How to remove pop-unders from the browser?

Question

Browsers

I downloaded and installed the HALSetup torrent program, now Opera, FF and IE are full of pop-unders. Together with the program, the Amigo browser and bookmarks from Mile.ru were installed. And processes appeared in the task manager:
50AE.tmp.exe - Description of ZAPCH SOFT INC
7C02.tmp.exe - Description of ZAPCH SOFT INC
ComDev.tmp.exe - Description of ZAPCH SOFT INC
Removed all the programs that were installed today. I checked the computer for viruses - one other web deleted, but there are still ads and processes. And I complete the processes, but they still appear. I have ad blocking enabled.
1. How to remove pop-unders?
2. How to remove mail bookmarks from FF?

Answer 1

Usually this shit is distributed as an "add-on" that does not hide its presence, etc., and therefore is not recognized as malwares, etc. And as a rule, it is removed by disabling it in browser extensions.
Of the antiviruses, IMHO, 360 total sec is better. if under wine.
Although there might be something better.
