My Gateway laptop has slowed to a crawl over the past couple of months. There has been no change in software demands or workload, but I suspect malware infestation. I have tried Ad-Aware, AVG antivirus, and PC-MATIC, nothing has helped performance. Internet Explorer pops up window denoting "long running script" and asks to stop script or continue, as does Facebook. Most programs show crawler box at bottom of screen " XXX (program which is executing) is not responding" . If I do nothing the program will eventually execute. Looking at Task Manager reveals no mystery programs running.
What I would like is help finding just what is causing the "long running script" pop-up and perhaps a "triage list" on how to go about identifying services or processes that may be running in the background that have nothing to do with the desired executables.
