What is Malware?
How it works
Malware can infect a computer from USBs, automatic downloads via email or websites and third-party apps requiring access to social media. The software can remain undetected for some time and cause problems with your computer or files.
Common signs that malware has infected your system can be a slow computer, seeing lots of pop ups and ads, programs behaving strangely and friends reporting receiving spam from you.
For example, when you open up your web browser you might see lots of advertisements asking you to click on them, some of which may even move or flash. If you see this, it’s best to run an anti-virus scan. This could be a sign that you need to remove some malware from your computer.
