A computer hacker is someone who develops, changes or attempts to circumvent computer security hardware or software. This can either happen for negative (criminal) or positive reasons. Criminal hackers develop computer malware or spyware to gain access to confidential information.
If you believe someone you don't know has accessed information from your computer, check for these signs:
- Your inbox contains mailing errors or mailer-daemon messages for email you didn't send.
- People you know are getting emails from you that you didn't send.
- There are outgoing messages in your Sent, Drafts or Outbox folder that you didn't create or send.
- Your account folders (Sent, Deleted, Spam, Inbox, etc.) have been emptied or deleted.
- Your Address Book contacts have been erased.
- During sign-in or when sending a message, you're asked to pass an image challenge.
- Emails you try to send are suddenly getting refused and returned to you.
- There are contacts in your Address Book you didn't add.
- You keep getting bumped offline when you're signed into your account.
- Your email signature suddenly has a link you didn't put there.
- You're not getting new mail.
- Create a strong password. For the most up-to-date recommendations for making a strong password, Note that passwords should be at least six characters long and include at least one number, letter (combination of upper and lower cases) and special character ($, *, &, !, etc.). Make sure your new password is different from any other passwords you have used. Also, if you use the same password for other online accounts such as social media and financial services, change those passwords as well. It is strongly advised that you use different passwords for different social media accounts.
- Make sure you have antivirus software installed and updated. Virus scans search for any spyware, viruses or other malware that may have found their way onto your computer. Run scans frequently to make sure your computer is free of all malware.
- Don't download attachments (e.g., pictures, games, electronic greetings) unless it's from someone you know.
- Anti-virus software searches for evidence of the presence of viral programs, worm, bombs, and Trojan horses by checking for the characteristic appearances or behaviors that is typical of these programs. When found the program logs its discovery, its type, often its name or an identifier, and it potential for damage. The anti-virus software then eliminates or isolates/quarantines the infected files. For the individual, commercial software is relatively inexpensive; however, there are free anti-virus programs available.
- Since new viruses appear almost daily with new code it is imperative that you update you antivirus program often to keep up with these threats; therefore, make sure to set your program to update automatically. To avoid the annoyance of computer slowdown schedule full scale scans late at night.
- The same is true for your Windows Operating System. Very often, your OS is where hackers discover the holes to exploit. Of course, in an ever-continuing battle, this software is continuously updated with security patches.
- Finally, secure your wireless network with a router that has a built in firewall. Almost all wireless routers are set to no security when first installed. Log into the router and at least set it to basic security with a strong password to replace the factory setting that any hacker knows. A firewall or router that is not configured properly or non-existent allows hackers to scan passwords, e-mails, or files that cross your network connection.
