Hackers are professionals (Business provide hacking platforms on the Web)

Prevent Virus and Hacking

  • Create a <user> account for internet browsing
  • Only use the <administrator> account for important things
  • Don’t let the internet store passwords
  • Don’t give anyone access to your computer remotely unless you contact them and know who they are.
  • Get updates from the “official” site
  • Keep systems current by applying the latest security technology updates and antimalware definitions.
  • Enable automatic operating system updates, or download operating system updates regularly, to keep them patched against known vulnerabilities.
  • Configure antimalware software to automatically scan all email and instant-message attachments.
  • Make sure email programs do not automatically open attachments or automatically render graphics, and turn off preview pane.
  • Configure browser security setting to medium level or above.
  • Use great caution when opening attachments, especially when those attachments carry the .jar, .pdf, .doc, or .xls extentions.
  • Never open unsolicited emails or unexpected attachments- even from known people.
  • Beware of spam-based phishing schemes. Don’t click on links in emails or instant messages.
