After scanning my computer many times using big name anti-virus and malware programs I still had several problems. Finally "Exterminate It" found multiple infections from NetSky. I sent Exterminate It a sample and the next day I received an e-mail instructing me to update and rescan. After following the instructions ZAP the worm/trojan was gone. My computer seems to be completly back to normal now. Good Job Exterminate It!

How to Remove OpenSite 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 OpenSite from your Windows registry, you must delete all the registry keys and values associated with OpenSite, which are listed in the Registry Keys and Registry Values sections on this page.
To remove the OpenSite 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.

OpenSite Categorized as:
Adware
Software that is designed to launch advertisements, frequently pop-up ads, on a user’s computer and/or to redirect search results to promotional Web sites. Adware programs are often built into freeware or shareware programs, where the adware creates an indirect ‘charge’ for using the free program. Sometimes a trojan can silently download an adware program from a Web site and install it onto a user’s machine.
Hacker tools, or Browser Hijackers, can also download an adware program by exploiting a web browser’s vulnerability. Browser Hijackers may tamper with the browser settings, redirect incorrect or incomplete URLs to unwanted Web sites, or change the default home page. They can also re-direct a user’s searches to “pay-to-view” (often pornographic) Web sites.
Typically, many adware programs do not leave any marks of their presence in the system: they are not listed on Start | Programs; they add no icons to the system tray; and they don’t show up on the task list. In addition, adware programs seldom provide an uninstallation procedure, and attempts at manually removing them frequently result in failure of the original carrier program.
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.
Hijacker
Software that seizes control of a computer’s resources to proliferate itself or use them for other malicious purposes.
There are several types of hijackers. The most common are:
- Browser hijackers – Alters the existing Internet browser settings so that a user is redirected to unwanted or malicious Web sites. These include programs that change the browser Home page or replace a popular search service’s home page with its own fake copy, whose search results point to particular malicious or irrelevant sites.
- Autorun hijackers – Automatically run certain programs on start-up of a user’s computer.

Downloading and Installing Freeware or Shareware
Small-charge or free software applications may come bundled with spyware, adware, or programs like OpenSite.

Spyware frequently piggybacks on free software into your computer to damage it and steal valuable private information.
