I downloaded Malwarebytes to run a scan of my system. After it had detected some threats, It removed/quarantined all the threats it had found. I use Firefox & have been happy with it & have the latest version - 25.0.. I have since uninstalled it but my system loads very slow & all programs are affected including videos, etc.. The system was fine before this was done.

Hello wbielby,

Nearly every Antivirus program is slowing your pc, because Antivirus programms always work in the background. To make your computer faster deinstall your antivirus programm. Be sure that you are not safe without a antivirus system.

My whole computer is slow to come up also. It only started after running Malwarebytes Anti-Malware program & removing threats. My Norton has always been running before this program was installed & ran. It has been uninstalled (Malwarebytes Anti-Malware)but still not working right.

Go to task-manager (2nd bar) and look wich programs are using the most RAM. If you need help, just post a screen of the task-manager and I will help you.

Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.


Did you try other malware scanners in case you are still infected?

Do a malware check with some malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.
All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.

I have/had this exact problem -I just restored everything that Malwarebites "quarantined" (an option within the program), and it honestly seems better already. My wireless network connection was even restored and is working well again (after running Malwarebites the connection wouldn't automatically connect after sleeping as it did before).

My guess is, Malwarebites isn't so good at differentiating good from bad.

I've only been running the PC for about 20 minutes since restoring everything, but I've noticed improvements in everything (especially boot up). I'll update this if my results change, but as of now it seems to have fixed the problem.

  • update -after restoring the quarantined items and removing the program from my PC everything seems to be running at it's original speed. Firefox, Photoshop, and Dreamweaver are all opening and running at near instant speeds (as they originally did).
