Update the Windows
With every update, Microsoft patches the security loopholes in Windows. Therefore, install a genuine OS update to protect the PC from hackers.
Try avoiding third-party software or freeware
You must be cautious while downloading any third-party software or freeware. Try, as far as possible, to avoid them because many times they come with hidden malicious programs.
Avoid clicking on pop-up ads
Remember there is nothing like free rewards. The pop-up ads claiming to give you free rewards such as a new iPhone are mostly fake. Therefore, don’t click on such pop-ups and close the site immediately.
Do not open unknown emails
Most of the new computer viruses enter the device through email attachments. Therefore, to stay protected, do not open any suspicious email from an unknown source.
Use hard to guess passwords
The password is key to your sensitive data. If you use a weak password, then the hackers can easily break open the lock and steal your information. Therefore, always use passwords that are tough to guess and unique.
Backup the files regularly
If data loss is your topmost concern, then create regular file backups. Using an external cloud drive to backup the crucial files helps prevent data loss.
Turn on the Microsoft Defender Firewall
The firewall prevents hackers and suspicious programs from accessing your system. Therefore, activate the Microsoft Defender Firewall.
Avoid using open wifi
Resist the temptation to access free internet via open wifi. The non-password protected and unencrypted wifi can be a trap laid by hackers. Don’t fall prey to it.
Make your network secure
An unsecured wifi invites hackers to invade your PC. They can easily connect to it and access your data. Therefore, always secure your network with WPA or WPA2 encryption.
