Thankyou Fed for so much help, and no i dont have windows update in start menu , but i have windows updates enabled , its in the control panel ,in security settings.
Thankyou again.

[Fed]

Your Internet Explorer has an 'odd' version number have you ever had IE7 on that machine? It may be mis-reporting the number.

I see you haven't used the Spybot S&D realtime protection, any reason?

[Ivy]

 I dont know where to get Spybot S&D realtime protection from. I dont know about the number of IE ,could you please help me with this Fed, thankyou so much for so so much help already.
Thankyou.

[The Saviour]

You can get SpyBot Search and Destroy from here, Ivy:

Spybot Search and Destroy

To find out what version of IE you have...from IE's toolbar menu click Help/About Internet Explorer and copy the version number down.

-Steve

[Fed]

If you already have Spybot S&D then just open it up then change the 'Mode' at he top of the screen to 'Advanced', if you don't have Spybot S&D then get it from here.
Spybot S&D
Then we can go on from there.

I don't know about your IE6 Version number either, perhaps someone with IE7 can help with the Version Number.
I don't think it's anything to worry about at this stage.

You can check it in IE>Help>About Internet Explorer.

Edit: When I hit post and saw that you had posted Saviour I thought, "I'm not wasting my additional typing so I posted anyway. LOL!"

[Ivy]

Thankyou ,
Here is the IE version number:
Version-6.0.2900.2096
Cipher strength:128bit
Update version:;SP2;
Now im gonna try the Spybot real time protection.
Thankyou again.

[Ivy]

It has  the options to downdolad it from a number of locations , do i select just one location at random?

These are the options given.
Download Spybot-S&D [link]

Any choice should be fine.
This is common for popular DLoads as the huge amount of traffic can bog things down.
A mirror is simply another server who has volunteered to host the file for DLoad.

[Ivy]

Thankyou ,
I downloaded the file but at 21% it says download complete, and when i try to run it, my comp displays the message that the setup  files  are corrupted please obtain new copy of the program.


(Same thing happening on youtube , downloads only half of the video)

[Fed]

Spybot S&D

[Ivy]

Again the same message.
setup  files  are corrupted please obtain new copy of the program.
Im gonna cry. why is my computer so horribly against anything i wanna do!!!!!!!!

[Fed]

Clear your Temporary Internet Files, they can do some 'odd' things to downloads, don't ask me why.
IE>Tools>Internet Options>Delete Cookies, Delete Files, Clear History.

[Ivy]

I have set the settings of IE on default, and till now it is downloading , hope it survives till 100%, I have cleared all cookies, files, history, actually i ran ccleaner .
Im waiting,it seems to be working right now.

[patio]

What type of connection are we talking about ? ?

[Ivy]

OH NO!
I tried again ,at 82% it again stopped, and then again i tried downloading it and at 46% it again stopped.
pleeeeeeeeeeeease help me.
Could it be that comodo is doing somthing?

What type of connection are we talking about ? ?

Im sorry , im unable to understand this.
