Ok so like ur computer is screwed.
GET FIREFOX!
Next, you need to download, install and update 2 spyware removal programs... one is called
ad-aware and the other is called
Spybot.
THESE ARE FREE and I find that, when using one after the other, they clear 99% of all crap that manages to get onto your computer.
I would guess the "update" you downloaded was not a windows update at all and was in fact spyware.
When these 2 programs are installed, your best bet is to boot into safe mode and run them then, BUT ONLY AFTER YOU HAVE UPDATED THE DEFINITIONS FOR BOTH PROGRAMS! You must do this or it will not find everything.
Next, after this, if you are still having problems, then you need to check your startup sequence to make sure that you have nothing in there running that shouldnt be. to do this, go Start -> Run -> type "msconfig"
A window will pop up, click the selective startup button then click on the startup tab (at the top right). In here is a list of all programs that start when windows boots... A tick next to it means that it runs on startup. Look at each entry (expanding the "command" bit by dragging it so you can see exactly which file is being executed) and if it is not a program you want running on startup, or you do not know what it is, or if it looks suspicious in any way, untick it. If it turns out that you do want/need this program running on startup, you can re-enable it by following this same process in reverse.
When you reboot after doing this, you will get a message window saying something about the windows configuration utility being used to modify startup... simply tick the box saying "do not notify me of this again and do not run the utility when windows starts" and press ok.
You should find it loads quicker. Any problems, let me know
