What a factory reset actually does
A factory reset wipes your Windows installation and reinstalls it fresh. Any malware living inside Windows is gone. But there are important caveats:
- Your files are deleted — anything not backed up is gone
- All programs need to be reinstalled from scratch
- It doesn't fix whatever caused the infection in the first place
- Advanced rootkits can survive by hiding in UEFI/BIOS firmware, below the operating system
- If an infected USB drive or external drive was connected during or after the reset, the machine can be reinfected immediately
What professional virus removal does differently
Professional removal uses specialist tools to identify and eliminate the infection without wiping your data:
- Identification: We find exactly what infected the machine — the strain, how it got in, and what it did
- Complete removal: We use tools that consumer antivirus often misses, including offline scanning (booting from a clean environment to scan the infected drive)
- Entry point secured: We identify how the infection got in — a phishing email, a software vulnerability, a compromised download site — and close it
- Data stays intact: Your files, photos, documents remain exactly where they were
- Verification: We confirm the machine is clean before returning it
When a factory reset is the right call
A full wipe is the better choice when:
- The infection is severe and has deeply compromised the system — some ransomware variants are easier to recover from with a clean install
- There's no important data to preserve (or it's already backed up)
- The machine has been running badly for a long time and a fresh start is genuinely needed
Even then, a professional reset includes data backup beforehand, identifies the entry point, and ensures clean reinstallation — not just clicking "Reset this PC".

| Files preserved | No — wiped | Yes |
| Removes most malware | Yes (usually) | Yes |

The Perth heat factor
Worth knowing for WA residents: malware often thrives in the same environment as overheating — a slow, poorly maintained machine. If your PC has been sluggish and running hot in Midland's summer heat, there's a chance it's both infected and thermally stressed. We check both during a virus removal service.
Think you have a virus? Don't wipe it yet.
Bring it to our Midland WA workshop. We'll remove the infection and return your machine with all your files intact — usually same day.
Frequently asked questions
Does a factory reset remove all viruses?
A full factory reset (wipe and reinstall Windows) removes most malware. However, some advanced threats can persist in the UEFI/BIOS firmware, hide in external drives connected during the reset, or be reintroduced immediately if the original infection source isn't identified. Professional removal also finds and eliminates the entry point so the infection doesn't return.
What is the difference between a factory reset and professional virus removal?
A factory reset wipes Windows and reinstalls it — any malware living in the OS is erased. Professional virus removal identifies exactly what infected your system, removes it without destroying your data, checks for persistence mechanisms, and secures the entry point so it doesn't happen again.
Will I lose my files if I do a factory reset?
Yes — a factory reset wipes your Windows drive. Any files not backed up before the reset are gone. Professional virus removal preserves your files while removing the infection.
How much does professional virus removal cost in Midland WA?
Virus and malware removal at PC Madness typically costs $89–$149. This includes full removal, cleanup, checking for data compromise, and securing the entry point. Most jobs are completed within 24 hours.
