SAVE PC FROM PENDRIVES
How to backup your important data when your pen drive is infected with a virus ?
a. Insert your pen drive into the usb port, if it detects your drive you will see it in my computer. b. Now don’t double click on your drive, rather open the pen drive contents by typing the drive letter. For Example: type g: and press enter if your pen drive is shown as new g drive under my computer. c. Copy your important files from your pen drive close the window and format your pen drive after then.
If you are still suspicious about the existence virus files on your pen drive, you can remove virus from your pen drive through command prompt by the method here.
One of the ways by which a virus can infect your PC is through USB/Pen drives. Common viruses such as ’Ravmon’ , ‘New Folder.exe’, ‘Orkut is banned’ etc are spreading through USB drives. 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 Whenever you plug a USB drive in your system, a window will appear .
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 pen drive. Check whether the following files are there or not • Autorun.inf • Ravmon.exe • New Folder.exe • svchost.exe • Heap41a • or any other exe file 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 an anti virus program 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

Trouble:
Some times PC is infected with w32.hitapop virus. It is basically a worm / virus also called hitapop virus/worm. It embeds itself with the userinit action at the startup of the computer and runs certain malicious code as soon as a user logs into the system. This causes downloading of virus like contents and damages to computer software. How to remove W32.Hitapop virus from your computer Trouble: PC is infected with w32.hitapop virus? It is basically a worm / virus also called hitapop virus/worm. It embeds itself with the userinit action at the startup of the computer and runs certain malicious code as soon as a user logs into the system. This causes downloading of virus like contents and damages to computer software.
This virus can be easily fixed up manually by following the steps mentioned below:
Fix: Let’s see how can we remove this software Follow the procedure below:
1. Go to Start > Run, type regedit in the in the Run dialogue box and press enter. This will open the registry editor. To be able to open registry editor you need to have administrator rights, if you don’t have administrator rights, see this post. Even then if the registry editor is not opening, see this post.
2. Once you have opened the Registry editor, navigate to the location HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
3. At this path there is a key called userinit. The key is usually set to a value which tells what is to be executed at every time a user logs in. If your computer is infected with some virus, then the value should be something like “Userinit” = “C:\WINDOWS\System32\userinit.exe,rundll32.exe %System%\winsys16_[RANDOM DIGITS].dll start” Note down the above [RANDOM DIGITS] on a piece of paper, we will use it in step 8 to remove virus files....
4. Change it to a value “Userinit” = “C:\WINDOWS\System32\userinit.exe“
5. Exit Registry editor.
6. Go to Start > Run , type cmd and press enter, this will open a command prompt window.
7. On command prompt, type ” attrib -s -r -h c:\windows\system32\winsys16_[RANDOM DIGITS].dll” and press enter. Note that this random number is the number you get in step 3 above.
8. Now type Type “Del c:\windows\system32\winsys16_[RANDOM DIGITS].dll” and press enter. This is also the same random number as in step 3.
Now close the command prompt, restart your computer. We hope this will help to fix the trouble

Trouble:
We have been getting lots of virus problems which infect computers through autorun.inf file as autoplay is enabled on the windows drive by default.
1. Open Start >> Run or press Window + r
2. Open registry by typing regedit.exe and press enter
3. Navigate to the following path: HKEY_CURRENT_USER\Software\ Microsoft\Windows\CurrentVersion\Policies\Explorer
4. Double-click the NoDriveAutorun registry key and type the value in Hexadecimal as FF ( or 255 in Decimal). Note: If their is no NoDriveAutorun registry key, just create it by right-clicking the right side area of the regedit window, then select New >> DWord Value >> type NoDriveAutorun and press enter.
5. Exit registry and restart your computer for changes to come into effect.
This is how you can disable autorun on all your drives and at least will prevent autorun activity of virus infected USB pendrives or CD’s and avoid infection through autorun.inf viruses.

Trouble:
As we all know the expected behaviour is that each drive opens in the same window until a user has explicitly set the option Open Each Folder In Its Own Window. under File menu >> Tools >> Folder Options in General.
Why It drive opens in new window?
It happens when a program or virus tries to edit the File Folder or Drive shell entries to add more context menu items and set them as default for double click action.
Lets see how we can fix this.
Fix:
First Method:
1. Open Start >> Run and type regsvr32 /i shell32.dll
2. press ok
3. You will see a message DllRegisterServer and DllInstall in shell32.dll succeeded

DRIVE OPENING PROBLEM..
Trouble:
Sometimes it happens in windows XP that you are not able to open drives on your hard disk.
When you double clicking on the drives icons or right click on the drive>>explore in My computer ,the drive does not open.
This problem is generally caused by most of the viruses which infect windows XP system. They block or restrict your access to any of the drives.
But don’t worry this is not a big trouble it can be fixed easily.
Fix:
Normally when a virus infects a windows system which causes a drive opening problem, it automatically creates a file named autorun.inf in the root directory of each drive.
This autorun.inf file is a read only ,hidden and a system file and the folder option is also disabled by the virus. This is deliberately done by the virus in order to protect itself. autorun.inf initiates all the activities that the virus performs when you try to open any drive.
You have to just delete this file and restart your system to correct this problem.
Follow the set of commands below to show and delete the autorun.inf
1. Open Start>>Run and type cmd and press enter. This will open a command prompt window. On this command prompt window type the following steps.
2. type cd\
3. type attrib -r -h -s autorun.inf
4. type del autorun.inf
5. now type d: and press enter for d: drive partition. Now repeat steps 3 and 4. Similarly repeat step 5 for all your hard disk partition.
Restart your system and your trouble will be fixed.
