Edit: title should read 15gb of ram*

 

Recently I started getting incredible delays with programs on my computer, to the point where it stalls and crashes. When I looked in task manager i was either taskhost, presentationhost, ctfmon.exe, conhost.exe amongst others. There could be upwards of 5 of each of these processes but one of them would always take over 95% of my computers' memory, sometimes up to 15gb of my available ram. 

 

I couldn't terminate these processes as permission was denied, so I used 3rd party software to force terminate them, this temporarily resolved the issue but within minutes another one would spring up taking the same amount of memory.

 

A longer solution was to download malwarebytes software which effectively stopped this happening, but the notifications I was receiving from the software were telling me that every few seconds I was blocking an attack from a random website like 'go.randomdomain.com' and the threat was labelled as 'cftmon.exe' etc. Which suggested that the threat was coming through google chrome.

 

Does anyone have any experience with this? I don't want to rely on this malware removal software as permanent solution, I would like to purge the threat completely. I have reinstalled my browser but I still receive notifications of the threats.

 

Many thanks for the time reading my issue, below is an example taken from my logs from the malware removal software.
