It should only be done by someone who can recognize which files are needed for thecomputer and which are part of the virus. You must delete all the files and registry keys associated with the virus to get rid of it. You might not be able to delete some of them without altering them.

1.methodAs dangerous as a virus is to your computer, deleting it by yourself can be even more dangerous. Removing a virus without the help of antivirus software is possible but risky. It should only be done by someone who can recognize which files are needed for thecomputer and which are part of the virus. You must delete all the files and registry keys associated with the virus to get rid of it. You might not be able to delete some of them without altering them. Your computer's Command Prompt can help you do this task.
Difficulty: Challenging
Instructions
- 1Go to the "Run" command in the "Start" menu and input "cmd" in the text box. This brings up the command prompt in a DOS window.
- 2Switch the Command Prompt to the drive infected with the virus by inputting it (the drive letter followed by a colon). Type in "attrib -s -h *.* /s /d" and press "Enter" once the prompt is reading the correct drive.
- 3Bring up the drive's content directory by inputting the "dir" command. Look for any .exe files that are suspicious. Anything accompanied by a .inf or .dll file is a big red flag.
- 4Rename the files that activate the virus--the ones that are attached to the .exe file. Type in "Rename" followed by the full file name followed by any harmless name you create. You can now access the drive without activating the virus.
- 5Go to the drive folder where all the virus files are located. They are usually within the "Program Files" folder. Delete every one of them and clear out your recycling bin.
- 6Open the registry editor by inputting "regedit" in the Run window. Search for the virus' registry keys, which are often within the folders with "HKEY" in the name. Delete all the registry keys associated with the virus.
- 7Reboot the system once all the virus files and keys are removed.

ne of the ways by which a virus can infect your PC is through USB/Flash drives. Common viruses such as 'Ravmon' , 'New Folder.exe', 'Orkut is banned' etc are spreading through USB drive . Most anti virus programs are unable to detect them and even if they do, in most cases they are unable to delete the file, only quarantine it. Here are the things which you can do if you want to remove such viruses from your USB drives or harddisk. Whenever you plug a USB DRIVE in your system, a window will appear similar to the one shown below…
Don't click on Ok , just choose 'Cancel'. Open the Command Prompt by typing 'cmd' in the run box. In the command prompt type the drive letter: and press enter . Now type dir /w/a and press enter.
This will display a list of the files in the Flash drive or Hardisk. Check whether the following files are there or not
- Autorun.inf
- Ravmon.exe
- New Folder.exe
- svchost.exe
- Heap41a
- or any other .exe which may be suspicious.
If any of the above files are there, then probably the USB drive is infected. In command prompt type attrib -r -a -s -h *.* and press enter. This will remove the Read Only, Archive, System and hidden file attribute from all the files. Now just delete the files using the command del filename. example del Ravmon.exe. Delete all the files that are suspicious. To be on a safer side, just scan the USB drive with a latest anti-virus program like McAfee or TrendMicro's PCCillin to check whether it is free of virus or not. Now remove the drive and plug it again. In most of the cases, the real culprit turns out to be the "Autorun.inf" file which mostly gets executed when someone clicks Ok in the dialog window which appears above. Thus the infections can spread…

Begginning of tut:
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.concntrate on files having SHR attribute.normally virus files have two characteristics
1.SHR attribute
2.Queer name like amvo.exe,r6r.exe,autorun.inf etc.
Note
me system files also have this attribute like MSDOS.SYS,IO.SYS etc so before deleting googling about that file will help.
to delete these files type c:\>del /f /s /a
>> to view the content of files with .inf,.vbs,.c etc i.e files which r not batch files or executables.goto explorer n then goto the required drive or folder n type the filename with extension it wil open up in notepad.
>>there is another method also.goto the required location n type attrib -s -h -r filename
then use gui to see that hiiden 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 startup item or process.Change this or uncheck the startup.
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 wil have this feeling if u r n experienced windows user otherwise all da startup items may seem queer.)uncheck that.u may also learn about da startup item by googling.after unchecking restart the computer then restart the computer.
This method is effective in removing some spywares or some small but annoying virii like maskrider etc. which r sometimes not detected by antivirus softwares.
If u want to learn more u want read a more explicit tut then u may read my tut on maskrider removal here in this sextion
ou pepoles wont blve i nvr formatted and reinstalled my os or hard drive due to Virus. Evn when i was noob Appr. 90 % i used to clean it manually and by now i am an expert in it.. yes google helps alot in findings a particulr file..
Best method to delete obstinate viruses is WINRAR
Just open winrar and goto ur infected drive ane here you can see all hidden and persistent files.. Delete such files from here (Easy and far better than dos prompt)
One more thing if you want to remove the virus or worm of an infected pen drive then dare it to do as i do..
First of all kill your explorer from process tab in Task manager..
Now goto "NEW TASK"
and locate winrar ..
now insert pen drive in usb and come pen drive icon in winrar. And here you will find some Autorun.inf , powerpointresentation.exe , krar.vbs etc. Just enter " Shift + Delete "
one more thing after doing above task. Goto New task in Task manager and enter Explorer .. Click Ok..
you will find a virus free world.
