I'm having the problem where windows task manager disappears after about 2 seconds. When I hover over the green checked icon, it disappears there as well. Also, when i shut down the computer, it says something about closing hidden shell icon window. This problem started first and I'm not sure if it's a virus/worm etc or something wrong with my computer. Any help especially with the task manager would be really appreciated

Eliza, I suggest that you update your virus definitions and run a full virus scan. The link below may be of some help. Why does Task Manager disappear while opening?

I've updated my virus scanner which comes up clean, and i've got Spybot and Adaware, and I've deleted all the adware, this still hasn't fixed the problem
Eliza, Go to the link below and under the letter "T" scroll down to "Task Manager - Control/Alt/Delete - Doesn't work" where you may find a possible solution. Tufenuf
Thanks, I used the links you provided and eventually downloaded the online symantec virus scanner. This detected W32.Mydoom.BU@mm
I downloaded the automatic fix for this virus, but it said it could not detect the presence of this virus. So I'm really not sure how to get rid of it now
Eliza, Follow the W32.Mydoom.BU@mm Removal Instructions for Windows XP at the link below. It appears to be a brand new variant of the Mydoom virus. W32.Mydoom.BU@mm Removal Instructions

I tried this automatic removal tool and it says that it cannot detect the virus (after a symantec virus scanner already detected it). I tried to manually remove it, but once i opened the ETC file, there was no notepad file in hosts.
Eliza, Do you have an Antivirus Program installed on this computer? Did you turn off System Restore then restart your computer? After doing this run another virus scan. As far as the hosts file if you can't open it with Notepad try using Wordpad to open and edit it if necessary. The generic Windows XP hosts file (no extension) should be as shown between the lines below.

DO NOT Remove the 127.0.0.1 localhost entry

I did have Macfee Virus scan, but I first realised that I had a virus when I couldn't open this program. I did run the virus scan with system restore turned off, then restarted it, and it still did not detect the virus. Within the etc file, there are several smaller files, and i'm not sure which to use- there are hosts, lmhosts, networks, protocol and services
Eliza, The file you want to open with notepad or wordpad is the hosts file that has no extension. It should look exactly like the one I posted in my Response Number 7. Tufenuf
OK, here's my host file. # Copyright (c) 1993-1999 Microsoft Corp.

What should I do with this file? there doesn't seem to be anything different from what your no. 7 reply looked like?
Eliza, Your hosts file looks fine so leave it as is. I'm out of ideas to correct the Task Manager problem and maybe someone else will come along with a possible solution. Tufenuf
Thanks very much for all your help anyway, I really appreciate it.
