"ask" Removal

Dear,
I have downloaded a few updates files at once and when getting the "gom" videoplayer download stopped. Late on I saw Ask icon on my Fierfox screen. And the browser behave wrongly, tried me to use all the time Ask search, or froze completely. After applying a few programs: Advance System, Care, CCleaner, finally Malwarebytes antimalware identified a P.U.P program with name Ask in title. After deletion Firefox started to work, hopefully, correctly.
At the same time, I had got problems with Pinnacle video editor. I do not know why, but suspect, maybe Ask remained in system and makes problems. I found thread of Chaslang dealing with removal of Ask toolbar, which starts by MG tools. Following the guidence I have downloaded MG tools hoping I would run it and then ask Chaslang or somebody else to assess it.
Unfortunately the MG tools did not work, immediately finished and computer frozen. I even had to switch off computer by stopping power. I did not swich off my antivirus, maybe this could be the problem, but I was simply afreaid to follow.
Can somebody help, first by an advice, is my idea, Ask still acts somewhere in computer and influence programs like Pinnacle?
And second could somebody help to check whether Ask was fully removed from computer or not?
Working with Vaio and WIN 10 (what seems not to be a good combination, but this is not my mometary worry).

Thanks in advance
Ejemmila

 

Many thanks for proposed procedure. I went through it, trying to fulfill exactly all the steps. At the end I have got planned files, which I'll attach to the reply. The behavior of Pinnacle program, however, did not change. Files that I could import before, I still cannot import now. In one of the logs (I do not remember which one) I saw "an ask toolbar" or so, but following yr. instruction I did nothing. I do hope I succeeded to do all correctly and again thanks for help.

Dear Kestrel,
many thanks - it seems my problem with Pinnacle program and Ask tool were solved. Once more thanks to you. I have attached two of three files, you requested. RK file not. I do not know why. I ran Roque Killer twice in a raw. After the first attempt I did not find "Folder" that you asked me to work with. I close the program and ran it again, but I changed language from Czech to English. Only after I understood what place to click. However, the program refused to delete, saying the items were not deleted. I ran RQ yet once more and then the program did not show these two items I was to delete, only three that were before, but I should not check. And again nothing showed on the desktop. Sorry for it. I tried to follow your instruction as accurate as possible. At the end, however, your procedure was a success and thus I thank you once again
Yours Ejemmila
