1. Remove Viruses, Malware, Spyware, and Adware

It is very important to get rid of viruses on your computer. Every Windows machine is vulnerable to viruses, but, there are no reasons a computer should get infected if you run a full computer scan frequently using an anti-virus program.

Once a computer is infected with a virus, it usually attaches itself to the system memory, utilizing resources that could be useful to other important programs within the system, thus slowing the computer’s performance.

Spyware, on the other hand, can cause pop-ups or trick you into purchasing their anti-spyware programs as well as collecting a user’s personal data without permission.

These are the reasons why you should stop running a computer speed test and remove them since this puts your devices and data at risk.

Spyware can also instruct your device to send destructive emails to your friends, workmates as well as family members. Therefore ensure you install an anti-virus or anti-malware program on your system and scan your computer to eliminate these pesky memory hogs.

2. Free Up Disk Space

During installation and uninstallation as well as storing and removing files spaces are created between the other data on your hard disk.

In the long run, this causes new information not to be saved in blocks but in the nooks and corners of your hard disk.

This makes it difficult for a computer to piece certain parts of the data collected by scoring the hard disk. To defragment your hard disk is to consolidate these files and folders and make them inhabit a single space on the drive.

Ensure you run Disk Defra when:

a. Save a large number of documents in your hard drive.

b. Free disk space gets at 15% or less.

c. You install new, huge software or a new OS.

The Following Procedure Helps to Run the Utility:

a. Stop all active programs and files.

b. Click the Start button and then open Computer.

c. In the computer window that opens, right-click the hard drive that you want to run the utility and then click properties.
