A slow, glitchy computer covered in pop-ups is more than an inconvenience — it can mean your files, passwords and personal details are at risk. Microsys provides virus and malware removal for Perth homes and businesses, working through Perth CBD and the surrounding suburbs to get infected computers cleaned up properly, not just patched over.

Every job starts with a real diagnosis. Rather than running one scan and calling it done, our technicians work out what's actually on your system and what it's changed, before removing it and checking your computer is genuinely clear.

If your computer's issues turn out to be broader than an infection — say, it's also running slow due to an ageing hard drive — our Computer Repairs Perth team can look at the hardware side at the same time.

Warning signs

Signs You May Have a Virus

Not every computer problem is a virus, but these are the symptoms Perth customers most often ask us about. If a few of these sound familiar, it's worth getting your computer looked at.

Unexpected pop-ups

Ads or warning windows appearing even when your browser isn't open.

Browser redirects

Searches or new tabs landing on pages you never chose to visit.

Slow computer performance

A sudden, unexplained drop in speed, especially at start-up.

Unknown programs appearing

Software, toolbars or icons you don't remember installing.

Unusual error messages

Crashes, warnings or dialogue boxes that weren't there before.

Antivirus warnings

Alerts from your security software, or it switching itself off.

Homepage or search changes

Your browser's homepage or default search has changed on its own.

Excessive advertising

Far more ads than usual, including on sites that don't normally show them.

Freezing or crashing

Programs, or Windows itself, locking up or restarting unexpectedly.

Suspicious account activity

Logins you don't recognise, or friends receiving messages you didn't send.

These symptoms can have more than one cause — an ageing hard drive or a failed update can look a lot like an infection. A proper diagnosis is the only way to know for certain, which is exactly where we start.

How it works

Our Virus & Malware Removal Process

From your first call to a computer that's clean and better protected — here's how we handle an infected or suspicious computer.

1

Initial assessment

We talk through what you're seeing and take a first look to understand the likely cause.

2

Malware & virus scanning

A full system scan using professional-grade tools to surface hidden threats, not just the obvious ones.

3

Threat identification

Every detection is reviewed and confirmed, separating genuine threats from harmless files.

4

Removal & cleanup

Confirmed threats are removed, along with the leftover files and settings they installed.

5

System & browser checks

We check extensions, startup programs and settings for anything the infection changed.

6

Security updates

Windows, your browser and key apps are brought up to date to close the gaps malware relies on.

7

Final verification

A follow-up scan confirms your computer looks clean before it comes back to you.

8

Prevention recommendations

We explain what let the infection in and what to change, so you're in a stronger position.

After your clean-up

Protecting Your Computer After Cleanup

Removing an infection is only half the job — the other half is making it harder for the next one to take hold. Once your computer's clean, a few habits and the right setup make a real difference to your risk of getting reinfected.

For Perth businesses in particular, this is often worth looking at more broadly. Our Cyber Security Perth service covers protection across a whole team or network, not just one computer, and our Data Backup & Transfer service means that even if something does slip through in future, your files aren't the thing at risk.

Microsys technician checking a laptop for malware in Perth

Keep Windows & apps updated

Security patches close the exact gaps a lot of malware relies on.

Use reputable security software

A properly configured antivirus catches most threats before they take hold.

Tighten browser security

Remove extensions you don't recognise and keep your browser itself updated.

Use strong, unique passwords

A password manager makes this realistic across every account you have.

Turn on multi-factor authentication

An extra step at login that stops most stolen passwords from being useful.

Practise safe email habits

Treat unexpected attachments and links with caution, even from people you know.

Avoid suspicious downloads

Free software, cracked programs and random pop-up "updates" are common infection sources.

Learn to recognise phishing

Urgent, alarming or too-good-to-be-true messages are a red flag, whatever they claim to be from.

Keep regular backups

A recent backup means an infection is an inconvenience, not a disaster.

Know where your data lives

Photos, documents and financial records should be backed up somewhere a virus can't reach.

Virus & Malware Removal FAQs

Answers to the questions Perth customers ask us most. Still not sure? We're happy to help over the phone.

Common signs include pop-ups, a sudden slowdown, antivirus warnings, a browser that's changed on its own, or programs you don't remember installing. If you're noticing a few of these together, it's worth having your computer checked rather than waiting to see if it gets worse.
Yes. We remove viruses, spyware, adware, browser hijackers and other malware from Windows and Mac computers, for homes and businesses across Perth, then check your system is properly clean before handing it back.
Yes, this is one of the most common symptoms. Malware often runs in the background using up memory and processing power, which is why an infected computer can feel sluggish, freeze, or take far longer to start up than usual.
Some types of malware, such as spyware and keyloggers, are specifically designed to capture passwords, banking details and other personal information. If you suspect this has happened, it's a good idea to change your important passwords once your computer has been cleaned.
We'd generally suggest avoiding online banking, shopping or entering passwords until it's been checked, since some malware is designed to capture exactly that kind of information. Basic use is usually fine, but it's best to get it looked at as soon as you reasonably can.
It depends on how deep the infection goes. Many computers can be assessed and cleaned within a few hours, while more complex or long-standing infections can take longer. We'll give you a realistic timeframe once we've had a look.
In most cases yes — we focus on removing the malware itself rather than your personal files. Where there's any risk to your data, we'll talk you through it and can back up your files first for extra peace of mind.
Keeping your software updated, using reputable security software, being cautious with email links and downloads, and having good backups in place all make a real difference. We're happy to walk you through the specifics for your setup after a clean-up.
