Viruses and malware aren't always obvious. Sometimes your computer just feels "off". Here are five tell‑tale signs that you might be infected — and what to do about it.
1. Sudden slowdowns
If your once‑snappy PC now takes minutes to open a browser, malware could be hogging resources in the background. Check Task Manager for unfamiliar processes eating CPU or memory.
2. Pop‑ups everywhere
Fake antivirus warnings, "You've won a prize!" ads, or browser tabs opening by themselves are classic signs of adware or worse. Never click on them — they often install more malware.
3. Missing or encrypted files
Ransomware renames or locks your files and demands payment. If documents suddenly have strange extensions or won't open, disconnect from the internet immediately and seek professional help.
4. Friends receive strange emails from you
If your contacts report spam or phishing emails sent from your address, your email account or device may be compromised. Change passwords immediately from a clean device.
5. Unusual network activity
Your router lights blinking furiously when you're not using the internet? Malware could be using your connection to attack others or send spam.
If you spot any of these signs, don't wait. Contact Computer Technical Solutions for a professional virus removal and security check.
