My sister has a very slow Toshiba Satellite C650. It take up to 20 seconds everytime you want to do anything with it. I have tried on several occasions to run spybot, SuperAntiSpyware, ccleaner, MalwareBytes and the machine seems to be better for a day or two by soon returns to its old ways. My guess is the something deeper that keeps manifesting itself. Any help would be greatly appreciated.

It might be browser based malware that the programs you have run don't usually find.

Run these two in the order given:
AdwCleaner:
https://www.malwarebytes.com/adwcle...
Download and "Save" the file somewhere. Go to the saved file then double click it to run the program. Use the "Scan" button, followed by the "Clean" button.

Junkware Removal Tool (JRT)
https://www.malwarebytes.com/junkwa...
Download and "Save" the file somewhere. Go to the saved file then double click it to run JRT. It might appear to have stopped at times or flash the screen but sit tight until it has finished.

It would then be an idea to run MalwareBytes itself once more.

Another possibility is overheating but lets see what the above find first.

Always pop back and let us know the outcome - thanks

Okay I ran both scans followed up with a regular Malware bytes. It looks like there was at least one issue found in a file called c:\appverify.txt which was deleted on the scan. There was also 3 folders listed with Adware.Money.

The regular Malwarebytes scan ran with no issues. Do we just try the computer now for a couple of days and see if things are better?

Also look into programs that were factory installed that you do not need as well as useful programs that start with Windows that do not need to be running all of the time in the background. Uninstall the junk, look at the settings for the good ones and uncheck 'start with Windows' or similar. You can use the start up programs in Ccleaner as well to manage them.

You have to be a little bit crazy to keep you from going insane.

Thanks. I started task manager and the list of processes running is only about 10. We will try the computer for 2 or 3 days and post back the results.

Yes, let us know how you get on.

Sometimes programs that you rarely use can be unchecked in msconfig (from Run box) Startup and worked from a shortcut instead.

My best guess is that it was the malware but we shall see.

Hi, Sorry for the delay. Things have been a bit hectic. I ran Adwcleaner and jrt until everything was clean. The computer seem to be okay for 2 or 3 days, but I used it yesterday and it was brutal again. Any other suggestions to try see whats wrong.

Sometimes malware will hide itself in one or more of your restore points. Try turning off system restore, deleting all restore points. Run your anti-malware and anti-virus programs, removing all infections. Once clean, turn system restore back on and create a new restore point.

Please let us know if you found someone's advice to be helpful.
Failure to install up-to-date anti-virus makes you as much to blame as the virus creators.

I've always had difficulty understanding how a virus in System Restore can activate without running System Restore. However, nothing lost but make sure you save that restore point afterwards as suggested.

When it is slow, open up Task Manager and see what is taking a lot of CPU or Memory (RAM). This might point you to some program that is hogging things. I'm now wondering it if is malware related after all.

Two other things to consider, first do you have more than one antivirus program installed? If you do then they interfere with each other and can cause this problem. This can happen even if you uninstalled one AV program because a normal uninstall often does not completely remove all parts of an antivirus program, you have to look to their web site to see if they have an uninstaller (often hidden) and use that.
Second, when you look at your Task Manager you may see that your antivirus program may be the culprit and is the program hogging your system resources. This happens more often than you might think. McAfee and Norton are both in this category of system hogs, I do not know enough about all of the others to tell you about them.

Hi Guys,

I carried out all the suggestions, turned off system restore, delete all the restore points, and then reran all three scans. The only issue was that JRT wanted to create a restore point, which of course failed. I then turned on system restore and created a system restore point

I then did a disk cleanup including old system files. I am going to also include the jrt and ADW logs just to make sure I didn't miss anything.

I guess we will try the computer again for a couple of days to see how it is.

As you say, nothing there.

You might as well run normal MalwareByte Anti-Malware too. If it is still slow check in Task Manager as per #11 above. Ctrl-Alt-Del will show it.
