potentially unwanted programs” (PUPs). These can watch your actions, change your web searches, show annoying ads, or bring more malware. These unfamiliar programs might have been put on your computer without you knowing, which could mean someone is hacking into your system.
If you see new files or programs you didn’t put there, be careful. Hackers might use these to get into your system, get unauthorized access, and take your private info or do more bad things.
- Check the apps and files on your computer often and delete any you don’t recognize or seem off.
- Make sure your operating system and software are current to lower the chance of hackers finding weak spots.
- Use good antivirus and anti-malware tools to find and get rid of any bad programs on your system.
By being alert and taking steps to keep an eye on your device, you can lower the risk of hacking and keep your private data safe from unauthorized access.
Unauthorized Network Activity
Unusual spikes in your network data usage could mean your computer has been hacked. Hackers might turn your device into a part of a botnet. This lets them use it to talk to a remote server and do bad things. You might see more data moving in and out of your computer than usual.
Keep an eye on how much data your network uses. If you see sudden, big jumps in data use, it might mean your system is hacked. This could mean your computer is part of a botnet or talking to hackers’ servers without you knowing.

Seeing missing or changed files is a red flag that your computer might be compromised. Hackers could delete vital system files or tweak your documents to hide their tracks or mess with your work. It’s key to watch your files closely and check out any sudden changes to stop more harm and keep your data safe.
Look out for these signs that might mean someone has accessed your computer without permission:
- Files or folders that have been deleted or moved to unexpected places
- Changes in file sizes, last modified dates, or who owns them
- New, strange files or programs showing up on your system
Dealing with these problems quickly can keep your computer running smoothly and reduce the chance of data leaks. By keeping an eye on your files, you can spot and fix any signs of a breach fast. This helps keep your important info safe from those who shouldn’t have it.

“Cybersecurity is not just an IT issue, it’s a business issue. Every organization and individual must take it seriously.”
Ransomware Messages
Seeing a ransomware message on your computer is a scary sign. Ransomware is malware that encrypts your files and demands payment to unlock them. If you don’t pay, you could lose your important data forever.
Ransomware messages show a countdown timer, telling you to pay fast or lose your files. They threaten to leak your private info or lock you out for good.
Many people pay the ransom to get back their files, but it’s not advised. Paying doesn’t ensure your data will be unlocked, and it encourages more attacks. It’s important to act fast when you see a ransomware message to lessen the damage.
