Do not tick on attachments to emails from people you do not know, and do not tick on links in emails that ask you to verify log-in information. Only do online transactions with safe websites. Decide which websites are safe since safe websites begin with https as opposed to standard http. Prevent clicking on free-offer banners on websites, and close Internet browser when you are not using it.

Do hard-drive maintenance at least once a month, containing defragmenting and disc-scanning functions. Do a removable media backup of personal data and main files at least once a week.
