Hi there, I had a virus, as you can can see in this thread: https://www.techspot.com/community/topics/startpins-opening-on-chrome-nsis-error.185801/page-2 ...which resulted in me uninstalling Adobe Flash (as you will read above). I now can't reinstall it. I currently have a version of Flash, as I was able to install it, but it is not the latest version. I try and download it from here: http://get.adobe.com/flashplayer/ I get to stage 4 but then nothing happens. When I try again it says 'Only a single instance of this application can run'. I can't see it open anyway, even when I go to Task Manager. Any help on this would be great. I don't know if this is relvant to this problem, but since getting rid of the virus (my computer is now clean), I now get a pinkish vertical line that comes down the centre right of the screen. It kind of flashes and come and goes. I tried to do a print screen, but it doesn't seem to show up on it. ... Should I start another thread for that issue?!
