Only https links work. Never installed security software. Never messed with the settings of internet connection. Refreshed Firefox. No joy.

Firefox worked like a dream for as long as I got - until two days ago.
It suddenly stopped linking to http sites. Still works for https sites, however.
This problem does not exist in Safari (but I prefer Firefox!).

Some dig and can already tell you that:
(1) no additional security software have been installed.
(2) no changes were made to internet connection settings.
(3) connection Wifi is strong and fully functional (as it has always been)

I followed the procedure of "Refresh" recommended on this forum - still no luck.
I am the only person working on the two devices listed below.
They are not networked.
Only for personal use at home, or when they realize (the laptop).

iMac: 7.1 model
OS X (Snow Leopard) 10.6.8 (the Mac is too old to support higher versions)
Memory: 1 GB

Have the same problem on many newer MacBook Pro:
OS X (Mountain Lion) 10.7.5
Memory: 4 GB

Make a check of malware with several malware scanning of programs on the Windows computer.
Please scan with all programs, because each program detects a different malicious program.
All of these programs have free versions.

Make sure that you update each program to get the latest version of their databases before scanning.

Alternatively, you can write a check for an infection rootkit TDSSKiller.

    Hello again,

    Thought I would let you know that I've finally sorted this! :)

    In another forum I read a post from someone who had a similar problem and solved it by uninstalling the "failures" updated, restart the PC and then re-run the update. It worked! It had not occurred to me to try what I've assumed that 'impossible' meant that they had not installed at all, not that they didn't had simply not installed correctly and must have become corrupt.

    I hope this will help someone else who has the same problem, I've had!

    Best wishes

  • Impossible to install security software 1603,0, 0 x 000 errors

    For the last 3 weeks I tried to install Trend Micro Internet Security software. Initially the 1603 error is out of my attempt to upgrade my version 3.51 to the latest version 5. Software Trend Micro uninstalled my old version then threw a 1603 error when you try to install the latest version. I tried this site and had a broad Trend Micro remote support. The last attempt to remedy the situation failed after 2 1/2 hours of support away from the Hungary and about 5 trying to clean my registry windows and re install my deep security software. Their developers (Tren Micro) came to the conclusion that the fault lies with the installer of windows on my pc. Even if I ran sfc/scannow and no error was detected, I can't get any software security at all to install not only Trend Micro.

    As I mentioned briefly earlier that I did everything what to do in what concerns the cleanup of registry entries and temporary directories that is the first step to try to resolve these problems

    I need options. Windows reports under its security suite that Trend Micro is installed, but not in a format it recognizes. This is misleading and does not allow me to make one installs clean

    Any ideas?

    This is just to inform everyone that this problem has been resolved. Extended support Trend Micro resolved after suspending system restore facilities which I think affected the file access permissions. My security software is now installed, updated and working properly

  • Satellite P200-140: cannot install software on Vista with the administrator account

    Hello

    just bought a new P200-140 Sat with windows vista at home, but I cannot load the software on the computer.

    I'm in administrator mode and when I am trying to load the software I get an error message saying "can only load software as an administrator of disconnection and reconnection as Administrator", but the problem is that I am the administrator.
    can anyone help

    Hello

    Are you sure that the admin account has been activated and you are connected with the admin rights 1005?

    I asked because the administrator in Vista OS account is disabled by default.
    Why? Well, it's an idea to Microsoft ;) and I think that the user must often work with limited rights.
    But if you want to enable this account you can do the following:

    -Right-click on the computer
    -manage
    -users and groups
    -double click on administrator
    -Remove the brand to deactivate account

    After this procedure you can connect to the Vista operating system as an administrator.

    I hope that these tips will help you.

    Good luck

  • Windows installed the automatic windows update agent and I would appreciate help with the settings option in this newly installed agent update so no update never install or download unless I choose to do.

    Hello.

    I have windows vista 32 bit home edition.

    Today somehow automatically installed windows ' automatic update agent 747600226

    I always keep my settings to check the updates but let me choose whether to update or install.

    With this new "update automatic agent" which automatically installed on my system, I want to make sure I have place it properly so that it remains in the same way that I always have my settings but two settings (options), he checked, and are confusing for me to know what those checked settings will do.

    I would like to help you with these settings to make sure that the update is still as I want.

    Below chose correctly when the new program installed today.  That's how I still want the settings to be:

    Look for updates but let me choose whether to update or install

    Please let me know if I need to change all the options account required in addition to this update agent to ensure that only, I choose to update or install.

    There are four options and a box is in two and I don't know if I should remove the check marks or not.

    Here are the other four options that I need to know how to configure it so that only I have update/install.

    Once again, the download automatic microsoft today (update automatic agent 7.4.7600.226) without asking for my incentive preset automatic update options and that's what I'm trying to make sure is set correctly so that nothing installs or updates without asking me or let me do.

    Option 1: (this option is checked. If I leave it checked will be it install or warn me only?)

    Give me updates recommended in the way I receive important updates.

    Option 2: (this is not checked and am not worried about this one)

    Allow all users to use installed on this pc.

    Option 3:
    (this is checked and want to know if should uncheck; what I don't want is any what to auto install, but the wording of this option and option 1 are vague because of the "give me " so I don't know what it means or will do.)  If this box is left to it automatically update/install?)

    Give me updates for Microsoft products and looking for new optional microsoft software when I update windows

    Option #4 (this is not checked, and I am not concerned about this).

    See the notification me detailed when new microsoft software is available.

    Thank you very much for your help.

    Take care! :)

    Hello

    The Windows Update automatically updates the updater (himself), regardless of your settings.

    1. Yes it will alert you so you can update or install.

    2. check if you need more of yourself (other users) to be able to select and install the updates.

    3. it will let you know when they become available.

    4. just gives the news of additional details about some of the updates.

    Looks like you're ready for anything you like.

  • Portege A600 Webcam software crashes when changing the settings with the sound muted

    I have a problem with XP Toshiba factory build for Portege A600 and Portege R600.
    If you try to change the sound properties of the Webcam using the Camera Assistant Software with the sound muted, the camera wizard app will hang & Windows fails to shut down or even stop. The only way to stop is pressed the power button until the machine stops.

    So far, the only solution I can come to is to increase the volume to zero rather than using the mute box. The problem is if you forget and mute rather than turning down and then try to change the sound properties, its "game over." In addition, it is not really satisfactory because politics is to keep the machines muted until the sound is required.

    This does not happen with the Vista Build, build it only XP.

    My guess is that this will not happen on any machine using the Chicony Webcam & software with the Realtek HD audio but I have not tried on machines enough yet to be sure. So far, I've recreated on two A600s and a R600. The machines are not defective and you can create the problem, "straight out of the box. Just do the following:
    (1) use the provided Toshiba product recovery DVD for restore factory Toshiba Windows XP SP2 version
    (2) once you have done the whole stuff, mute
    (3) open the Camera Assistant Software application & to select Properties
    4) click the audio settings tab

    That of all, suspended. The Camera Assistant Software version is 1.7.209.0807L which seems to be the last being available for download on the websites of Toshiba.

    Someone has encountered this or have any suggestions?

    Hello

    I n t have a Portege but U400 with pre-installed and integrated webcam Win XP.
    I installed a clean Win XP and then upgraded the XP to the last State and installed all the drivers available from the Toshiba page and possible.

    I followed the steps in your message and I have to say that I didn t notice strange questions, software webcam still works correctly

    I put t know what could be the problem, but I recommend that you check the audio driver to update maybe you can use the Realtek page
    Also, check if the BIOS has been updated to the current state and if your Windows XP is up to date.
