Are these programs malware?

[IsaacKrementsov]

I installed an app which also installed a bunch of sketchy software, most of which I removed. However, there is one very suspicious program constantly running in the background, which seems to be opening Yahoo search every time I do a Google search (this stops when I close the process in Task Manager). I went to Windows Defender and found that it blocked the scanning of certain files.





Before I try to do this myself, how should I go about removing this? To be sure, is it a virus? Will my computer be damaged if I get rid of it?
