All the above reasons make computer virus prevention very important for computer users.
Common Ways Computer Viruses Spread
To begin, it is important to understand the common methods through which computer viruses are spread, and this will be the best way to prevent them from infecting our computers.
1. Infected Email Attachments
Hackers send emails that carry attachments, and if you open the attachments, you are immediately infected by the virus.

Official websites
Trusted app stores
Verified vendors
And avoid downloading:

Since they contain viruses.
4. Be Careful with Email Attachments
Emails are often used by hackers to distribute viruses.

Do not open any attachment from an unknown sender
Be cautious of suspicious emails
Do not click on any unknown link
Even if the email is from a trusted source, there is a high probability of a virus being embedded in the attachment.
5. Use a Firewall
Firewall acts as a protective layer between the computer and the internet.
Therefore, a firewall helps to:
Block unauthorized access
Monitor network activity
Block malicious connections
Firewall protection comes pre-installed on the computer but should be enabled.

Having your data backed up will allow you to retrieve your data in the event your computer gets a virus.
You can store your backups in the following places:
External Hard Drives
Cloud Storage
Network Storage
You should store your backups in a safe location.
8. Use Strong Passwords
Weak passwords allow hackers to gain access to your computer and spread viruses.
You should use passwords that have the following characteristics:

Lowercase Letters
Numbers
Special Characters
You should not use weak passwords such as 123456 or the word “password.”
9. Avoid Suspicious Pop-ups
Some websites display fake pop-up messages that tell you your computer is infected.
These are attempts by hackers to trick you into installing a virus.
You should never click on these suspicious pop-ups.
You should instead:
