I need some Comodo help here .

A few weeks ago, someone mentioned using Ice Dragon as a new browser. Because I am always looking for a better browser, I downloaded it.

The issue is that it seems like Comodo is insidious (I had to delete it a few years ago for similar reasons). The invasive measures are twofold:

1) It gives me no choice over my search engine. If I type a search term in the omnibar that it does not recognize, it brings up a DNS error and other terms. It also shows me that it is searching for the term using Yahoo, which I do not prefer. To see what I mean, search for "brownian" (as in brownian motion). Do you have more success than I (no DNS warning and/or using Yahoo as the search engine)?

2)The Comodo security measures have installed themselves into all of the Firefox browsers. If I use FF or Pale Moon, the same behavior is exhibited. I have no problem with Comodo exerting itself with Ice Dragon, but it is very presumptuous to install itself on my other browsers.

Also, I am getting a pop up now about buying other Comodo packages, etc; both when I log on and at other times when I am using my PC. I have no problems with Comodo trying to make a profit, but these inopportune pop ups are not welcome. I downloaded the free version of their software; if they want to advertise to me via their browser, that is fine. Taking over my desktop is not so fine.

Does anyone know how to solve this? Thanks in advance.
