today, my computer started freaking out, command line started popping up, random internet pop ups, i have not had a pop up in a VERY long time. so first instinct was to run, AVG and lavasoft ad-aware. ad-aware found tracking cookies, only 5 though, AVG found 5 trojans though, AVG cleaned it up and then i thought nothing of it. my laptop started to get really hot and ran really slow, so i pulled up the task manager and it was running at 100%, so i closed everything waited and then turned it off. im the only one that uses it other then my little brother and sister when im there, so i never use a login password... when i started it up again a few hours later, it asked me to enter my password. i didnt even know if i had a password, so i clicked okay, when it went to desktop i saw my desktop image and then a error popped up, i think it was DEP error or something asked me to close message so i did, then the start bar never popped up no folders or files on my desktop and it was just blank, nothin. i cant run anything without going through loops. i managed to get on the internet by going through hp support. i have no idea what to do. please help me soon, im taking instrumentation/automation technology and have software and files that i need for school.
thank you very much for your time
