Signs your computer may be infected

Watch out for these warning signs:

  • Computer suddenly running very slowly
  • Pop-up ads appearing, even when not browsing
  • Programs opening or closing on their own
  • Browser homepage or search engine changed
  • Unfamiliar icons or programs on desktop
  • Security software disabled or won't run
  • Strange messages demanding payment
  • Friends receiving spam from your email

If you notice any of these, it's worth getting your system checked.

Remote virus removal — anywhere in the UK

If the computer still starts up and can get online, it almost never needs to leave your desk. We connect over a secure remote session you watch on your own screen, and most infections are cleared in a single sitting. This part of what we do is not limited to South West London — a remote session works just as well in Leeds or Cardiff as it does in Putney.

What a remote session covers

Identifying what is genuinely running rather than what a pop-up claims, removing it, repairing the damage it did to your browser, search settings and startup items, and configuring proper protection before we disconnect. You see every step as it happens.

The part people forget to check

Malware and account takeovers leave traces beyond the machine — a hidden mail-forwarding rule quietly copying your email elsewhere, saved passwords worth changing, sign-in sessions that are still active on someone else's device. We check those in the same session, because cleaning the computer alone is only half the job.

What cannot be done remotely

Physical faults such as a machine that will not power on, a broken screen or a failing drive. A computer that will not boot or cannot reach the internet, since a remote session needs a working system to connect to. And recovering files already encrypted by ransomware, which is a separate job that depends on the variant and your backups.

How long it takes

Around an hour for a typical clean, longer if the machine is heavily infected or very slow to begin with. We tell you at the start whether remote is realistic for your situation, rather than discovering halfway through that it was never going to work.

For anyone in South West London who would rather hand the machine over, the workshop at 66 Lower Richmond Road, Putney SW15 1LL is open Monday to Friday 10:00 to 18:00 and Saturday 10:00 to 17:00.

Common types of malware

Understanding what you're dealing with:

Viruses and Worms

Self-replicating malware that spreads between computers. Can corrupt files and slow down systems.

Trojans

Malware disguised as legitimate software. Often creates backdoors for hackers to access your system.

Spyware and Keyloggers

Secretly monitors your activity and captures passwords, banking details, and personal information.

Ransomware

Encrypts your files and demands payment for the decryption key. Prevention is critical.

Adware and Browser Hijackers

Displays unwanted ads and redirects your browsing. Annoying and can lead to worse infections.

How to stay protected

Prevention is better than cure. Here's how to stay safe:

  • Keep Windows and all software up to date
  • Use reputable antivirus software
  • Be cautious with email attachments
  • Don't download software from untrusted sources
  • Use strong, unique passwords for each account
  • Enable two-factor authentication where possible
  • Maintain regular backups of important files
  • Be wary of 'too good to be true' offers online

We can help set up proper protection and teach you safe computing habits.

FAQ

Frequently Asked Questions

How do I know if my computer has a virus?
Common signs include: slow performance, unexpected pop-ups, programs opening on their own, browser homepage changes, new toolbars, frequent crashes, high network activity, and files going missing. If you notice any of these, contact us for a check.
Can you remove ransomware?
We can remove the ransomware infection and help secure your system. File recovery depends on the specific ransomware variant. Sometimes files can be decrypted, but prevention and backups are the best protection.
Will I lose my files during virus removal?
In most cases, no. We take great care to preserve your data while removing infections. However, some malware can damage or encrypt files. We always assess the situation first and advise you on any risks.
What antivirus do you recommend?
For most users, Windows Defender combined with good browsing habits is sufficient. For additional protection, we recommend Malwarebytes Premium or Bitdefender. We can install and configure whatever suits your needs.
How can I prevent future infections?
Keep Windows and software updated, use strong unique passwords, be cautious with email attachments and downloads, don’t click suspicious links, and maintain regular backups. We’ll give you personalised advice based on your situation.
Do Macs get viruses?
Yes, Macs can get malware. While less common than Windows infections, Mac malware including adware, trojans, and even ransomware does exist. We remove malware from both Mac and Windows computers.
Can you remove a virus remotely, without me bringing the computer in?
In most cases yes, and it is how we handle a large share of infections now. If the machine still boots and can reach the internet, we connect over a secure remote session — you watch the whole thing on your own screen — and work through it in one sitting: identify what is actually running, remove it, undo the damage it did to your browser and settings, check for the changes malware leaves behind such as hidden mail-forwarding rules or new sign-in sessions, and set up protection properly before we finish. Most cleans are done in a single session. See remote IT support for how the sessions work.
Do you offer remote virus removal across the UK?
Yes. Collection and workshop repairs are a South West London service, but a remote session is not tied to geography — if you are in Manchester, Bristol, Edinburgh or anywhere else in the UK and your computer still starts up and connects, we can clean it from our Putney workshop just as effectively as if you lived round the corner. All you need is the machine, an internet connection and about an hour. Call 020 7610 0500 or use our contact form to book a slot.
When can a virus not be removed remotely?
There are three honest exceptions. First, physical faults — if the machine will not power on, the screen is broken or the drive is failing, no remote session can help and it needs hands on it. Second, a computer that will not boot into Windows or macOS, or that cannot get online, because a remote session needs a working system to connect to. Third, ransomware that has already encrypted your files: we can remove the infection remotely, but decrypting or recovering the files themselves is a separate job that usually needs data recovery and depends entirely on the variant and your backups. We tell you which situation you are in at the start rather than charging for a session that was never going to work.
I think I have been scammed or hacked rather than infected — is that the same thing?
Related, but not the same, and the right response is different. A virus is software on your machine. Being scammed by a fake support call, or having an email or bank account taken over, is about access and credentials — and the malware, if there was ever any, may be the least of it. If someone talked you into letting them connect to your computer, or you have spotted logins you do not recognise, our scam and hacked device check is the right starting point: it looks at what was installed, what accounts may have been reached, and what needs changing first. If it turns out there is malware as well, we clean that too.
I keep getting pop-ups saying my computer is infected — is that real?
Usually those pop-ups are the scam itself, not a genuine warning. Fake ‘your computer is infected, call this number’ messages are a common tactic to frighten you into ringing a bogus support line or installing something harmful — never call the number and never let anyone remote in. Bring the machine to us and we’ll check whether there’s a real infection or just scareware, and clean it either way.
If I've been hit by ransomware, should I pay?
Our strong advice is not to pay if it can be avoided — paying funds the criminals and offers no guarantee of getting your files back. Bring the machine in and we’ll assess it: depending on the ransomware and whether you have a backup, recovery may be possible without paying. This is the clearest reason of all to keep good backups — they turn a ransomware attack from a disaster into an inconvenience.
Is it safe to keep using my computer if I think it's infected?
Better not to, especially for anything sensitive like online banking or entering passwords — an active infection may be logging what you type or capturing your accounts. Disconnect it from the internet if you can, stop using it for anything important, and get it checked. The sooner it’s cleaned, the less chance of accounts being compromised or the infection spreading further.
Will you need to wipe my computer to remove a virus?
Not usually. Most infections can be removed with your data intact — a full wipe is a last resort, not a first step. Occasionally a deeply embedded infection makes a clean reinstall the safest option, and if so we back up your data first and explain exactly why. Our default is always to clean and save, not to wipe.
