Inactive Trojan causes me to visit unwanted sites!

[Inactive] Trojan causes me to visit unwanted sites!

Hello i have been having some problems with my laptop, i have ran scans and it is showing that it cannot remove an infection called "Bamital.H ". I belive this is downloading other infections as i have removed the same virus/trojans many times. These intruders are causing my laptop to run slowly and is rederecting me to various sites when i click on a web link! Im not exactly a tech wizz but will follow instructions as best as i can, any help would be extremely appreciated!

 

I downloaded the first programme fine but could not open the "malwarebites" programme as it said the files are corrupted

UPDATE: Also seems that i cannot go into task manager anymore via Ctrl+Alt+Del and my laptop is getting very hot!
