How to Detect & Remove IEDefender
What's IEDefender?
IEDefender may be the latest rogue anti-spyware. IEDefender may popup exaggerated security alerts to try and trick you into buying IEDefender. IEDefender may have downloaded itself onto your computer through a trojan, like Zlob. IEDefender may launch when you start up Windows, and IEDefender may cause excessive popup ads that are difficult to close. IEDefender may also act as a browser helper object — or BHO — that may hijack your searches on Yahoo! and Google, and popup alerts that your computer is infected. IEDefender’s fake alerts may read:
“Google Alert!
Your computer is infected! Some of your search results were changed by spyware. You have to clean your pc and we recommend to use our ANTISPYWARE!”
That great grammar — sarcasm, yes — tells you a bit about IEDefender. Remove IEDefender, if only because IEDefender may make you want to throw your PC out the window. IEDefender.com

Note: In any files I mention above, “%System%” is a variable referring to your PC’s System folder. Maybe you renamed it, but by default your System folder is “C:\Windows\System32″ on Windows XP, “C:\Winnt\System32″ on Windows NT/2000,” or “C:\Windows\System” on Windows 95/98/Me.
“%Program_Files%”, “%ProgramFiles%”, or “%Profile%” is a variable referring to a folder in your PC where applications that aren’t a part of your PC’s operating system are installed by default. You may have changed this folder’s name or moved it, but if you didn’t touch it, find the folder as “C:\Program Files”. If you’re having trouble finding this folder, you can locate it by looking up registry value “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ProgramFilesDir”.
Also, “%UserProfile%” is a variable referring to your current user’s profile folder. If you’re using Windows NT/2000/XP, by default this is “C:\Documents and Settings\[CURRENT USER]” (e.g., “C:\Documents and Settings\JoeSmith”).
IEDefender changed your homepage?
Click Windows Start menu > Control Panel > Internet Options. Next, under Home Page, select the General > Use Default. Type in the URL you want as your home page (e.g., “http://www.homepage.com”). Then select Apply > OK. You’ll want to open a fresh web page and make sure that your new default home page pops up.

To save time and avoid risking destroying your computer, I highly recommend you use a spyware scanner, such as SpyHunter, to detect IEDefender and other spyware, adware, trojans, viruses, keyloggers, and more that can be hidden in your PC. It’s also recommended before you manually remove IEDefender you backup your system.

How Did I Get IEDefender?
You may be wondering how IEDefender ended up on your PC. If you’re infected with IEDefender or other spyware, your system’s and web browser’s security settings may be set too low, you may not follow safe web browsing and email habits, and you may need to regularly use a good anti-spyware application. Unsafe computer behavior that may lead to your PC having IEDefender includes:
Freeware or Shareware:
Did you download and install shareware or freeware? These low-cost or free software applications may come bundled with spyware, adware, or programs like IEDefender. Sometimes adware is attached to the free software to “pay” developers for the cost of creating the software, and more often spyware is secretly and maliciously attached to free software to harm your computer and steal your personal and financial information.
Peer-to-Peer Software:
Do you use a peer-to-peer (P2P) program or other application with a shared network? When you use these applications, you put your system at risk for unknowingly downloading an infected file, including applications like IEDefender.
Questionable Websites: Did you visit a website that’s of questionable nature? When you visit malicious sites that are fishy and phishy, Trojans, spyware, and adware may be automatically downloaded and installed onto your computer, sometimes including applications like IEDefender.
It’s important to practice safer online habits to prevent being infected with IEDefender . You may want to scan your computer for the latest version of IEDefender and other security threats.

When you’re infected with malware, whether it’s IEDefender, spyware, adware, trojans, rogue anti-spyware, keyloggers, worms, or viruses, there are a few key symptoms you may experience. If you notice one or more of the symptoms listed below, your PC may be infected with IEDefender or other malware. Continue reading below, or click here for a free malware scan.
Slow computer performance: It only takes one or two spyware parasites like IEDefender to cause your computer to slow dramatically. If your PC takes longer than usual to reboot or if your Internet connection is unusually slow, your computer may be infected with malware.

Understanding IEDefender & Spyware
If you’re infected with IEDefender and spyware, you should know what you’re fighting. I’ll explain some spyware definitions related to IEDefender.
IEDefender May Be Rogue Anti-Spyware
What’s Rogue Anti-Spyware?
Rogue anti-spyware - or suspect anti-spyware - refers to anti-spyware software of questionable value. Rogue anti-spyware may not be proven to protect your computer from spyware, may popup fake alerts or create many false positives about your PC being infected, or may use scare tactics to try to get you to purchase the application. Rogue anti-spyware software may be installed by a Trojan, come bundled with other software, or install itself through web browser security holes. While it is fairly rare, some rogue anti-spyware is created and distributed by known spyware or adware companies, and the rogue anti-spyware may install spyware or adware itself.
Often when you’re infected with rogue anti-spyware like IEDefender, you’ll see a false popup security alert like this:

Rogue Anti-Spyware Tactics
Typically, rogue anti-spyware has one or more of the qualities listed below, which is why rogue anti-spyware is considered anti-spyware software of questionable value.
» False positives/fake alerts: Rogue anti-spyware may produce a large number of false positives or use fake alerts, noting that your computer is infected with spyware parasites or other threats that do not really exist.
» Copycat looks: Rogue anti-spyware may copy the look and feel of other legitimate or rogue anti-spyware applications. Often, rogue anti-spyware applications may appear as close clones of other rogue anti-spyware software.
» High pressure marketing: Rogue anti-spyware may use scare tactics or other aggressive advertising and marketing tactics to try to trick you into buying the rogue anti-spyware application. Often, rogue anti-spyware may produce false positives and fake alerts about your computer being infected.
» Poor detection/scan reporting: Rogue anti-spyware may produce poor reports when it scans your PC. For example, rogue anti-spyware may say your computer is infected 11 parasites, but not specify which spyware parasites or what type of parasites. Rogue anti-spyware may also report that your PC is infected with SafeAndClean, but not tell you which related files, DLLS, etc. were found on your computer.
» Weak scanning/detection: Rogue anti-spyware may not only poorly report on computer infection, but rogue antispyware may also poorly scan your PC. Rogue anti-spyware may skip over important folders and files of your computer that should be scanned to detect spyware.
IEDefender may use these tactics to trick or scare you into purchasing IEDefender.
IEDefender May Be a Browser Helper Object
What are Browser Helper Objects?
Browser helper objects (BHO) are often created by website authors to customize and control Internet Explorer and the way websites appear on IE. Browser helper objects usually load when Internet Explorer starts up, and BHO’s may share IE’s memory and perform various actions on any available windows and modules. It’s possible for browser helper objects to detect events, create additional windows to display information, and monitor your messages and actions.
IEDefender may act this way, and depending on the activities of IEDefender, IEDefender may range from simply annoying to a threat to your privacy and your system’s stability and security.
Some browser helper objects may also fall under the category of spyware. Spyware is any software or malware (”malicious software”) used to spy or track your computer activity. While some spyware is legitimately and intentionally installed by parents or employers to monitor Internet activity on a computer, spyware may be installed maliciously. Often spyware may come bundled with downloads of free software or come in the form of a cookie via a website, and this spyware may track your Internet activity or may steal secret account usernames and passwords, credit card numbers, and other personal and financial information.
