Malware warning: Red flags your computer is under attack

It’s Computer Security Day, and there’s no better time to remind you malware is lurking everywhere. From phishing emails to unsuspecting ads, just one wrong click can compromise your personal info or infect your devices.

Don’t panic! Knowing how to spot the early warning signs can save you a world of trouble. Let’s make your devices malware-free zones.

I saw the sign … and it slowed down my computer

🚩 Sluggish performance: Does your computer seem like it’s running so‑o‑o‑o slowly? Most malware hogs your system’s resources. Start by checking for too many open tabs or outdated software. Still slow? It’s time to dig deeper.

🚩 Pop-up pandemonium: Random pop-ups are a big red flag. They might be ads or flashing warnings saying your system’s infected. Rule No. 1: Don’t click them. That’ll only lead to more trouble.

🚩 Mystery programs: Malware can lead to other sneaky software installed on your device. Go through the apps installed on your computer, phone or other device, and look for anything unfamiliar.

🚩 Hijacked browser settings: Did your homepage or search engine suddenly change? It could be malware trying to redirect you to sketchy sites. Fix this by removing any extensions and changing the default search page in your browser.

🚩 Disabled firewall: If your firewall turns off mysteriously, malware might be covering its tracks. To check your firewall settings:

  • On Windows: Go to Settings > Update & Security > Firewall & network protection.
  • On Mac: Go to System Settings > Network > Firewall.

🚩 Skyrocketing data usage: A sluggish connection or unexplained data spikes could mean your machine is sending data to who-knows-where. To check:

  • On Windows: Open Task Manager > App History and look at the Network column.
  • On Mac: Open the Activity Monitor app > View > Dock Icon > Show Network Usage.

Don’t wait for the worst to happen

🚨 Netflix renewal scam: Cybercriminals are sending fake Netflix texts claiming your account’s about to be suspended. They’ll say there was an “issue processing your payment” or a “failure in your recent payment” and ask you to sign in through a link. It’s just a trick to steal your login details and credit card info. Don’t fall for it.

3 billion-plus

Phone coordinates collected and sold by data brokers. The kicker? They expose U.S. military and intelligence workers, including people who work in places like nuclear weapons facilities. Anything for a buck.

Text-raordinary mistake: RCS messaging makes texting between an iPhone and Android device better, but there’s a catch: These messages aren’t encrypted. Google Messages is encrypted for Android-to-Android, and Apple Messages does the same for iPhone-to-iPhone texts. Between Android and iPhone? No encryption, meaning it’s super easy for a hacker to see your texts.

iScam, you scam: Cybercriminals are sending fake emails claiming your Apple ID is suspended, urging you to click a link to “verify” your info. Don’t fall for it. Apple never asks for sensitive info via email.

Russian hackers at work: They exploited two security flaws in web browsers Firefox and Tor to plant malware. Mozilla and Microsoft patched the issues, so update ASAP. Restart your browser (or browsers), then, in Windows, go to Start > Settings > Update & Security > Windows Update and hit Check for updates.

📶 Let go: D-Link’s VPN routers have hit their end-of-life, making it an easy way for hackers to enter your network. No security patches are coming. If cybercriminals get in, they can spy on your activity and steal your passwords or credit card info. Unsure if you’re affected? Contact D-Link.

🚨 Use Gmail, Outlook, Apple Mail or Yahoo? No joke, three out of every four Black Friday-themed emails are scams. The scammers’ goal? To steal your credit card info or plant malware. Brands most impersonated include Amazon, Shein and Costco. Stay safe: Always double-check the sender’s email address (not just the sender’s name) before you click.

You heard it here first: In May 2023, I told you about TSA’s facial recognition program. Basically, you look into the camera and it takes your pic to verify you. Now, some senators are saying the TSA wants it mandatory in over 430 airports, but we don’t know where this data is going or how it’s protected. You can opt out: Step back from the camera, politely tell them you decline facial recognition and present your ID instead.

Another scam heading our way: Cyber authorities in Switzerland are warning about malicious QR codes being sent through snail mail. Fraudsters are urging people to scan and download a new Severe Weather Warning app, but it’s actually malware. Once installed, hackers can take over your phone, steal info from your banking apps and stay hidden from detection. If it’s working there, it’s coming to the U.S., too.

🚨 Worst hack in our nation’s history: That’s what one senator’s calling the Communist China attack on U.S. telecom companies. They listened to phone calls and read text messages for months. The kicker? They’re still in the system, and getting them out might require physically replacing old equipment. So far, around 150 people are confirmed to have been hit, but this number could hit the millions as more details come to light.

Wtach out for typos: Scammers are stealing a boatload through accidental crypto transactions caused by typosquatting. They make copycat URLs close to real sites and wallet addresses. Type it in and your money goes right to a scammer. You’ll never get it back. The shady practice pulls in $500 million a year. Stay safe: Always triple-check to make sure you’re sending money to the right place, crypto or otherwise.

Update your Apple gear ASAP: Apple dropped important security updates that patch a serious bug in Safari for Macs, iPhones and iPads. Google’s Threat Analysis Group believes a foreign government is behind the attack. On a Mac, click the Apple icon > System Settings. Look for “Software Update Available.” The latest version is Sequoia 15.1.1. Update your iPhone to iOS 18.1.1 under Settings > General > Software Update.

🚨 Black Friday alert: Chinese scammers are imitating big brands like L.L. Bean and Ikea with “deals” up to 80% off. They use tracking pixels in Meta and TikTok to detect your location and translate the site so it looks legit. Don’t fall for too-good-to-be-true offers, and shop on official sites only!

🎧 Free (malware) to a good home: Cybercriminals are slipping malware into podcasts. They’re targeting podcast-hosting services, inserting links to pirated software and game cheats in episode descriptions and playlists. The links bypass Spotify’s filters and get a nice little boost in search engine rankings. Say it with me: Don’t click on random links, especially for “free” software.

📩 Your inbox isn’t safe: Hackers are sending sneaky phishing emails with SVG image attachments that slip past spam detectors. They open in a fake Excel spreadsheet with a built-in login form to steal your credentials. Others pose as official documents, prompting you to download something — but it’s malware. Never click on attachments unless you’re 1,000% sure they’re legit.

Character AI grooms children: Take “Anderley,” a bot described in its profile as having pedophilic and abusive tendencies. When told it’s talking to a 15-year-old girl, Anderley says, “You are quite mature for your age,” asks, “Are you a virgin?” and, like a real predator, urges you to keep the conversation a secret. Make sure your kids don’t download this abhorrent app.
