How to Clean Your Computer or Laptop with Windows 10, 8 or ...

The Disk Cleanup utility is perfect for deleting files you never even knew were taking up space, but chances are you have even more old files that can be deleted in order to free up room.

The biggest culprits to look at are photos, videos, and files in your Downloads folder. Over the course of several years, your Downloads folder accumulates photos, documents, and email attachments that you might no longer need and they take up a ton of room on your computers hard drive.

Consider moving some files to a cloud storage platform, like OneDrive, or backing up files onto a separate drive to free up space on your main computers storage. This can significantly improve your computer speed.

Backing up files also protects you in case your hard drive fails, you lose your computer, or if other damages occur.

You can use OneDrive to keep anything you dont need to access often. Its already built into the Windows operating system, its easy to use, and its free.

To manage your OneDrive, open the File Explorer, right-click OneDrive, and click on Settings.

You can manage all the settings there, including when and where to backup old and unused files. If you want to delete something off of your computer but save it to OneDrive, make sure its synced to the OneDrive cloud before you delete it off of your computer.

Some people spend hours maybe even days trying to clean an infected Windows system and ensuring its actually clean and safe afterward. Its usually not a good idea to do this just reinstall Windows and start over.

This may seem like a daunting task, especially if you dont have good backups of your important files. But its worth it to quickly obliterate an infection and ensure your system is safe.

Clear Your Cache And Cookies

Every time you visit a webpage, your web browser stores or caches it as a small file in your Temporary Internet Files folder. Similarly, it stockpiles small files called ‘cookies’, which contain information about your browsing history and personal details. Over time, the volume of these files can build up. Periodically clearing out your browsers cache will help it to work faster when loading pages and reduce the amount of valuable disk space that these cached files take up.

In most browsers, these settings can be found within the Settings menu, labelled something along the lines of Clear browsing data or Clear cache & cookies.

    If One Piece Of Malware Slips By Your Computer Is Compromised

    RELATED:How to Remove Viruses and Malware on Your Windows PC

    The key to securing your computer is ensuring it doesnt get infected in the first place. Thats why people run antivirus applications that can check programs before they run, ideally preventing a piece of malware from running even once. If malicious software makes it through this protection, it has free rein over your system until its discovered and removed.

    This is a problem for many different reasons. The malware can take this chance to burrow deeper into your system, hiding itself from being discovered by installing a rootkit that starts up during the boot process. It can infect various system files. It can use its access to transmit your personal data, credit card numbers, and passwords over the Internet.

    Worse yet, malware can function as a Trojan horse, opening the floodgates to additional malware that it will download and install from the Internet. If you find your computer is actually infected by a piece of malware, you dont know if thats the only piece of malware thats infected your computer.
