How to remove SysDefence (Uninstall instructions)

Myantispyware team December 17, 2009     No Comment    

SysDefenceSysDefence is a rogue antispyware program that installed through the use of trojans that come from fake online malware scanners or misleading websites that ask users to install a fake codec or an update of Flash Player needed to view a video online. When the trojan is installed, it will download and install SysDefence onto your computer and configure it to run automatically when Windows starts.

When running, SysDefence will perform a fake system scan. It states that your computer is infected with trojans, adware or malware and that you should purchase the program to remove these infections. Of course, this is nothing more but a scam, because SysDefence identifies harmless files as dangerous infections. So, the scan results are fake and you may easily ignore them.

Last, but not least, the same trojan that installs SysDefence will download and install a variant of trojan FakeAlert. When the trojan is running, you will see fake Windows Security Center and fake security notifications, that stats:

Spyware Alert!
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 SysDefence and remove spyware
threats from your PC.

Of course, all of these alerts are fake and like false scan results should be ignored!

So please ignore all that SysDefence gives you and remove it upon detection. Use the removal guide below to remove this malware for free.
