3. Operating system and software updates and patches
No software program can be 100% error-free and safe. Malware and infectious code writers always find one or other way of breaching the defence layer of your computer so they target on the installed programs and the vulnerabilities of your operating system. Compatibility issues or vulnerabilities in software programs may compromise your computer's security and patches/updates are released to eliminate the vulnerabilities in the software programs that you are using.
Often, software patches, updates, and drivers are made available for free so that the corresponding software program and operating systems run properly and stay secure. Though, most of the programs notify you if there is any update available, but if the program that you're using is not able of checking for updates on its own, then you need to verify the program is up-to-date. To check for the updates, you need to visit the official website of developer of the program.

There are multiple online websites which offer online tools to check your machine for potential threats as well as to learn about network vulnerabilities and security.
6. Learn to handle e-mail
E-mail is one of the most popular ways of communication on the Internet, but malware and virus writers are misusing this feature and sending viruses and other infections to get the control of your computer and steal the important information. So you need to be able of identifying if there is any risk attached to the email that you have received. Only your know-how and awareness will keep your personal information and your device safe.
While using e-mail the most common threats that you may encounter are:
Phishing - Phishing or an e-mail phish is a message that you receive from an illegitimate company, but it appears as if your official company like bank have sent it. Such messages and emails ask you to log onto the site to check your account settings or pay the bills or change your account password. However, the e-mails that you receive don’t come from the authorized source. They are just set up to steal confidential information such as your social security information, passwords, credit card information, etc.
Attachments – This is just another and most commonly used way of running the computer users into trouble. If you receive any email attachment from an unfamiliar source, never open or run that e-mail attachment.
