My computer is slow

After installing a security software there may appear a slight slowdown of the system, which to a certain degree is normal. If you notice a significant slowdown, this easy to follow, step by step guide will help to speed up your computer.


 

1. Multiple antivirus programs

The most probable cause of the situation is that Bitdefender is not the only security program installed on the system.

During the setup, Bitdefender searches and prompts you to remove the security programs found on the system. Having more than one security solution installed on the same PC will cause slowdown, incompatibility issues and the normal action of either one of them is not guaranteed. This is why we recommend our customers to remove any other antivirus programs they may use before installing Bitdefender. For more information, please refer to this article – Uninstall tools for common antivirus software.

 

2. System Requirements

If you removed all the other security solutions from the computer, make sure system requirements for running Bitdefender are met. 

If your machine does not meet the recommended system requirements, the computer will become sluggish, especially when multiple applications are running at the same time. You can find here the system requirements for running Bitdefender.

 

3. Unused programs

Any computer has programs or applications that are not used. And many unwanted programs run in the background taking up disk space and memory. If you do not use a program, uninstall it. This is also valid for any other pre-installed software or trial software you forgot to remove.

Note: If you suspect a program or an application to be an essential part of your operating system, do not remove it and contact Bitdefender Technical Support for assistance.

 

4. Data Corruption, hard disk fragmentation

There could be too many invalid registry keys left in your Windows Registry or your hard disk drives are too fragmented. 

Cleaning the Windows Registry can improve the performance of your system. Also file fragmentation slows down file access and decreases system performance. Running the Disk Defragmenter can improve the performance of your system. You can find the steps to run Disk Defragmenter in this article.

 

5. Your system may be infected

Your system speed and its general behavior can also be affected by malware. Spyware, viruses, Trojans and adware all take a toll on your computer’s performance. Make sure to scan your system periodically, at least once a week. It is recommended to use the Bitdefender System Scan because it scans for all types of malware threatening the security of your system.

To start the System Scan, follow these steps:

• open the Bitdefender window
• access the Protection panel
• under the Antivirus module, select System Scan
• follow the wizard steps

 

Important: If the computer is still slow after following the above steps, please generate a support tool log and send it to our support department so we can assist you in solving the issue ASAP. You can find in this article the steps to generate a support tool log.
