Hi,
I'm very happy with your performance. I'll be a customer for life. Winctrl32.dll has gone. I have 4 other Bought and Paid for Malware programs
that I have but none are as good as yours and none have the same individual response times as good as
yours. Some do not respond to help At All.
Great job!

How to Remove LinkReplacer from the Windows Registry
The Windows registry stores important system information such as system preferences, user settings, and installed programs details as well as the information about the applications that are automatically run at start-up. Because of this, spyware, malware, and adware often store references to their own files in your Windows registry so that they can automatically launch every time you start up your computer.
To effectively remove LinkReplacer from your Windows registry, you must delete all the registry keys and values associated with LinkReplacer, which are listed in the Registry Keys and Registry Values sections on this page.
To remove the LinkReplacer registry keys and values:
- On the Windows Start menu, click Run.
- In the Open box, type regedit and click OK.
The Registry Editor window opens. This window consists of two panes. The left pane displays folders that represent the registry keys arranged in hierarchical order. The right one lists the registry values of the currently selected registry key. - To delete each registry key listed in the Registry Keys section, do the following:
- Locate the key in the left pane of the Registry Editor window by sequentially expanding the folders according to the path indicated in the Registry Keys section. For example, if the path of a registry key is HKEY_LOCAL_MACHINE\software\FolderA\FolderB\KeyName1, sequentially expand the HKEY_LOCAL_MACHINE, software, FolderA, and FolderB folders.
- Select the key name indicated at the end of the path (KeyName1 in the example above).
- Right-click the key name and select Delete on the menu.
- Click Yes in the Confirm Key Delete dialog box.
- To delete each registry value listed in the Registry Values section, do the following:
- Display the value in the right pane of the Registry Editor window by sequentially expanding the folders in the left pane according to the path indicated in the Registry Values section and selecting the specified key name. For example, if the path of a registry value is HKEY_LOCAL_MACHINE\software\FolderA\FolderB\KeyName2\,valueC=, sequentially expand the HKEY_LOCAL_MACHINE, software, FolderA, and FolderB folders and select the KeyName2 key to display the valueC value in the right pane.
- In the right pane, select the value name indicated after a comma at the end of the path (valueC in the example above).
- Right-click the value name and select Delete on the menu.
- Click Yes in the Confirm Value Delete dialog box.

LinkReplacer Categorized as:
Trojan
A trojan is a program that is disguised as legitimate software but is designed to carry out some harmful actions on the infected computer.
Unlike viruses and worms, trojans don’t replicate but they can be just as destructive.
These days trojans are very common. Trojans are divided into a number different categories based on their function or type of damage.
BHO
Browser Helper Object, or BHO, is a dynamic link library (DLL) that runs whenever Internet Explorer is started. Generally, BHOs are included in installation of third-party programs where they are offered as enhancements of the browser functionality. For example, many Internet Explorer plug-ins are in essence BHOs.
BHOs can be installed silently or “legitimately” when a user fails to read the fine print included in the freeware program’s EULA (End User License Agreement).
Because BHOs are small programs, they can do anything that other programs can do. It’s not easy to detect the BHOs installed on the computer. This enables hackers and other malevolent users to employ the BHO functionality in their interests, for example, secretly install adware programs or gather various statistics on the user’s browsing trends.
