Specs: Windows 7, Intel p6100 2.0 Ghz/4GB
I have finally got a old laptop working so my sister can use it temporarily while I try fix hers. The erfomance is terrible. No matter what you might be doing on the computer is can take up to 20 seconds or longer to do things. Internet is especially slow.

I have run all the normal tools (ccleaner, malwarebytes, superantispyware, spybot) and it hasn't fixed. I am hoping some of you experts can help me identify if there is a deep embedded virus or malware.

Interesting I filled that all out at the bottom of the screen. I guess it doesn't get included.

It is a Toshiba Satellite C650 - intel p6100 @ 2Ghz / 4GB memory - Windows 7

No doubt it will be cluttered with assorted junk files, stuff possibly running in the background; assorted pestware.

Besides having run ccleaner,mawarebytes

also run


Also ensure you have a current/up to date antivirus package installed.

There are free version such as Avast, Kaspersky, Bitdefender; all safe to use

and many users are very happy with M$-land own version

Also check what's loaded at boot up -

and see if there things that didn't ought to be there etc...

Having done the above... hang about for more input from the "windows get it working properly" gurus...

Also ensure you don't "ever"use the automatic/default installation option for anything installed off the web. Use manual/custom mode and watch for and uncheck any pre checked boxes apart from the one for item required. That way assorted pest and changes will be avoided; many being a true PIA rto eradicate, and can be buried deep in the system files.

Check if the HHD is more than 2/3 full. Delete whatever is not needed including unused applications.

To address the internet performance, this could help:
Winsock Reset in Windows 7

1. Open the Start menu by clicking the orb in the bottom left-hand corner of the screen.

2. Type “cmd” in the search bar at the bottom of the menu.

3. Right-click on cmd in the search results for Programs, and select Run as administrator. Depending on your computer settings, you may be asked to provide an administrator password before you can continue.
4. Enter "winsock reset"

5. Wait for the Command Prompt to run through the reset. Once it’s complete, you’ll see the message “Winsock reset completed successfully”.

6. Restart your computer to finish.

I downloaded the latest version of AdwCleaner (7.4.2) and it indeed dod find some things that it cleaned up. I second run now shows things are clean. Awcleaner also gave me a list of pre-instaled software. It was all from Toshiba so I didn’t delete any of it.

I then reran my usual stuff t make sure all was clean (ccleaner, Malwarebytes, spybot, and superantispyware). I d have MSE on the computer as the virus scanner and I am in the middle of running it now.

Not sure what normal is but it took over 30 minutes to update the definitions. After that I finally left it overnight and went to bed.

As for removing unneeded programs from starting is msconfig the way to go. My experience in the past has been that when I d that, I always get a warning message when I boot up. It has been a while so maybe I am getting confused with something else. In addition I noticed that there are other things like Malwarebytes that are not included. You ave to right click on the system tray icon and tell it not to start when windows starts.

I agree. I have told my sister to be very careful when doing updates to make sure no extra software is being installed. I know adobe used to always want to install Mcafee, but I noticed the last view times it is unchecked by default, but you always have to be careful and look twice, if not three times.


The hard drive has 72GB used out of 267, so lots of room left.

I am reading in correctly or did you miss the command to actually do the winsock reset at the command prompt? Is it just Winsock reset?

Since you have CCleaner installed, I believe that it has the feature to manage start up programs.
Otherwise you go to the settings on each program and look for the "Start with Windows" and uncheck or disable the option.

You can usually remove most of the programs that are included at the factory except the once you use and programs related to hardware. For the ones you are not sure of, you can Google them to see their purpose and usually find opinions on how necessary they are to the system included in the search results.

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

hi everyone,

Thanks for all the suggestions. I have finished them all but it still seems like there are issues. Last night when I finished everything, things were looking better. At least the computer was responding better. I decided to do some work to see how it was over the long term.

Using MS Excel caused some issues right away. Simply clicking on the top corner to highlight the entire sheet so I could change the font caused me to be presented with the spinning wheel and even a notice at the top that excel was not responding.Other movements within excel caused the same type of issue, although I have to admit it seemed better than before, where the computer was almost unusable.

Tonight I started up the computer and maybe I didn't wait long enough which compounded the issue, but when I thought Windows startup had completed I tried to start Chrome. It tool well over 2 minutes for it to finally come up. Looking at task manager some processes were running as high as 67%. At this point I killed Chrome processes. I might add at this point that it seems when you start Chrome it actually starts 3 or 4 processes. Is this normal? The processes with high CPU utilization were;


Finally I got tired of waiting for the processes to die down so I restarted windows. This time everything was calm within a short period of time, and I was able to open Chrome to provide this update without incident.

As I have continued to use Excel tonight, I have found it keeps freezing. I finally decided to start task manager and watch it. Every 10 -15 seconds I can see TrustedInstaller runs and takes about 40-50 cpu.

Booted up the computer this morning and received this.

Failed To Connect to a windows service

Windows could not connect to the System Event Notification Service service. The problem present standard users from logging onto the system. As an administrative user, you can review the System Event log for details about why the service didn’t respond

Have been reading on google about problems with TrustedInstaller and it seems related to windows update modules. In fact yesterday or the day before I did see that windows updates were downloading. Today it wasn't so I decided to try go do it manually. There were two critical updates so I picked them both. Currently the Install of >Net Framework 4.8 has been sitting for more than 30 minutes and the progress bar has not moved at all.

Okay I scared it. I no longer had ht enter on this computer when I looked back at the other computer and now see the install is about 60% done. I have some non-critical updates to apply where I can keep track of the exact time. If TrustedInstaller has to keep running because updates are taking a long time, that might explain the issue this computer is having. It doesn't seem to be often but there are times when it runs well. I actually accessed it one with TeamViewer and the response was better that if I was at my sisters sitting right in front of the computer.

So every update I run seems to fail on an error code. Of course I didn't write it dwn so I will have to run another one to get it. What I have been trying in the mean time is doing a 'check updates' and then manually downloading from and then installing them stand-alone. Howver this process seems to be taking hours to do each KB.

Unless someone else has some suggestions, I am wondering if I might have to restore the computer back to its original settings.

Run it in Safe Mode and see if it behaves totally different, or quite the same

I realized when I got to safe mode I wasn't sure if you meant try windows update or try installing the KB stand-alone. I tried Windows update from the start winduw 3 times but it never started up or did anything. I looked in control panel and realized windows update is not there so maybe it is not available in safe mode.

I tried installing the KB from the downloads directory but I get a the following message;

Installer encountered an error: 0x8007043c

This service cannot be started in safe mode

Update: It seems I have stopped the TrustedInstaller from running all the time. When I first ran Adwcleaner, it found 6 pip entries. I was sure I cleaned them and reran the scan and it came clean. However today I thought I would run all my scans again. When I ran Adwcleaner it had an update to version 8.0 which I downloaded and ran. Imagine my surprise when it again found 6 pup entries. I cleaned them again, rebooted, and now I am happy to report that I no longer see the TrustedInstaller process running every 10-15 seconds.

However I still can't do any Windows updates. Can someone help me with that here or should I start another post.

I have had good results using Windows repair to fix Windows Update and other corrupted system files and features. You run it in Safe Mode after downloading it, I recommend running all recommended pre scan items first.
