How to remove computer virus without installing antivirus?

Beginning Of Tutorial :

Start >> Run >> Type Cmd

In Each Drive Type Attrib /S /D It Will Display The List Of All Files In That Drive Along With Folders.Concentrate On Files Having SHR Attribute.Normally Virus Files Have Two Characteristics:

1. SHR Attribute

2. Queer Name Like Amvo.Exe,R6r.Exe,Auto-run.Inf Etc.

Note: Some System Files Also Have This Attribute Like MSDOS.SYS,IO.SYS Etc So Before Deleting Goggling About That File Will Help.

To Delete These Files Type C:\>Del /F /S /A  (File name With Extension)

To View The Content Of Files With .Inf,.Vbs,.C Etc I.E Files Which R Not Batch Files Or Executable.Goto Explorer N Then Goto The Required Drive Or Folder N Type The File name With Extension It Will Open Up In Notepad.

There Is Another Method Also.Goto The Required Location N Type Attrib -S -H -R File name. Then Use Gui To See That Hidden File. If It Is Not N Exe Or .Bat Or Then Open It With Notepad.Here You Will Get Some Information Like A File Name Or A Registry Key Which The Virus Affects Or A Start up Item Or Process.Change This Or Unchecked The Start up.

If File Is Not Deleted Like It Says Access Denied It Means It Already Used By Some Process.Open Task Manager N Find A Process Of The Same Name Or Some Process Which Is Not A Valid Windows Process(Better Google) N End That Process.

     If Not Found Open Msconfig Goto Statrup Tab N Look At If A Startup Items Seems Queer(U Will Have This Feeling If U R N Experienced Windows User Otherwise All the Startup Items May Seem Queer.)Uncheck That.U May Also Learn About Da Startup Item By Goggling.After Unchecking Restart The Computer Then Restart The Computer.

     This Method Is Effective In Removing Some Spywares Or Some Small But Annoying Viruses Like Mask rider Etc. Which R Sometimes Not Detected By Antivirus Software.
