A strong password is a good protection for online transactions. The password should be strong & complex to keep our online accounts protected from unauthorized accesses. For a strong password, use combinations of special symbols, numbers and special characters. The password should be at least 8 characters long.

While setting a password, try to avoid common words and repeated characters or numbers like abcdef, 123456, 22222 etc. Such passwords are easier to hack. So, avoid such passwords.

Firewalls can be used to block access to particular websites or to prevent certain users or machines from accessing certain servers or services.

If you select trusted sites, you can add the required or commonly used websites to the list of trusted sites. In this way, sites are filtered and pop up ads, harmful JavaScript or spyware are less likely to damage your PC.
