8 Signs Your Computer Has a Virus (and What to Do About It)

Modern malware doesn't announce itself with skulls and flashing screens — it hides, steals and quietly makes money off your computer. At Real IT Consulting we clean infected machines every week for customers around Nerang, Ashmore, Parkwood and across the Gold Coast. Here are the signs that actually matter, and what to do if you spot them.

The warning signs

1. Pop-ups outside your browser. Ads and "security warnings" appearing on the desktop itself are a classic adware infection.
2. Your browser has new management. Homepage changed, searches redirected through odd sites, toolbars you never installed — a browser hijacker is earning money from your clicks.
3. Fake security alerts demanding calls or payment. A full-screen warning with a phone number claiming to be Microsoft is 100% scam, every time. Microsoft does not lock your screen and ask you to ring.
4. The computer works hard doing nothing. Fan roaring while idle can mean hidden software — sometimes crypto-mining malware — using your hardware and power bill.
5. Friends receive strange messages from you. Emails or Facebook messages you never sent mean an account or machine is compromised.
6. New programs you didn't install. "PC optimisers," "driver updaters" and mystery toolbars usually arrive bundled with malware.
7. Antivirus mysteriously disabled. Malware often switches protection off first. If yours won't turn on, take it seriously.
8. Files renamed or unopenable, plus a ransom note. That's ransomware — disconnect from the internet and networks immediately and get professional help before doing anything else.

What to do if you're infected

• Stop using the machine for banking and shopping until it's cleaned — infostealers watch for exactly that.
• Don't pay anyone who calls. If "support" rings about your virus, hang up — that's a second scam.
• Change key passwords from a different, clean device — email first, then banking — and enable multi-factor authentication.
• Get it professionally cleaned. Free "quick scans" often miss persistence mechanisms that reinstall the malware after reboot.

What professional removal involves

At Real IT Consulting we don't just run a scan and hand it back: we remove infections and their reinstall mechanisms, check browser extensions and scheduled tasks, verify your security software is genuine and working, update the system to close the hole that let it in, and check what may have been exposed — then set you up so it doesn't happen again. If the infection has trashed Windows, we can reinstall cleanly with your files preserved.

Prevention, briefly

Updates installed promptly, one reputable antivirus (not three), scepticism toward email attachments and "free" software downloads, an ad-blocker, and backups — because ransomware's only true antidote is a backup it can't reach.

Real IT Consulting removes viruses and malware for homes and businesses across Nerang, Ashmore, Parkwood, Southport, Robina, Helensvale and the entire Gold Coast, plus Brisbane — remotely in many cases, same day where possible.
