T - bird very slow, freezes frequently. Cause: McAfee analysis in real time

Earlier today, T-bird was ok but would not send (I could send no problem my phone and my webmail, so I know that the problem was with the T-bird, or its interface with my server, but not with the server itself). I restarted my computer a couple of times and downloaded all the updates my system suggested and was able to send e-mail from T-bird, though only after several attempts. But now, the T-bird works very slowly and keeps freezing, with or without message "not responding". I'm trying to delete messages from delay to see if this is the problem, but even this is slow. Any suggestions? Y at - it an upgrade that I missed or something? Thank you. MaxineKL

  • Computer is very slow and IE does not work all the time.

    I bought a computer from my old employeer.  He is doing all sorts of things, or should I say not to do all sorts of things.  It is very slow and IE does not work all the time.  They have questions arise and ask if the administrator oks things and other things like that.  It came with any disks.  I would like to wipe, clean and load a new disc, but I don't know where to find the disc or if I can do it.   Can someone please?

    Hello

    Proceed as follows to contribute to these two questions. You can probably buy the disks of Vista machine to system or get
    the former employer to do it for you if necessary.

    Try these and it can also be a good idea to update your main drivers later. The General corruption can also play a
    role in this issue. And even the TCP/IP stack might need to be refreshed.

    What antivirus/antispyware/security products do you have on the machine? Be one you ALREADY had on this
    machine, including those you have uninstalled (they leave leftovers behind which can cause strange problems).

    If no joy there's something blocking perhaps.

    Start - All Programs - Accessories - System Tools - IE with no Addons - what works best?

    IE - Tools - Internet Options - Advanced - tab click on restore, and then click Reset - apply / OK

    IE - Tools - Internet Options - Security tab - click on reset all default areas - apply / OK

    Close and restart IE or IE with no addons

    not better?

    IE - tools - manage Addons (for sure disable SSV2 if it is there, it is no longer necessary but Java always install
    "(and it causes problems - you never update Java to go back in and turn it off again)." Search for other possible problems.

    Windows Defender - tools - software explore - look for problems with programs that do not look right. Permit
    are usually OK and "unauthorized" are not always bad. If in doubt about a program to ask about it here.

    Could be that a BHO - BHOremover - free - standalone program, needs no installation, download and run - not all
    are bad, but some can cause your question (toolbars are BHO).

  • Very slow / freeze while working with photos in Photoshop Elements and Canon DPP

    Suddenly my Windows XP has become very slow or crashes when working with photos.  I have Canon DPP and Photoshop Elements installed, and in the two following occurs: I can edit a photo without any problem but when I try to work with a second picture the system slows down / freezes.  It unlocks after a minute or two each time.  I tried cleaners registry check disk, Disk Defragmenter, virus, etc. etc. scans and no problems.  All other works very well and this problem started just out of nowhere.  Any suggestions or ideas will be greatly appreciated.

    Thanks John.  How do I disconnect from the internet?  I have a cable modem.

    ====================================
    I also have a cable modem and it has a button on top
    who's going to turn off/turn on the connection.

    If your modem does not have the button... you can
    Click on the "connecting to LAN" connection in the notification
    area of your taskbar and select Disable.

    If you go to... Control Panel / network connections you
    right click on the connection to the Local network and send a shortcut
    on your desktop. So, it is more convenient to right click...
    enable / disable...

    So, what operating system Mac are you on? You are not running an iMac on iOS.

    The Apple store actually erase your entire hard drive or they just install the OS on top of what you have?

    If you downloaded from any type of torrent/pirate bay Web site, there are some that will include a few unwanted songs (like bloatware/adware/malware) with their free software, especially if this software costs money elsewhere - for example, you might have installed something that will not be fixed by installation of operating system unless all of the hard disk will be deleted first. You can view the results after you run this small diagnostic tool of one of our employees of Developer:

    Please download and run a report of EtreCheck and then copy and paste the results into your answer.

    That should reveal the reason why your Mac is slowing down.

    Otherwise, it's just a guessing game.

    Personal data is shared in the report

    One thing you can try since it is slow to start. Open System Preferences > users and groups > login items. Delete a connection point at the time, and then restart your Mac to test.

  • TB, slow and not meet with 'The Script is not responding' mailWindow.js CAUSE: McAfee (new)

    I have been using TB and its predecessor Eudora for years without any problem. These last few months I met it is very slow and usually "does not" clicking on something before the end of the thought. At this point I sometimes get an error message "chrome://messenger/content/mailWindow.js:180", saying that the script has stopped working. I click on continue and it resumes.

    After reading the various posts on the topic several times I did 1) re-indexed 2) made a clean installation 3) disabled modules 4) run in safe mode. Nothing seems to improve things. typical symptoms are:
    A. Download emails seems to take normal time, but their display in the Inbox can take a minute or more (used to be instantaneous) by clicking in the intermediate product, the message "not responding".
    B. Sending messages seems normal
    C. selection of a mail in the Inbox, or try to move or delete one takes a minute or more. Click on in the meantime generates the message "not responding".
    D. generally every action with the mouse has this long accompanied "not responding".

    I use Windows Vista, McAfee is installed but disabled does not make a difference.

    Try resetting your device. This will not erase your data stored on that device.

    • Press and hold the sleep/wake button
    • Press and hold the Home button
    • Press and hold both buttons until the display turns off and on again with the Apple logo on the subject.

    Alternatively, you can go to settings - general - reset - Reset all settings

    If that doesn't work, restore your device to factory settings. Please note that this will delete the data on your device.

    Take a look this Apple Support article: use iTunes to restore the iPhone, iPad or iPod to factory settings - Apple Support.
