Please rafaelluik nothing you listed is malicious. They are mere toolbars installed by your own mother. I know every one you listed. Upload them to Virustotal and see for yourself. I have been working as a system engineer for awhile now. I also run home business making house calls. Mainly malware removal. I see things like the famous “FBI Randsomeware” which holds your pc at ransom and makes it completely unusable. I can understand that your frustrated that the Avast Browser cleanup missed this toolbars. But again NOTHING finds everything. Thats why there are so many scanners on the market. Avast misses things. Norton misses things. McAfee misses things. That’s why there is MBAM,SAS,HMP and other various on demand scanners. So go ahead and remove these toolbars. In another month they will be back until you educate your mother on how they got there in the first place.
