ways a user can keep their home PC secure:
Back up your data – this stores your data somewhere safe so the hacker or virus cannot get to it.
Stay away from rogue websites – websites that seem fake, such as without an unsecured web link and if they have poor layouts
Avoid adverts that sound fake – such as adverts offering “a million dollars” this will probably be a scam to try and steal your personal information
Don’t reveal your personal information to unsafe websites – like if you’re about to buy something from a website that does not seem secure they might steal your card details and such.
Avoid opening unknown emails – these unknown emails may lead to a link that lets a virus into your computer.
