  • various ways to sort that computer, one could create a new partition, move the files to it and reinstall windows on the main partition. Some Dells have a hidden partition containing the OS restore although some users delete it to free up HDD space. The options listed above-removing a drive to transfer files are also good. In terms of clearing out viruses/malware some online scanners are good like housecall or eset. Malware bytes is good and the fact you can run it means you probably dont have anything serious trying to hijack the OS-those types of infections tend to wreak havoc with permissions. Instances of software that keep appearing after being removed are hard to track down- usually reside in places like hidden folders in Appdata or in randomly named folders on the root or in temp folders. Sometimes you have to use software to force delete them too. Sometimes you can track down a reoccuring install by searching all files ie . and listing by created most recently. Worth checking whats set to run at startup > type config in the windows search function and open system configuration - there you can tick or untick services/programs running as your OS boots up. Theres a handy tool called combofix which is pretty good at repairing the damage done by warez but its only something for techy types that know the risks and have a plan B. Oh and the trackpad may be a hardware fault - ive encountered many dell inspiron with that fault - sometimes its caused by the battery/psu believe it or not.
