XP Crashed. Cannot Re-Install. Pls Help!

Norton Anti Virus is possibly the only programme that will be successful in removing the virus.
Unfortunately XP is not supported by a lot of manufacturers any more but as you have SP3 you could be lucky when downloading updated drivers from the manufacturers web site.
Run avti virus first and then CHKDSK/F to attempt to repair the errors left by the virus.
Hope this helps.

Is it not starting at all or if it stat then to what step.Please tell so that we can give you the best solution we have

There are several options, both free and paid, to help you resolve this and protect your system from future attacks. While the paid options have more bells and whistles, the free systems are adequate for most users.

One of the top free options is Microsoft Security Essentials. Here's the download link: http://www.microsoft.com/security_essentials/
After you download the file:

Double click the exe file to run it.
Follow the instructions given to you.
When installation has completed, the program will open, update virus definition and you can start a scan of your system. Follow the instructions given to remove any flagged files.

For virus/trojan/spyware problems I would recommend you to go here:

http://www.techsupportforum.com/

Security Center> Virus/Trojan/Spyware Help> click the red "First Steps"

Follow there instructions. It will take sometime to fix, but they have Pro's who help for free.

1. Go to C:\WINDOWS\system32 and find
cmd.exe
Double click it. Does the window open? If not go to

Scroll down to "Line 228" on the right hand side, you will find Restore CMD.EXE click it.
Download to desktop then install.

yes, you need to install a special, Aspire One version of XP. This is a driver issue generally. You must either use the install DVD from Acer or get a specially made version with all necessary drivers built in. Format the Drive and reinstall windows. from that media.

Check in your bios if it sees your HDD in there, typically it is F1, F2 or DEL key while posting.
Is the laptop running an OS?

When you select the driver from the Acer WEB site, make sure you select your model laptop and the XP version of the driver.
The latest service pack for XP is SP3, I suggest you install it, try and get a copy of SP3 on CD because it is approx 350Mb in size and would take a long time to download.

first install xp2 then install xp3

i think there was one more virus called smss.exe with those 1 s in your system have a check ...
i think now also smss.exe file is attacked by virus in your system ...
those are trojan viruses ....
if you delete those ones also it will not go .... it will just multiply ...
if you insert pen drive in to pc then that virus will get attacked to your pen drive too ...

download some good trojan remover and then remove all viruses ...

some operating system files have got corrupted just reinstall the windows XP ...
make reinstall after removing virus only ...
or if you have the linux live cd then boot from that cd then delete those files and then reinstall XP ..

you cant install the office update from microsoft site because the microsoft office & windows you are using is not the genuine version so microsoft allows to download and apply the updates for the genuine users ....
download some good antivirus like kasperky,norton,mcaffe and install it
