Some Windows users have been affected by a malware program that imitates Skype software and attempts to steal sensitive information. 65404-SkypeDefenderSetup.exe is classified as an Infostealer, that is, a Trojan horse program that attempts to steal sensitive information such as login credentials.
When executed it displays a confirmation window with the following text, ?Skype-Defender Installed! Please login to your account to apply new plugins?.
there's actually a lot of these programs going around..
they are fake programs, in disguise as software that people normally use
when you type in your login/pass, the info actually gets sent to the person/crook/hacker (whatever you want to call them)
you guys got to be careful, and if you ever download a program, make sure it is from the official website!
