Application Error, please help
Hi all,
I have a problem with my Inspiron notebook recently. Everytime I log on to the internet, a message will pop up saying
" Isass.exe application error. The instruction at "0x00900090" referenced memory at "0x00900090". The memory could not be read"
I have just updated my windows but the problem still occurs. If I click ok to terminate the program, my notebook will shut down in 60seconds.
Please help me, I am using XP Home edition.
Thank you so much.

sounds very much like you have the sasser worm.
you can get the sasser removal tool from http://securityresponse.symantec.com/avcenter/venc/data/w32.sasser.removal.tool.html
to temporarily stop windows from shutting down so you can apply the fix go start>run & type in shutdown -a then hit ok.

Hey, Sounds like it could be a lot of different things. Run a virus scan first. Next thing go into your diagnostic program. Reboot and hit f12. Select the diagnostic from the list. Check your ram, and most importantly check your harddrive. I've had similar problems that turned out to be bad sectors on the harddrive. If you do have bad sectors and it's under warranty call Dell, if not run SpinRite. I solved bad sector problems with SpinRite. Why can't you download the symantec tool? But firstly, why would you download the tool unless you know you have the virus? You need to use a current virus program to check for this first, before downloading any remover. You can always try an online virus scanner. Here's a good one http://housecall.trendmicro.com/housecall/start_corp.asp . Once you've done these two things then you have to move to other steps. It could be a virus, bad sector on your disk, ram, a bad program. But start with a thorough virus scan and diagnostic scan, but do the virus scan first. Cheers,
PD

Oops! Sorry, you sound like you have the Sasser virus. This is what MS recommends you do http://www.microsoft.com/security/incident/sasser.mspx . You might run that virus scanner I suggested in the last post in safe mode. Hit f8 while the machine is booting and pick safe mode with network support if you've got a network connection to the internet. You should also be able to run windows updater from safe mode, I think.
