How to keep it out
What we do
How we remove it
Bring it to our workshop in Datchet, near Windsor and Slough, and we’ll tell you what we found in plain English.
- We scan it with up-to-date tools, for viruses, malware, adware and remote access programs that let someone else control your computer.
- We remove what we find, then scan again to make sure it’s gone.
- We check the places malware hides: browser extensions, your home page and search settings, and the programs that start with your computer.
- We install the updates for your operating system and browser that close the gaps malware gets in through.
- We show you how it probably got in and what to change.
Your files stay where they are. If an infection has gone too deep to clean safely, we’ll talk to you about them first.

Scams, security and keeping it out
Scams and fake support callsCallers who say they’re from Microsoft, Apple or your bank
Some of the worst problems start with a phone call or a pop-up rather than a virus. A caller says they’re from Microsoft, Apple, your broadband company or your bank, and tells you your computer has a problem.
They ask you to install a program so they can fix it. Once they’re in, they can see your screen, copy your files and ask for payment.
Microsoft and Apple don’t ring people out of the blue about viruses, and a genuine warning never asks you to call a number.
If you get a call like this, hang up. If a pop-up warning won’t close, hold down the power button to turn the computer off.
If you’ve already let someone on:
- Disconnect from the internet and turn the computer off.
- Call your bank if you gave them card or bank details, or logged in to online banking while they were connected.
- Change your passwords from another device, starting with your email, because that’s how other passwords get reset.
- Bring the computer in. We remove the remote access programs they installed and check for anything else they left behind.
Windows PCsMicrosoft Defender, Windows 10 updates and fake antivirus
Windows 10 and Windows 11 come with Microsoft Defender antivirus built in, as part of Windows Security. Keep it switched on and keep Windows updated.
Some malware turns it off, so if Windows Security says it’s off and won’t turn back on, get the computer checked.
Windows 10 support ended on 14 October 2025. A Windows 10 PC only gets security updates now if it’s signed up to Microsoft’s Extended Security Updates, which run until 12 October 2027.
Be wary of “free” antivirus pop-ups and programs that claim to have found hundreds of problems: many of them are the malware.
MacsAdware, fake cleaner apps and browser extensions
Macs get malware too: adware, fake “cleaner” apps and browser extensions that change your search engine and fill pages with adverts. They usually arrive with a free download or a fake update prompt on a website.
macOS has protection built in, but it can’t catch everything. We remove malware from Macs too, for the same price.
If your Mac is slow but clean, a MacBook service may be what it needs instead.
Keeping it outUpdates, safe downloads, passwords and backups
- Install updates when your computer asks, for the operating system and your browser.
- Only download programs from the maker’s own website or the app store, never from a pop-up.
- Use a different password for each account, and a password manager to remember them.
- Turn on two-step verification for your email and banking.
- Back up your files, so a virus or a failed drive can’t take them with it.

Common questions
Your questions answered
How much does virus removal cost?
Virus and malware removal costs from £69.99, including VAT, for Windows PCs and Macs. We look at your computer first and confirm the price before we start.
Do Macs get viruses?
Yes, though less often than Windows PCs. On a Mac it’s usually adware, fake apps and unwanted browser extensions, often installed alongside a free download. macOS has protection built in, but it doesn’t catch everything.
I let a fake support caller onto my computer. What should I do?
Disconnect from the internet and turn the computer off. If you gave them card or bank details, call your bank straight away. Change your important passwords from a different device, starting with your email, then bring the computer in so we can remove what they left behind.
Will I lose my files?
Not normally. We remove the infection and leave your files where they are. If it has gone too deep to clean safely, we’ll talk to you about your files and a fresh install before we do anything else.
How long does virus removal take?
Same day where possible. A badly infected computer can take longer, and we’ll tell you when to expect it back.
Is there a warranty on virus removal?
No. We clean your computer as it is on the day, but that can’t stop something new getting in later. That’s why we finish by showing you how it got in and how to keep it out.
