Webuser Forums: Vista - Help Slow PC

I don't see anything untoward there, just to be on the safe side, run these scans and post the results back here.

Please download Malwarebytes' Anti-Malware from Here or Here

Double Click mbam-setup.exe to install the application.

Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
If an update is found, it will download and install the latest version.
Once the program has loaded, select "Perform Quick Scan", then click Scan.
The scan may take some time to finish,so please be patient.
When the scan is complete, click OK, then Show Results to view the results.
Make sure that everything is checked, and click Remove Selected.
When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
Copy&Paste the entire report in your next reply.

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process,if asked to restart the computer,please do so immediately.

Then :-

Download Sophos Anti-Rootkit & save it to your desktop after filling out the questionaire and reading the EULA.

Note: You will need to enter your name, e-mail address and location in order to access the download page.

Double-click sarsfx.exe to extract the files.
Click the Accept button at the EULA, then Install to the default directory
At the next prompt, click Yes to start the program
Make sure the following are checked:[list]
Running processes
Windows Registry
Local Hard Drives

Click the "Start Scan" button.

Allow the program to scan your computer - please be patient as it may take some time

Once the scan has completed a window will pop-up with the results of the scan - click OK to this

In the main window, you will see each of the entries found by the scan (if any)

If the scanner generated any warning messages, please click on each warning and copy and paste the text of it into this thread for me to review
Once you have posted any warning messages here, you can close the scanner and wait for me to get back to you

If you have not had any warnings, any entries which can be cleaned up by the scanner will have a box with a green checkmark in it next to the entry

To clean up these entries click on the Clean up checked items button

If you accidentally check a file NOT recommended for clean up, you will get a warning message and if necessary can re-select the entries you want to clean up
