## Testimonials

I purchased Exterminate It! yesterday, as a last ditch effort from having to scratch load an XP Pro workstation, which was infected with the WOWfx Trojan.

In short, your product eliminated all malware on the system. It was the only commercially available product that not only detected the problems, but eliminated them.

For the record, I attempted using:

The registered versions of Spyware Doctor, XSoft Antispyware, CA Antispyware and the free version of Adaware, which all recognized, but failed to clean my system.

Outstanding product.

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

IMPORTANT: Because the registry is a core component of your Windows system, it is strongly recommended that you back up the registry before you begin deleting keys and values. For information about backing up the Windows registry, refer to the Registry Editor online help.

To remove the Sogou registry keys and values:

1. On the Windows Start menu, click Run.
2. 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.
3. 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.
4. 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.

### 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.

Be Aware of the Following Trojan Threats:

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.

Be Aware of the Following Adware Threats:

### Toolbar

A third-party toolbar that provides additional functionality or enhancements for a user’s browser.
Some toolbars are useful; others may camouflage installation of a trojan or spyware to a user’s computer or act as adware bombarding a user with pop-up advertisements.

Be Aware of the Following Toolbar Threats:

## How Did My PC Get Infected with Sogou?^

The following are the most likely reasons why your computer got infected with Sogou:

• Your operating system and Web browser's security settings are too lax.
• You are not following safe Internet surfing and PC practices.

Small-charge or free software applications may come bundled with spyware, adware, or programs like Sogou. Sometimes adware is attached to free software to enable the developers to cover the overhead involved in created the software. Spyware frequently piggybacks on free software into your computer to damage it and steal valuable private information.

### Using Peer-to-Peer Software

The use of peer-to-peer (P2P) programs or other applications using a shared network exposes your system to the risk of unwittingly downloading infected files, including malicious programs like Sogou.

### Visiting Questionable Web Sites

When you visit sites with dubious or objectionable content, trojans-including Sogou, spyware and adware, may well be automatically downloaded and installed onto your computer.

## Detecting Sogou^

The following symptoms signal that your computer is very likely to be infected with Sogou:

### PC is working very slowly

Sogou can seriously slow down your computer. If your PC takes a lot longer than normal to restart or your Internet connection is extremely slow, your computer may well be infected with Sogou.
