I have this new Acer Aspire Z3-710 over a week now and have completed all set-ups (i guess). At first it was all doing great but now whenever i open a File Explorer, point to any folder and right click, the pointer turns into that circle waiting thing and then the opened explorer stops responding. But after a long while of waiting, the rightclick dropdown appears. It takes ages. Please help me on this. I don't think I already got a virus since im still running the free version of McAfee antivirus.
