SecureDefense is a rogue anti-spyware from the Wini family of fake security programs. This programs is distributed through malware that pretends to be a video codec or via fake online anti-malware scanners that state your computer is infected. When the program is installed it will be configured to start automatically when Windows starts. While installing , SecureDefense will also create hundreds of fake and harmless malware files. These fake malware files are then detected as infections when SecureDefense scans your computer. The program will not remove them, though, until you purchase it. This is a scam as the files it detects are the files it created on your computer in the first place. Therefore do not be concerned by any of its scan results.
When SecureDefense is running it will also display a fake Windows Security Center window. This window will look exactly like the legitimate Windows Security Center, except that it suggests that you purchase SecureDefense to protect your computer. While SecureDefense is running it will also display fake security warnings and alerts that are designed to make you think that your computer has a serious computer problem or is under attack from a remote program. The text of these messages are:
Security Center Alert!
Your computer is being attacked by an Internet Virus. It could be a password-stealing attack, a trojan-dropper or similar.
Do you want SecureDefense to block this attack?
Your computer is infected with spyware. It could damage your critical files or expose your private data on the Internet. Click here to register your copy of SecureDefense and remove spyware threats from your PC.
Just like the fake scan results, these security alerts are all fake and should be ignored.
When infected with SecureDefense, Internet Explorer will become hijacked so that it displays warning messages when you browse the web. These messages are designed to make you think that the web sites you are visiting are insecure and that purchasing SecureDefense will protect your computer from being infected. The warning message that you will see is:
Reported Insecure Browsing: Navigation blocked
Insecure Internet activity. Thread of virus attack
Due to insecure Internet browsing your PC can easily get infected with viruses, worms and trojans without your knowledge, and that can lead to system slowdown, freezes, and crashes. Also insecure Internet activity can result in revealing your personal information. To get full advanced real-time protection for PC and Internet activity, register SecureDefense.

This is just another scare tactic being used by the program and can be ignored.
As you can see, SecureDefense was designed to scare you into purchasing it by display fake scan results, fake security alerts, and browser hijackings. It goes without saying that you should definitely not purchase SecureDefense, and if you already have, please contact your credit card company and state that the program is a computer infection and a scam and that you would like to dispute the charge. To remove this infection and any related malware, please follow the steps in the guide below.

location and save it to your desktop:
Malwarebytes Anti-Malware Download Link (Download page will open in a new window)
- Once downloaded, close all programs and Windows on your computer, including

Please click on the Scan Now button to start the scan. If there is an update available for Malwarebytes it will automatically download and install it before performing the scan.
- MBAM will now start scanning your computer for malware. This process can
take quite a while, so we suggest you do something else and periodically
check on the status of the scan to see when it is finished.
- When MBAM is finished scanning it will display a screen that displays any malware that it has detected. Please note that the infections found may be different
than what is shown in the image below due to the guide being updated for newer versions of MBAM.

When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so. Once your computer has rebooted, and you are logged in, please continue with the rest of the steps.
- You can now exit the MBAM program.
- As many rogues and other malware are installed through vulnerabilities found
in out-dated and insecure programs, it is strongly suggested that you use
Secunia PSI to scan for vulnerable programs on your computer. A tutorial on
how to use Secunia PSI to scan for vulnerable programs can be found here:
How to detect vulnerable and out-dated programs using Secunia Personal Software Inspector
Your computer should now be free of the SecureDefense program. If your current anti-virus solution let this infection through, you may want to consider purchasing the PRO version of Malwarebytes Anti-Malware to protect against these types of threats in the future.
