How to Clean Up a Slow Computer

Many of us assume that when our computer starts running slowly, it's time to buy a new one. Does your computer freeze for minutes at a time? Does it struggle to open files or programs, and take a long time to boot up? Even if you've been diligent in using your computer and avoid downloading suspicious files, over time, your system will inevitably accumulate unnecessary registry entries, errors, junk, and debris. It's crucial to clean up your computer to restore its speed and efficiency.

Update your antivirus software and perform a full system scan. Antivirus software helps protect your computer from viruses and other suspicious files that can spread by simply opening an email. The software regularly checks the system and identifies any strange files attempting to infiltrate your computer.

• Norton and Kaspersky are popular antivirus programs, typically costing around 500,000 VND.
• Avoid using Registry Optimizers or so-called Clean Reg Tools. Most of these programs do more harm than good to your computer in the long run.

Download and install anti-spyware software. This type of malicious software is installed on your computer to secretly monitor specific information without your knowledge. To maintain your computer's security and health, it is recommended to remove spyware and other "malicious software".

• You can download free anti-spyware programs for your computer. Once downloaded, install and run the program; if you're not familiar with using a computer, follow the instructions provided.

• Be cautious when installing software; many free programs found on certain websites could be spyware, malware, adware, or even viruses. Only visit trusted websites and use Google for recommendations.
• Avoid installing software that you don’t use frequently.
• To ensure secure internet browsing, install a firewall (Microsoft includes a built-in program on all Windows computers) or purchase an external firewall router.
• Defragment your computer monthly. Over-defragmenting can significantly reduce your hard drive’s lifespan due to constant writing, deleting, and re-writing of files. Once the hard drive is damaged, it’s impossible to recover data, so proceed with caution.
• Use CCleaner.
• Regularly scan for spyware and viruses: weekly if you rarely download files or programs, or daily if you download frequently.

• When uninstalling programs, ensure you no longer need them; some programs are essential for your computer’s functionality.
• Never defragment a computer with a Solid State Drive (SSD), as it could lead to file corruption.
• When using anti-spyware software, follow instructions carefully. These programs modify system registry settings, and improper usage could slow down your computer. If you’re not tech-savvy, only delete red-marked items or seek advice from a knowledgeable friend.
