As stated above, I'm a novice. The laptop in question is an older Gateway running Vista that my daughter uses for homeschool. The malware (rootkit??) would not go away with malwarebytes, and since detecting and "Fixing" it with AVG, the cursor is locked and I do not know where to go from here. Thank you so much for your assistance, and again, I apologize if I am not describing this well.
(I was unable to run the OTL or aswMBR, as I cannot get into her laptop.)
