For the past few weeks, my cursor has randomly started clicking without even touching my mouse or touchpad. At first, I thought it was my mouse as it was quite a few years old, however, I got a brand new mouse and the problem is still happening and it's very hard to type when my mouse randomly clicks off of the area where I'm typing or if it's hovering in the paragraph above the current one, clicks there and I start typing in the middle of something I've already written. I've run AVG and Malewarebyte's Anti-Maleware and they come up clean, so it's not a virus that's causing this. I'm at my wit's end about this; the problem comes and goes, but when it's really acting up I can barely type two words without it spazzing out. I have a Dell Laptop, Inspiron 1720 with Windows Vista. Please help, thanks!
