You should only download software from known, secure sources such as the software developer’s website, experts say. Otherwise you face a risk of installing malware on your computer.
You should also never click on an email attachment from an unknown person but rather delete it immediately. Such attachments are a common way for hackers and scammers to launch an attack.
The experts recommend that you install an anti-virus programme on your computer and keep it up to date. It’s also advisable to back up your data regularly to an external drive. – dpa
