Kill unecessary processes

In winXP there are some way with which u can check for any stray processes and kill them.

1. Right click on the taskbar, click on task manager....then click on processes tab..

if u hav no acess to it(damaged by virus) u can try task killer from the link below

2. Check for the processes. if it is not in the list below then check in google about it. just type the process name and search.

taskmgr from ur current user
alg from Local Services
hkmcd from ur current user
igfxtray from ur current user
spoolsv from ur current user

System from SYSTEM
MDM from SYSTEM
System Idle Process from system
SVCHOST (MULTIPLE) from NETWORK SERVICE AND SYSTEM
SERVICES from SYSTEM
LSASS from SYSTEM
SMSS from SYSTEM
CSRSS from system....and more 4/5 processes

but the viruses generaly run from the username-=ur current username(the login name)

they generaly copy the name of system processes.

so u should regularly check for suspicious procesess and kill delete them. and if u can then search whether it is generated by any other virus residing in ur harddisk.
