Note. This is a self-help guide. Use it at your own risk. This article is provided "as is" and to be used for information purposes.

1.    Before you start, please make sure you are logged as a system administrator. Also, please save a copy of your important documents/files on an external hard drive.

2.    From your desktop, click on Windows Start button and choose Control Panel option (Windows 8 users: right-click on ‘Windows Start’ icon (by default, it is located in the left bottom corner of your screen), and choose Control Panel from the context menu):

•    Click ‘Programs and Features’ (Windows Vista, 7 and 8)/‘Add or Remove Programs’ (Windows XP).

•    Find ‘Optimizer Pro v3.2’ in the list, right-click on it and choose ‘Uninstall’. When a window below opens, please make sure to uncheck box ‘Keep my settings’ before clicking on ‘Yes’:

•    Restart your PC

3.    Please make sure that hidden files in your Windows Explorer are visible: Start –> Control Panel (Appearance and Personalization) –> Folder Options –> ‘View’ tab –> find ‘Hidden files and folders’ and choose an option ‘Show hidden files, folders, and drives’.

4.    Follow this path - C:\Users\YOUR_USER_NAME\AppData\Local\Temp (XP users: C:\Documents and Settings\test\Local Settings\Temp) -> highlight all the files/folders here -> press ‘Shift’+’Delete’ and click ‘Yes’ to completely clean this folder (Note. If you receive messages that some files cannot be removed, just skip the file in question).

5.    Please find the directories below and make sure that all the Optimizer Pro files/folders are removed (you may not find some of the components, it is normal):

C:\Program Files(x86)\Optimizer Pro
C:\Users\YOUR_USER_NAME\Documents\Optimizer Pro
C:\Users\YOUR_USER_NAME\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Optimizer Pro v3.2

6.    Now please remove Optimizer Pro traces from your registry. Before you start, please make sure you understand how important this part of your PC is. You cannot restore data from here once you delete something (‘Ctrl+Z’ never works in Registry Editor). And if you delete an incorrect component by mistake, it may damage your OS and make it unusable.

•    To open the Registry, press ‘Win+R’ keys on your keyboard -> in the opened window type regedit and press ‘Enter’.

•    Highlight main registry section called ‘Computer’ -> press Ctrl+F keys on your keyboard -> make sure Keys, Values, Data boxes in the ‘Find’ window are checked -> type Optimizer Pro in the search field and click OK. Search results will highlight a key/value/data that contains Optimizer Pro components. If you find the exact match with the name of the program you want to remove, right click on the element in question and choose ‘Delete’ from the context menu. If it’s a value/data, right click on the value and choose ‘Modify’, then highlight harmful data and press ‘Delete’ key on your keyboard.

•    Use F3 key to continue the search and to find all the necessary files.

•    Exit the registry editor.

7.    Finally, please install Ad-Aware to make sure you don’t have any infections on your machine:

•    Click here to download Ad-Aware Free Antivirus+, and follow installation instructions from Ad-Aware User Guide (‘Installation and Uninstallation’ -> ‘Ad-Aware Install’ section).

•    Perform a full scan of your PC with Ad-Aware (following Ad-Aware User guide: ‘Scanning System’ -> ‘Running a scan’ section).
