Booting not the problem. When I log on the windows/Icon screen comes up and IMMEDIATELY logs off on it's own. The Icons/program short cuts don't have a chance to come up. No "start" button to click to reset to an earlier time. Just comes up and shuts itself off on it's own.
Trouble started when my mulware id'd a few files that are actually trojans/worms that simulate actual files. deleted these and now my log in-logs out on it's own without giving me time to click on start or any program icon.
