Notepad file opens on startup

Long story short, a friend of mine borrowed my laptop to complete his essay, since his computer ‘broke’.
So now, everytime I startup my laptop and login, a notepard file opens up with a bunch passwords for p0rn sites.
I’ve tried using CCleaner to see if it is a startup file, but it doesnt seem to be.
Any ideas?
Answer #1
I guess you could just delete the said text file.
If any of the content is of interest, copy it to somewhere else.
Answer #2
System restore to before you lent it to him if you can.
Answer #3
I’ve tried system restore, but that hasn’t fixed it.
Also, I don’t have a clue where that file is, so I can’t delete it. I’ve tried simply deleting the contents of it and pressing ‘save’ but they re-appear on my next restart.
Answer #4
Maybe u need full scan with malware bytes
off topic did u ask ur freind these naughty passwords pop up when ever I start my laptop since u took it lol
Answer #5
When it’s open, click on ‘save as’.
You don’t need to actually save it as anything, but this should reveal where it’s located.
Answer #6
Right click on it and Properties should tell you where it is.
And as suggests, do a complete scan with your anti virus software.
Answer #7
Can you go to RUN -> MSCONFIG -> Startup and see if he has hooked up something?
