|"normal https start has changed into a red |
https which is crossed out, while next to it there
is a red skull with crossed bones underneath it. I am using Google chrome as the browser."
But then you say
"All my browsers (Firefox, Cnrome, Safari) run OK on my
machine, except IE8"
Now I'm confused.
Now what you can do with the IE8 is uninstall it and then SET your security updates to notify you and NOT install them.
Now you have the choice of rejecting IE8 if it tries to install again.
When you see the yellow shield on your taskbar, right click on it and choose 'Custom' installation. If IE8 is listed, uncheck it and then put a check mark in again to stop it from showing.
After that you can set the updates to automatic.
The next thing you may want to try is combofix:
Follow the tutorial on that page and you should be fine.
