I am attempting to clean up a friends HP PC which is running Vista 32 bit SP2. I believe she has contracted a piece of malware by clicking on a photo in facebook (Is this a picture of you?). One of the symptoms is preventing the computer installing updates for Vista and Defender. I have downloaded the Malicious Software Removal tool from MS and I am running full scans on Malwarebytes, AVAST and spydoctor. However, when booting up the taskbar icon for safely removing hardware always shows multiple drives attached (F,G,H,I,J,K,L) which all safely eject. I am wondering is there a way of preventing this occuring on boot up? Also any experience of the malware issue would be very useful.
