Laughing Baby

By Steven Bene

  1. I recently fixed a 2007 Compaq presario f700. After a week, I have a virus I think is very bad. It doesn't let me boot in safe mode. When it turns on, music plays on the login screen. When I log in, it plays the sound of a laughing Baby. It also installed about 8 programs I have never heard of. If I open ANY browser, my computer shuts down and restarts. It won't do anything accept display the desktop and a virus scanning software I didn't download. It was working beautifully with 4gb ram, tiny hard drive, and WINDOWS 10! It originally had vista. I have two of the same laptops, so I have all spare parts other than a motherboard. I took out the hard drive and replaced it and am scanning the computer itself. When the sounds were playing, my speakers were muted. Please help. I am getting a new laptop in July, but I want this one fixed.

    How big of a flash drive? I have an external hard drive, but it is the whole family's and I don't want to mess it up. I put in a hard drive I had laying around and it works fine. I scanned the whole computer, not just the hard drive, and nothing came up. I am almost positive that it is contained on the other hard drive. Also it isn't too much of an issue to me because I am getting a new laptop for school this summer. I will still use this until it dies though. I already fixed it. An IT guy couldn't even fix it. I hope I can save the drive, but if I cant my computer runs fine for now. If this is no longer worth your time, knowing I can still use my computer and I am using a different hard drive, then I understand. I would like for you to help me, but you may have more important cases to help with. Thanks.

    Do you have any important stuff on "infected" drive"?

    Not really. Just steam and some games for the most part. Nothing I need. Since I just fixed it about two weeks ago, the last time I used it was over a year ago. It was out of service for over a year.

    I suggest you simply format it.

    How many gigs would a backup of Windows 7 take up? I could put that on external memory of some sort and load it on the formatted hard drive. Would that work?
