How to restore default fonts in the system?

Question

ubuntu

Or maybe it's not the default system fonts. The problem is that after installing ScudCloud, the fonts have changed, and this is noticeably strong in Chrome and some programs that I use for work. I tried to reset the default fonts through the unity tweak tool, and adjust the fonts in Chrome, but both actions did not give tangible results. When installing ScudCloud, there was something that asked if you want to install new fonts, now I regret that I installed it. Maybe in this case you need to understand what fonts he replaced / installed, and remove them?
