sudden appearance of mysterious desktop icon in Japanese, cannot delete; shape of a key, round part has percentages (like 40%, always changing) and key thread part has up arrow and 6.4K/s on top and down arrow 28.3K/s. Is this a virus? How to remove it? Can I do a screen shot and send to you, if so how? If I click on this icon, a panel opens up above it, like a menu, with icons and words (choices) in Japanese, which I do not read. Please help. Running Chrome, Windows 8.1, HP PC Compaq. Am relatively computer illiterate but a quick learner. Most grateful.
