malware !!!

Hello

first sorry for my English it's not my mother language

so lately I've been noticing problems with my laptop, when ever i start a video or a picture it takes so much time to open(the program opens but waiting to load). i'm not an expert when it comes to tech so i tried my best and no luck until one day i opened Task manager and saw Windows Command Processor and console windows host hundreds of them are working here's a picture of it:
Imgur: The most awesome images on the Internet
Imgur: The most awesome images on the Internet

so i don't know what is going on, tried everything i can think of but no luck.

Thank you.
