Kill unecessary processes
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
http://task-killer.smartcode.com/info.html
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.
Better than antivirus programmes

analysis of the viruses
viruses spread through
- webpages containing scripts.
- removable drives(CD-R,CD-RW,Floppy Drives,Flash Drives)
- downloaded softwares from unknown sites
Webpages contain javascripts,vbscripts which change the computer settings and run the virus programmes. But every time we come across a script page the browser(IE,opera,mozilla..) warns us. This scripts can be permanently made off in the browser settings.
Removable drives come with a autoplay/autorun option, that helps the virus writers. if u put a text file autorun.inf it will run the programme written on the file. when the user double clicks the drive(also possible in local drives ..C://) it runs specified programme(here it is virus). There are some scrpits which runs virus on right click on drive. The viruses once started
- Link themselves with the system files
- Sheduled to start every time a user log in.
- They a leave copies in system folders
- Change the system registry
- Change the folder option(Disable show hiden file,system file,file Extension name)(Nonrecoverable)
- Lock the Ctrl+Alt+Dlt option (Not in all viruses)
- Lock the taskmanager (Not in all)
- Lock the RegistryEdit (Not in all)
- Lock the Command Prompt (Not in all)
Softwares from some unknown sites contain hidden viruses. when the user double clicks on it uncopmress and then run the programmes including the virus. it does its work right but hiddenly it makes way for the virus.
Prevention
- Allow scripts from trusted sites
- Do'nt double click or rightclick on any drive (local/removable)
- disable windows scripthost(wscript.exe)(just replace with any .exe file with same name otherwise it will be reinstalled automatically)
- show hidden files,system files, file extension in folder option..
