"Your skype does not support extended icons. Please download the extension here:
SkypEmoticon is a malware so do not install any kind of new extensions for viewing skype animated icons. Please install the animated icons from well reputed companies do not install them on your friend's request.
Anyways I installed it and it started disturbing my chat as well. It automatically added new line after every sentence and start sending the above blue sentence as well almost with every sentence of emoticon. Surprisingly, no antivirus recognizes it. :(
So here are the following steps to remove it:
1- Uninstall SkypEmoticons from Control Panel -> Add/Remove Programs
but it is still there
2 - So go to your Task Manager
3 - Right click and Open file location like that
4 - As the folder opens, click End task the SkypEmoticons (32 bit) process from task manager and then delete the folder named SkypEmoticons from Roaming folder as in the image. Usually the path is "C:\Users\username\AppData\Roaming\SkypEmoticons"
5 - Now you are free from this malware. :)
