A computer virus is a type of harmful software that can damage your computer, phone, or tablet. It can slow your device down, show unwanted adverts, or try to steal personal information such as passwords or banking details.
You can accidentally get a virus in several ways, such as clicking unsafe adverts, downloading apps from unofficial sources, or opening suspicious email or message attachments.
“Virus” is a specific type of malware. Malware is the general term for any software designed to cause harm or disruption. Some viruses can also copy themselves and spread to other devices without you knowing.
How do you know if you might have a virus?
Common signs include:
- Constant pop-up adverts
- Strange warning messages
- Your device running much slower than usual
- Apps or settings changing on their own
What should you do if you think you have one?
If you suspect your device is infected, run trusted antivirus software such as ESET and follow the guidance it provides. In more serious cases, professional IT support may be needed to fully remove the issue. We can help with this. Contact Giraffe Connected Solutions Limited.
How can you protect yourself?
The best protection is keeping your devices and software up to date, as updates fix security weaknesses that viruses try to exploit. It also helps to:
- Avoid opening links or attachments from unknown senders
- Only download apps from official app stores
- Be cautious with unexpected emails, texts, or messages
Staying updated and being careful online greatly reduces your risk of infection.
