Hi, I would also suggest that you reset internet explorer by going to the advanced tab in the internet options and clicking the reset button. You could later update it again. Also to get rid of this qvo3, you have to right click the internet explorer icon and then click properties and in the shortcut tab in the target box, remove all the entries after "c:programfiles\internet explorer\iexplore.exe and finish it with double quotes. the qvo6 add their https address and codes here for confusing. The entry after your correction should read as "c:programfiles\internet explorer\iexplore.exe"". This is important that i removed this entry to get rid of this tool bar in one computer.Malware bytes by shanes recommendation is the best one, but i would also suggest that do not download software from unknown, and sites like cnet which now is flooded with bundled softwares. I would recommend majorgeeks.com for any download or authors site. Filehippo is one such secured site.
