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.

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 Start by checking for too many open tabs or outdated software.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.
