Spyware also takes its form in a computer program like a Trojan, appearing to be performing a harmless or even helpful action. However they do not harm your computer, they harm you. Once the program with the spyware has been installed on the system, it runs in the background gathering users personal and confidential data. This means it could be collecting your bank account details, credit card numbers and CVV’s, passwords, e-mails and other important and personal files and documents.
So how does Spyware manage to do all of this? It can scan and read the files on your computer, read your messenger chats and e-mails, track and record your keystrokes (what you type) and collect your internet history. Spyware is also capable of making changes to the settings on your computer, which can result in slow internet speeds, slower boot times and changes to your internet browser such as a different home page or default browser.
