Other factors that could slow down the system
- Antivirus programs on a system disprove the saying “Better safe than sorry”. Two antiviruses running simultaneously might see each other as malicious and their real-time protection may cause conflicts during scanning. Using multiple antivirus programs will even further weaken your computer's performance.
Note
Windows Defender Antivirus is automatically installed and active on all Windows 10 operating systems. Windows Defender is automatically disabled when a non-Microsoft antivirus program is installed.
- Over time, the amount of unnecessary data on your device such as registry entries of uninstalled programs, junk files, unwanted toolbars, and adware may increase. You can use optimization software to clean up the junk files and optimize your drive.
- Bugs and vulnerabilities in software can also lead to computer slowdowns. Make sure your operating system and programs are up to date.
