Title: Definition Update for Windows Defender causing problems?
Post by: LizzieW on Sunday 28 October 12 12:11 GMT (UK)
I use Mozilla Firefox and had 2 updates yesterday one for Mozilla and the other one for Windows.  The Windows update is "Definition Update for Windows Defender - KB915597 (Definition 1.139.634.0)

I updated both Firefox and Windows yesterday at which point I could no longer get on to the internet - although I could send and receive e-mails, I use Mozilla Thunderbird.  I tried again today, thinking that turning the laptop on and off would solve the problem.  It didn't so I did a system restore to yesterday morning.  All worked OK following that, then Firefox gave me an update to instal.  I installed that and all was still OK.  Then Windows came back at me telling me there was an important update I needed to install to revise the definition files used to detect spyware and other potentially unwanted software.  I decided to update Windows and then, of course, I couldn't get on to the internet again.  So once again I did a system restore to yesterday morning and everything is OK again.

Has anyone else had any problem with this Windows update?

ps.  The weird thing is that even now, the little icon on the laptop telling me whether the laptop is connected to the internet or not has a red cross on it, implying that I'm not connected, however, when I click on it to connect to a network, it comes up showing I'm connected - as indeed I am or I couldn't send this message to Rootschat.

Thank you for that Stan, I'll turn Windows defender off as I already have Zone Alarm installed.

I'm now not sure the problem is Windows.  I had another update from Mozilla to update Firefox 16.02.  As my husband also uses Mozilla Firefox on his PC (and Virginmedia as our internet supplier - if that's the correct word) I checked if he had Mozilla 16.02 downloaded.  He had, he updated yesterday.  So I thought it would be OK to download Mozilla 16.02.  Guess what, I lost access to the internet again so I had to do another system restore.

I don't know why Mozilla Firefox's update would be a problem if it is OK on my husband's PC.

LizzieW - I'm no techy, but aware they like to know what version of Windows you're using. Is that the same as your husband's?

I'm using XP & Firefox 16.0.2 with no problems - I don't use Defender.

Of course, maybe that's the problem.  OH uses Windows 7, I use Windows Vista.

Perhaps I should update to Windows 7.

Got to leave here for the rest of today, we have builders in and they start a new phase of the work tomorrow, so I'm supposed to be helping OH move things around. ::)

Thank you for you help.

I don't use Windows defender but use Firefox, along with AVG, bought version, and Virgin media cable broadband. I am having trouble with performing backups, Windows backup has just completely given up, I also have Western Digital which supposedly does a continuous backup but now can't access it to prove it is happening. I wonder if there is a conflict here? Also using Windows 7.

I'm a bit loathe to update Firefox again, I've got rid of Windows defender (well disabled it) and everything seems to be OK so far today - apart from when the builders kept turning the electricity off when taking out the kitchen.  They said that as they're not "sparkies" they weren't happy just turning off the relevent switch on the fuse box, so kept turning everything off!

I'm using Firefox ver 16.0.1 and it is when I download ver 16.0.2 that I seem to have the problem.

Something I was wondering about since you stated problems with firefox, what differences are there between 16.0.1 and 16.0.2?
Anybody care to comment on this?

Lizzie, subject to others reading this, why not uninstall firefox ver 16.0.1 then download the latest version (16.0.2).
Maybe there is something in your current version that computer doesn't  like.

Firefox 16.0.2 downloaded even though I'd refused the request.  According to posts on Mozilla Firefox, when there is an update, Mozilla automatically downloads it to your computer but leaves it in the background, if you've asked to be notified about updates.  Even if you refuse the update, unless you remember to keep refusing it every day, after 24 hours of the update being in the background it will automatically update.


This was on a message board over a year ago and later messages say that Mozilla made the change in June.

Quote
Mozilla is changing the way Firefox handles updates. Mozilla has announced it will take yet another page from Google Chrome’s playbook and move automatic updates to the background where they will happen silently, without the need for user input. Of course that also means Firefox updates will happen without user consent, something Mozilla avoided in the past.

So you can refuse a request for an update, but after 24 hours it updates anyway.

LizzieW - I remember seeing that at the time, but thankfully it doesn't seem to apply in my case. I much prefer to do updates at a time of my choosing.

I quite often get the pop-up telling me a new version is out & ignore it for a few days in case I come across too much negative feedback - keep getting the pop-ups but no auto-install.

Using XP in Firefox under Tools > Options > Advanced
Second option selected - "Check for updates, but let me choose whether to install them"

Assuming all bookmarks in your ver 16.0.1 have been noted, uninstall firefox then reinstall new 16.0.2.
This should verify that (if now working correctly) problem was with 16.0.1.

I've got 16.0.2 now, it updated itself this afternoon.  My newer bookmarks are all in RoboForm so, fortunately, they are not affected.
