Does your PC have a virus? | Jupiter IT Support Hull, Grimsby, Leeds


What To Do If You Think Your PC Has A Virus.


If there’s a chance your PC has a virus, the number one thing you shouldn’t do is ignore it. For one, the slow performance will raise your blood pressure and for two, continued use of an infected device can leave you vulnerable to cyber attacks with a heavy cost.

What are the signs your PC has a virus?

You don’t have to be an IT specialist to suspect a virus on your PC or laptop; there are a number of common signs you can look out for:

Frustratingly slow

If your computer begins to run significantly slower (we’re talking, time to make a coffee while Outlook loads), there’s a good chance that there’s a programme running in the background that probably shouldn’t be there.

Annoying pop-ups

They could pop up on your homepage or while using your browser, either way, by design, you can’t miss them! It’s good first to check if they are related to any chosen Chrome extension but if not, a virus is likely to be at the root of the problem.


If you notice your fan firing up when you access your hard drive or storage, a virus should be your first suspicion.

Unfamiliar programmes

Never ignore a new icon: These can show up in your systems tray and be easily dismissed but the chances are it’s a malicious programme that shouldn’t be there and requires action.

Change in behaviour

All computers develop their own tics with age, but any ‘overnight’ changes in the behaviour of your hardware should be looked into to be on the safe side.

You could be experiencing some of these issues without any malicious root cause; in this case, take a look at these quick-fixes in this blog:

10 Common IT Problems and How To Solve Them.

Steps to take if you think you PC has a virus.

If all this is sounding familiar, it’s important you take action sooner rather than later. Letting a virus fester leaves you open to a cyber attack that could cost you money, data, or both.

Step 1: ensure you have adequate anti-virus software

Free Anti Virus solutions may be adequate for your home PC, but business systems should have a good market-leading product that is automatically updated regularly.  

Step 2: update and disconnect

Firstly, check your machine is running the most up-to-date version of your software – every update includes the odd security boost so make sure you keep on top of these.

When you know your system is up-to-date, you need to disconnect from the internet – you can do this via your PC or simply unplug your router for certainty.

Step 3: safe mode

Now it’s time to re-start your PC in safe mode: Go to settings > Update and security > Recovery. From here, select Restart now.

Step 4: time to scan

When your PC has rebooted, it’s time to run your virus scanner. Right-clicking on the AV icon in your system tray will give you an option to perform a “Deep Scan”. This will hunt down the cause of any suspicious behaviour. 

Step 5: start a fresh

Finally, when the scan is complete and any necessary action has been taken, you need to restart your machine. It’s helpful to evaluate the process you’ve been through by doing a few daily tasks that have been causing issues. With any luck, you’ve nailed it!

Step 6: alert others

Never assume that because the virus is gone, all is forgotten. It’s good practice to alert colleagues to your experience in case of any spread; it’s also wise to let your IT service provider know for reference.
