I have a problem with computer security.

Original title: my computer is vulnerable, even with antivirus, anti-spyware and malware remover. Help, please!

I lent my laptop to a handful of individuals. (Very unwise, in hindsight). I am now worried that they could write down my serial number, product key, and any other way to 'monitor' my laptop. I understand that legitimate hardware like curries saves a copy of this information, as well as my biographical details but I like to keep my privacy when using my PC. Is it possible for an individual to TI to 'monitor' my PC, even though my IP address has changed?

Changing the IP address of your PC has no effect. It is a private address which is not visible on the outside.

You can change or hide your public IP address. It is assigned to you by your ISP and it is visible in each EMail that you send (if you use a local program to e-mail such as Outlook).
If you are worried that your friends may have installed some spying software then you should use system restore to set Windows to a point before you gave the laptop.
You must also make sure that the Windows Firewall is enabled and that you have a router between your computer and your Internet modem. If your private IP address is something like 192.168.xxx.yyy or 10.0.xxx.yyy, then you don't have a router.

  • I have a problem with the security being off center.

    Hello world. I'm trying to solve the problems on a laptop of series of 15NB57 Phillips, under Vista Home Premium, 32-bit + SP2.

    1 "the Security Center is disabled. After clicking the box "Turn on Now", the error message reads:-"the Security Center

    cannot be started ".

    After visiting the Microsoft Forum, in which relates to this specific issue, after you follow the instructions for 'Services', navigated to the folder 'Security Centre', as shown, & there is NO!

    "Security Center" can be installed on the computer 'Services', without that there is a backup drive, or a system image

    to fall back on, because the computer is old for a few years now, but still in good working condition? And, IF it can be done, how?

    Two software I have for protection that are on the computer are:-Microsoft Essentials, & Spybot S & D. I'd really like to

    you want to be able to put a real anti-virus/anti-spy on software.

    2. in the section 'Firewall' of the program, a command prompt says "Windows Firewall is not using the recommended

    To protect your computer, the settings ".  Along the coast, which is one is an another prompt 'Parameters of update now'.  After clicking

    "Update settings now", the error message reads:-"Windows Firewall was impossible to make the requested updates.

    And finally, always in the firewall section, the two features on the left hand...

    ... "Turn Windows Firewall On or Off" & "Allow A program Through Windows Firewall" on the TWO actions, the error message reads:-"due to a problem not identified, Windows cannot display Windows Firewall settings.

    I think the problems are especially linked, & these are produce because the "Security Center" in the section of the program Services does not exist. It could a virus of one form or another has deleted it.

    I am familiar with computers to a certain extent, but not when it comes to dive deeply into the program. With 'step by step' instructions when it comes to bios & register (I was at a time when looking for something that I had to look for), should be no problem.

    Any help, advice or assistance that can be offered, would be welcome, and appreciated.

    Thank you, in advance for your help.

    Yours Sincerely

  • I have a problem with a missing on the computer user account.

    Original title: problem getting back to the original account admin user

    Since the computer was new, I didn't have that one user account and didn't need a user to logon screen, when it opened to that and the only active user account. Fast forward 6 months that I had a problem with a windows installation file deleted and in order to get a program running I had to add a user account for the new installation of the user files. That part worked, but when I disconnected and tried to return to my original owner account there was only the new account on the logon screen my original account wasn't there. My files for this user account are still there in C: User but I can't find a way to get there.

    Googleing this problem I saw things about problems with the accounts being listed as AccueilCompte, or administrator, but it did get me anywhere, the only difference I've seen after going through all that I saw in Win7 Home Premium, which had to do with user accounts, it is that my original account was registered in a field as 'owner '. I don't know if it's part of the problem or not. How can I return to my original account and why isn't she appear on the opening screen of session or user accounts?

  • I have a problem with my computer

    I have a problem with my computer, I turned on my computer the next day and all the wat I could see was a new office with my files and missing files, but the hard drrive indicates that there are more files on the hard drive.please what I need to do? I have also to see the all the hidden folders, but always impossible to find out what anyone on the computer.

    It is a symptom of a corrupt user profile.  When Windows detects a corrupted profile, he creates a new temporary profile and continues to log.  Whatever you do, do not save critical files under this new profile.  Recovery is fairly simple and involves the creation of a new user and moving files over to the new user.  Moreover, sometimes a 'chkdsk' or 'System Restore' operation will restore the original profile.  The following articles describe how to recover from a corrupted profile.  Choose the one that suits you best.

  • "Windows services Centre" call by saying that I have a problem with my internal security system

    Hello

    I received a phone call from 'Windows Service Centre', James Henderson, employee of 406-235-1159, phone number #7098 (Yes, that's an indication 406 and 416 - which is one of the reasons why I'm suspicious), but gave a speech in Mississauga (Ontario), saying that I have a problem with my internal security system and even if www.ammyy.com I need to talk to the technician to solve this problem. I do not trust him and hang up, but called the number, responded to the same person (as he had an Indian accent with a lisp in addition to this) and he said that Joseph and not James!
    Scam or what? Thank you

    It is a scam! Who is becoming extremely common and was even on the news in some places. As long as you don't give them any personal information, you should be fine. Should they call once again, simply hang up.

    Original title: scams?

    I continue to receive calls from numbers not available with an Indian accent saying that they are from the Technical Department of windows and I have a problem with my computer. Normally, I just say that I don't have and hung up. Today, I took a little further and he said that they discovered that I had loads of malware/viruses etc and that they could identify with them. I was obviously very suspicious because he seemed to have my correct Windows ID number and with care on 'Run' he told me to type things like cmd eventviewer and inf where he referred to a file 1394.pnf. I stopped while he asked remotely to access my computer. However, I got a phone number 01916450337 and his P786000 id I noticed that many people are posting on your forum-is this another one of those scams?

    Continue to put the phone down. They are all crooks.

    They get you to open Event Viewer, because there are words such as 'critical' and 'error' along the this.
