Hello all, I have been having issues with my computer recently with a window that pops open, usually looks like two windows simultaneously, and then closes suddenly. Its very disturbing especially while watching movies, series or playing games, the window will just open and close killing the experience, I have also notice a drop in general computer perfomance, I'm using windodws 10, I have looked on the internet for common culprits but no the officetaskhandler.exe application doesn't seem to be the problem as firstly I don't even have Microsoft office installed, but also I checked for the task Task Scheduler and it doesnt exist, I don't know if I have a virus or what, please help.
