Find and Delete a Virus using cmd..!!

This is old but gold for people who don't have much RAM to install an antivirus on their PC..
So here Am gonna tell you how to detect and delete a virus which has infested your PC..

Do the following steps..:-
->Press win+R to open RUN dialog box
->type CMD to open Command Prompt
A black screen like this will open up

Now, Microsoft Command Prompt "attrib" is a very useful tool to check if your hard drives even your flashdisks have been infected by a virus.

You will know if a Malware is inside your hard drive just by looking at the attributes of each files and the file that has the attributes of +s +h +r

The function of attrib is to set and remove file attributes (+r = read-only, archive, +s = system and +h = hidden).

To use attrib

1. Go to the root directory first by typing cd\(because this is always the target of Malware / Virus)
2. Type attrib and press Enter key

In this example, I have two files that are considered as malware.

Note that there are two files which I outlined in red (SilentSoftech.exe and autorun.inf). Since you cannot see this file nor delete it (because the attributes that was set on these files are +s +h +r and I have already mentioned what the stand for

Now we need to set the attributes of autorun.inf to -s -h -r (so that we can manually delete it)

1. Type attrib -s -h -r autorun.inf ( be sure to include -s -h -r because you cannot change the attributes using only -s or -h or -r alone)
2. Type attrib again to check if your changes have been commited
3. If the autorun.inf file has no more attributes, you can now delete it by typing del autorun.inf
4. Since SilentSoftech.exe is a malware you can remove its attributes by doing step 1 and step 3(just change the filename) ex. attrib -s -h -r silentsoftech.exe)

Image

There you have it!!!!

NOTE : when autorun.inf keeps coming back even if you already deleted it, be sure to check your Task Manager by pressing CTRL + ALT + DELETE ( a virus is still running as a process thats why you cannot delete it. KILL the process first by
selecting it and clicking End Process.

Thank you

by
ROSHAN


There are three ways to delete ,undeletable files and folders in your system.But in here I'll show you the most easiest two ways for do this.

This is the first method that I'm going to show you if you can't continue with this or if this isn't work you can try other method too.

* First Open a Command Prompt window and leave it open.
* Close all other open programs.
* Then Click Start, Run and enter TASKMGR.EXE
* In task manager Go to the Processes tab and End Process on Explorer.exe.
* Leave Task Manager open.
* Then Go back to the Command Prompt window and change to the directory to the undeletable file is located in.
* At the command prompt type DEL where is the file you wish to delete.
* Go back to Task Manager, click File, New Task and enter EXPLORER.EXE to restart the GUI shell.

Close Task Manager.


Also you can use the second method that I'm going to show inhere

* First create Notepad file.
* Rename it with your undeletable file name extension

ex: Think that you can't delete file with .EXE extension.So you need to change your notepad name to text.EXE like that.

* Now open it using notepad you can use open with option in your right click menu
* Click File and then Save As
* locate the folder where your undeletable file is
* Choose All files from the file type box
* click once on the file u wanna delete
* It should ask u to overwrite the existing file, choose yes and u can delete it as normal

THANKS FOR YOUR TIME................. ROSHAN

As we know by installing OS regularly we lost many of our important data and it's very time consuming.So how do we fix our corrupted data without installing our operating system. I found this method accidentally but this is a nice way to achieve our target. So I decided to post this in here for peoples who worry about their computer corrupted Files.

To continue with this tutorial to fix your system you need to have a Windows XP cd.If you have your exiting operating system installed CD I recommend to use it.

K lets begin with our tutorial,
First Put your XP CD into the CD-Rom drive
Then go to Start
Run
and type ’sfc /scannow’( It should be sfc /scannow without the ' ' )

This should fix your corrupted files in XP.It should load all files from cd to your windows folder. Actually this procedure does is a simple copy paste of the original file from cd to its respective location in your system.

Their is other way to fix this corrupted files in your system using your windows xp cd. It little bit alternate from our first method.

First Boot your computer using windows XP cd
Then ignore the first repair option you get "by pressing R"
Then move further as you do to install xp again.
When it shows you that Windows XP is already installed,
Then select it & there you will have repair option. So just repair it, this won’t affect any of your installed softwares so you don't need to worry about your installations.

You are done!

NOTE: You may lose the updated files that is done from windows update by going through this process, so you may have to update again to get those files.


thanks for your time..
