Computer Data Security

Remote Registry Editing

Only you should be editing your Windows registry, so make sure this service is disabled by clicking Start, Run, and then typing "services।msc." Scroll down to Remote Registry and make sure the service is stopped, and then set it to either manual or disable.

Lock It

It's always a good idea to lock your PC if strangers are nearby and you step away for a few minutes। Just press Windows key+L to lock your PC. Alternatively, you can set your screensaver (via the Screensaver tab in Display Settings under Control Panel) to require a password if it's deactivated by checking the box in "Settings" that says "On resume, password protect."

Softwares Up to Date

Hackers and crackers love to take advantage of exploits found in software, which causes the developers to release a patch to plug up the holes। Therefore, it's imperative you not only enable Windows Update but also download the latest version of any software on your system, especially your Web browser and antivirus program.

Files

Virus makers love peer-to-peer file-sharing services। They name their virus "Angelina Jolie Wallpapers" or something similar and upload it. Then millions of people download it, launch it, and wonder why their computers are infested with viruses. Download with caution, and always use antivirus software.

Verify Your Backups

Many people have a "set it and forget it" mindset when it comes to backups। Even after you establish a regimen, however, it's critical that you check the target folders periodically to ensure the proper files are being backed up. If not, re-configure your backup routine to make sure it's working properly.

Extension Viewing

By default, Windows hides file extensions, and virus-makers exploit this feature by giving their executable program names like Popularsong.exe, which appears as a harmless audio file if you have extensions hidden. To enable extension viewing, open any folder and click Tools, Folder Options, and uncheck "Hide extensions for known file types."
