My PC wasnt updated since June 2002. 3-4 months back the
system started showing problems when connect to internet.
It use to give me " ERROR to REFERENCE MEMORY" afetr a few
minutes once connect to internet..therafter System wont
disconnect from the net unless and untill shutdown.. Also
once system give the reference memory error message , no
other application would run on the computer saying "
Cannot open due to low memory". After a while i came to
know about the blaster worm. I updated my Norton anti-
virus ,,and immediately found WELSCHIA worm on my computer.
As per the information on the Net..I deleted DLLHOST.exe
and SVCHOST.exe from wins folder under system32 folder.
Also found MSBLAST.exe in the system and deleted it. Also
deleted 2 Rpcpatch folders in the System registry.

Then i tried to download the SP3 pack tp update the system
so as to download the DCOM security patch. After
downloading the pack when the pack was tryin to install,
System gave a " SYSTEM ERROR WHILE INSTALING THE PACK". I
shut the computer after waiting a while.

Now whenever i start my computer i get error message for
OFFICE setup. asking me to run the installation from the
location it is downloaded.  MSWord,  EXCEL
POWERpoint ...none of the application run on the computer
and asks to insert a windows 2000 pro cd..

Plz require guidance to this issue of office 2000 and also
to install the SP3 and DCOM security pack to prevent any
other system problems
