Don’t let these malware attacks eat away at your sense of security online. There are a number of red flags you can look out to help spot different malware threats. Malware attack warning signsKeep your guard up as you browse online by keeping these malware attack warning signs top of mind. Slower operating systemIf you notice a dramatic slowdown in your computer’s speed, that may be a sign malware found its way on your device. You may also notice screen freezing, unexplained restarts, and random Wi-Fi disconnects. Keep in mind, not all computers experiencing slower systems have malware infections. Sometimes a lack of storage can have an effect on your device’s operating system. Unexpected crashesSome system crashes have a root cause, like incompatible software or power issues. However, there are some instances where malware could be at play. If system crashes become constant, even with applications you know work for your computer, there is a chance it’s suffering from a malware infection. Pop-ups and security warningsPop-up ads annoy a lot of online users — which is why many browsers come with pop-up blockers pre-installed. That’s why if you see a flood of pop-ups come to your screen, you’ll know that they're likely ridden with malware. Hackers use these malicious ads and spyware to track your online activity. Ransom demandsRansom demands displayed on your computer screen are a sure sign that your computer has malware on it. Hackers use different types of ransomware to take advantage of a person’s private information to make a profit for themselves. Diminished storage spaceDramatic changes in your computer’s storage capacity could be a sign that your device is hosting dangerous malware. Little to no space could mean that malicious software was able to compromise multiple files, as malware expands as it goes deeper into your system. An excess of space may indicate that the malware was able to complete its work since some infectionscan delete important files and software. Suspicious network trafficA cybersecurity trick many people use is monitoring their network traffic for signs of suspicious activity. If you shut down all your connected devices and still see continued activity, a hacker may have snuck malware onto one of yourdevices. Browser redirectsThough not every redirect is dangerous, there are some browser redirects that could lead you to potentially harmful websites. For instance, hackers can create browser extensions designed to automatically redirect you to their malware-infectedsites. They’ll use these to collect and record your personal data. Knowing the signs of unsecured websites can help you identify this malware attack tactic. That includes watching out for:
Disabled antivirus softwareHackers are smart enough to know that most people equip their devices with some type of malware protection. Their workaround was designing malware that can disable antivirus software or other types of security extensions that alertusers of potential threats. If you find these tools disabled on your computer, check to see if your device shows other signs of infection, such as a slower operating system and limited storage space. Contacts receiving strange messages from youIf your friends start to ask you about strange messages you’re sending them (other than the occasional meme), then your personal phone number or email may be in the hands of a cybercriminal. Hackers might be using your trusted phone numbers and stolen contacts to send phishing emails and spam texts to your contacts. 6 malware protection tips
1. Update operating systems regularlyIt’s important to make a habit of checking your devices for software updates on a regular basis. As mentioned, hackers often use botnets and other types of malware to expose zero-day exploits to compromise your devices and network. 2. Beware of suspicious links and attachmentsKeeping an eye out for suspicious links and attachments may help prevent a malware attack from sneaking its way on your computer. These could look like URLs that don’t quite resemble what you’re used to seeing or email attachments from unknown senders. Cybercriminals love using these in addition to phishing emails and social engineering tactics to trick users into handing over their private information. 3. Consider an ad-blockerCyberthieves may use popups infused with spyware and/or adware to illegally track your network activity and install malware onto your device. To help prevent these kinds of malware attacks, consider downloading an ad- blocker. This cybersecurity tool helps keep malicious advertisements from appearing on your screen — and, in turn, keeps you from clicking on them. 4. Enable two-factor authenticationTwo-factor authentication comes in handy if a cybercriminal is able to access your login credentials. Biometric security features like fingerprint scanning and facial recognition make proving your identity a must before you can fully access your account. And since hackers probably won’t be able to replicate your DNA and/or facial structure, they’ll likely hit an obstacle to access. 5. Monitor your networkUsers can turn to their network activity to see if they’re potentially dealing with a malware infection. If you notice unfamiliar IP addresses taking up a large amount of your usage, a hacker could be trying to compromise the data on your devices. 6. Download antivirus softwareTrusted antivirus software could help provide your devices with 24/7 protection against the malware attacks threatening your Cyber Safety. Often equipped with password managers and threat detection software, security software could help you browse more confidently knowing you have the right cybersecurity tools working to keep you safe.
