1- Keep your software up to date, especially your security software.
Most updates are done automatically by Windows, but if a window opens to inform you of an update of a program or your antivirus, accept it.
2- Make a copy of your files.
If a virus were to enter your computer, it could destroy your files, which would then be lost. Make sure you don’t lose your documents, photos, videos, music files by making a backup copy. The ideal solution is to purchase an external hard drive (less than $100). Simply plug it into the computer (on the USB plug) and copy your documents. Perform this operation regularly; it is even possible to have an automatic backup. So, if your computer’s hard drive is damaged, your files will be intact on your external drive. You can also save files to a USB stick, but it contains fewer files.
3- Limit access to your wireless network.
When installing your router, it is suggested that you enter a WAP decryption key: this password will prevent people who are in the vicinity from using your Internet connection. This WAP is essential.
4- Be careful before giving out your personal information on the Internet.
Create a Webmail address (Gmail, Hotmail, Yahoo) that you can use to register for blogs, contests or to become a member of certain sites. When creating this address, use a fictitious identity (note the names and numbers chosen). This way, any spyware will not have access to your contact details and personal information. Never disclose banking, financial, credit card numbers or passwords by email, even to a friend. When you need to complete a form on a website, make sure it is a reliable site.
5- Be careful before opening an attached file or activating a hyperlink.
Receiving an email from a stranger containing an attached document or hyperlink? Do not open either one. In principle, you should not open the email of a person you do not know or of an organization or business where you have not registered yourself.
6- Make your transactions on reliable and secure sites.
Check the URL address. By clicking on the Buy or Pay option, this address must start with https. For your purchases, prefer sites where you are offered to pay with a secure system such as PayPal.
7- Keep proof of your transactions and check your statements.
Paying bills, managing your bank accounts or making purchases online is very convenient. However, take the time to save all statements and invoices in a file and print a copy. This will allow you to make claims, if any, and ensure that everything is in compliance.
8- Create passwords that are difficult to guess.
Your last name, first name, date of birth are not secure passwords. Only you should be able to know your password.
9- Disconnect from networks when you end a session and close your computer after use.
On Facebook, on your bank’s website, on Skype and other places where you need to log in to browse or participate, click on Log Out or Log Out before closing the site.
