Welcome to Lunarsoft's PC Cleanup page!

The PC Cleanup page has been converted into a wiki for faster, easier updates. Therefore should there ever be any changes to the programs recommended this page can be updated much faster than before. Also, since the PC Cleanup page is now a wiki version, pages should load faster and images can be loaded separately. When a machine needs to be repaired and is infested with malware, pages do not always load quickly. This is always kept in mind when creating these kind of pages so that even dial-up users may load these pages with ease.

We highly recommend using the Anti-Malware Toolkit to help download the Recommended Software and other useful tools to clean and perform maintenance on your computer.

Cleaning & Settings

This section will describe how to update the recommended applications and allow you to configure each program with the best settings for malware removal.


SpywareBlaster doesn't scan and clean for spyware - it prevents it from ever being installed. It will also stop malware from communicating with its host server. This helps to stop popups and malware from functioning and further spreading the infections.

Update Instructions:

  1. Under "Quick Tasks" click "Download Latest Protection Updates".
  2. Click the "Check for Updates" button.


  1. After updating, click "Protection" near the top.
  2. Under "Quick Tasks" click "Enable All Protection" and you're finished with SpywareBlaster.

CCleaner helps to clean more than just junk files in your computer. It can also help to clean out and remove malware from your %TEMP% folders and other common temporary directories where malware can reside.

Scan Settings:

  1. Select the "Windows" tab and check every option.
  2. Select the "Applications" tab and check every option.
  3. Click the "Run Cleaner" button.
TemplateWarning.png The following items should not be checked.
  • "Memory Dumps"
  • "Windows Log Files"
  • "Old Prefetch Data"
  • "Hotfix Uninstallers"
  • "Advanced" section


  • The Memory Dumps cleaning option will remove any memory dumps that are generated when a program crashes on your computer. Many technicians can use these memory dumps to tell you exactly what caused the crash. These memory dumps are also sent to a crash analysis center at Microsoft when you use the Error Reporting feature. Reporting these errors and sending the crash dumps help all users because hotfixes are often issued to fix the very problem that made the program crash.
  • The Windows Log Files cleaning option will also remove another memory dump file called user.dmp that is generally placed in %ALLUSERSPROFILE%\Application Data\Microsoft\Dr Watson\. This is also useful for technicians to help diagnose errors that cause programs to crash, similar to the Memory Dumps above. In addition, this cleaning option will also remove log files from both program installations and Windows Updates. A user or technician can refer to these generated logs to determine the source of the installation problem if a problem occurs.
  • The Old Prefetch Data cleaning option will decrease your system performance. The impact that cleaning/deleting the prefetch data has on your system is well documented by technicians and Microsoft staff. Prefetch is designed to allow your applications to load faster.
  • XP Only - The Hotfix Uninstallers cleaning option will remove every hotfix uninstaller. This is a bad option for CCleaner to have. If you have this option checked and you remove your hotfix uninstallers, should you ever have an issue with an update (hotfix) from Microsoft, you would not be able to uninstall the problematic hotfix. This could potentially result in your system being crippled.
If you're on Windows 7 and up Microsoft has built in a tool to the Disk Cleanup utility. To access this simply right click on your hard drive (C:) and go to Properties, then click on Disk Cleanup. You can also access this via the Start Menu and going to Accessories - System Tools or by searching for Disk Cleanup. This is much safer than the CCleaner method because Windows will only remove the files that are no longer needed but keep the most recent hotfix files. You can read about it on Microsoft KB2852386.
  • When it comes down to it, you really don't need to have anything in the Advanced section checked. CCleaner doesn't explain any of what it will touch and "clean" for these things, leaving users with a vague assumption of what it will do. Because of this it's hard to safely recommend users have anything under this section checked. It's just not worth having settings and things reset unless you absolutely have to.

Making certain the above options are not checked will ensure your computer remains in proper working order and will have better performance.

Note: The first run can take several minutes. You may wish to uncheck some options if CCleaner takes longer than five minutes.

Advanced users only:

This section deals with changes to your computer's registry. If you do not feel comfortable making changes to your registry then skip this section. It is recommended that you create a folder named "Backups" in your CCleaner folder inside the Program Files directory and save your registry backups there.

  1. Click the "Issues" button and check every option.
  2. Click the "Scan For Issues" button.
  3. Click the "Fix selected issues..." button.
  4. Click "Yes" when asked to backup changes to the registry.
  5. Save the backup for repairing these issues so you may find it easily when you need it in the future.

Would you prefer an alternative to CCleaner? You might like to give the open-source BleachBit disk cleaner a try. It offers explanations of what it cleans and does a very good job with disk cleanup.
