PC & Laptop Virus Removal Service London
Is your computer running slow, showing endless pop-ups, or acting strangely on its own? These are classic signs of a virus, malware, spyware, or ransomware infection. At PC Fix London, our technicians provide a thorough virus and malware removal service for PCs, laptops, and Macs — not just a quick antivirus scan, but a full clean-up that finds and removes the root infection while protecting your files.
Whether it’s a browser hijacker, spyware tracking your activity, or something more serious like ransomware, we diagnose the problem, remove it safely, and help secure your device against future infections.
Common Signs Your Computer Has a Virus
If you’re noticing any of these symptoms, it’s worth getting your device checked before the problem gets worse or spreads to other files:
Sudden Slowdown
Your device responds slowly and programs take much longer to open than usual.
Constant Pop-Ups & Ads
Unwanted advertisements or pop-up windows appear even when you’re not browsing.
Frequent Crashes
Your PC crashes, freezes, or shows a “Not Responding” message more often than normal.
Homepage or Settings Changed
Your browser homepage, search engine, or settings change without you doing it yourself.
Antivirus Disabled Itself
Your security software switches off on its own, or you can no longer open it.
Unusual Internet Activity
Your internet connection is unusually busy, or your data usage spikes for no clear reason.
Unfamiliar Programs or Toolbars
New icons, toolbars, or apps appear on your device that you never installed.
Files Missing, Locked, or Renamed
Files disappear, become inaccessible, or are renamed with strange extensions — a possible sign of ransomware.
Strange Messages or Warnings
Unexpected security warnings, ransom notes, or system messages you don’t recognise appear on screen.
How Viruses and Malware Get Onto Your Device
Infections usually arrive through everyday activity rather than anything obviously suspicious:
Email Attachments & Phishing Links
Opening an infected attachment or clicking a link in a fake or spoofed email.
Downloaded Files & Software
Free downloads, cracked software, or files from untrusted websites bundled with hidden malware.
Infected USB Drives
Plugging in an infected USB stick or external drive from another device.
Compromised Websites
Visiting a hacked or malicious website that silently installs malware in the background.
Outdated Software
Old, unpatched operating systems or applications with known security vulnerabilities.
Fake Software Updates
Pop-ups disguised as urgent “update your software” prompts that install malware instead.
What to Do If You Think You’re Infected
If you notice any of the symptoms above, especially locked or renamed files, act quickly to limit the damage:
- Disconnect the device from the internet and any home network to stop the infection spreading or communicating out.
- Avoid entering passwords, online banking details, or other sensitive information on the infected device.
- Don’t try to “fix” a suspected ransomware infection by paying a ransom or running random downloaded tools — this can make recovery harder.
- Bring the device to us as soon as possible — the sooner we look at it, the better the chances of a full clean-up and file recovery.
Your Data Stays Our Priority
A common worry when bringing in an infected device is losing photos, documents, or work files. Our approach is built around protecting your data wherever possible: we use targeted removal methods rather than defaulting to a full wipe, and we back up accessible files before starting deeper cleaning work where appropriate.
If a virus or ransomware has already corrupted, hidden, encrypted, or deleted your files, our in-house data recovery service can attempt to retrieve them as part of the same visit — so you don’t need to go to a separate company for that step.

Frequently Asked Questions
Q: How do I know if my computer has a virus?
A: Common signs include a sudden slowdown, unexpected pop-ups or ads, frequent crashes, your homepage or browser settings changing on their own, new toolbars you didn’t install, your antivirus being disabled without your input, and unusually high internet or CPU activity.
Q: Will I lose my files or data during virus removal?
A: In most cases no — our virus removal process is designed to clean the infection without wiping your files. If the malware has already corrupted or encrypted data, we will discuss data recovery options with you before proceeding with any further work.
Q: Can you remove ransomware?
A: We can remove many ransomware infections and secure the system to prevent further damage. Whether encrypted files can be recovered depends on the specific ransomware variant, and we’ll be upfront with you about the realistic chances before starting any recovery attempt.
Q: Do you need to reinstall Windows to remove a virus?
A: Not always. We start with targeted removal tools to clean the infection while preserving your files and installed programs. A full operating system reinstall is only recommended in severe cases where the system has been deeply compromised or a clean install is the safer option.
Q: How long does virus removal take?
A: Most virus and malware removals are completed the same day. More severe or deeply embedded infections, or cases requiring a full reinstall, may take 1-2 days.
Q: How much does virus removal cost?
A: Cost depends on the severity of the infection and whether data recovery or a system reinstall is needed. We provide a free diagnosis and a fixed quote before any work begins.
Q: Do you install antivirus protection afterwards?
A: Yes, we can install and configure reputable antivirus and anti-malware protection after the clean-up, along with advice on safe browsing habits to help prevent reinfection.
Q: Can you recover files damaged or deleted by a virus?
A: Yes. If a virus has corrupted, hidden, or deleted your files, our data recovery team can attempt to retrieve them as part of the same visit, working alongside the virus removal process.
Q: Do you remove malware from Mac computers too?
A: Yes, we remove viruses, malware and adware from both Windows PCs and Mac computers.
Q: Do I need an appointment for virus removal?
A: No appointment is needed. You can walk into our Central London workshop during opening hours, or arrange courier collection or a home visit.
