 Maybe try this Hard drive monitoring software and see what that tells you. The personal version should be free.

 What you should be looking at is the TEC,  " Threshold exceeded Condition" , it says n/a , Now I'm not sure if that means the smart settings weren't turned on in the bios when the system was setup, or that the hdd is ok for now. Maybe do some reading on the site to decipher the results.

Also, download and install Trend Micro HijackThis v2.0.2.

Then, click "Scan" and look for code 04 - HKLM\.. \Run: [pcoff.bat] C:\windows\

or something like that. then mark the corresponding box then click "Fix checked". Be very extra careful not to put a mark on other boxes.

hope it will help  smiley

you might still have some trojans which is not detected by your antivirus software. try the bitdefender online scan at http://www.bitdefender.com/scan8/ie.html

I have used the AVG antivirus home edition before and there were plenty of viruses and malicious files which was not detected.

If you're going to use the online scan of bitdefender, make sure to make the window smaller as possible and move it out of the way of your working area because once the scan starts, you won't be able to move the window unless you abort the scanning or until the end of scan.

How to Remove password_viewer.exe Virus

The "password_viewer.exe" virus executes during startup and cannot be easily disabled from the task manager. It shuts down your computer thru a batch file named "pc-off.bat". Surprisingly, this virus cannot be removed by known anti-malware programs but can be easily removed if done carefully on a manual way.

Here's how:

1. Turn off 'System Restore'.

Right click 'My Computer', click 'Properties', click the 'System Restore' tab, mark/check "Turn off System Restore on all drives", click Ok.

2. Restart computer in "Safe Mode" (press F2 or equivalent before the Windows bootup screen appears).

3. Now go to 'My Computer'. At the Menu bar click 'Tools', click 'Folder Options', click the 'View' tab. Scroll down and mark "Show hidden files and folders", uncheck both "Hide extensions for known file types" and "Hide protected operating system files", if a prompt appears click 'Yes', and then click 'Apply' and 'Ok' to close.

4. Open your system drive (usually drive C:), open 'Windows', scroll down, look for and delete the following files:

password_viewer.exe
pc-off.bat

- if a prompt appears each instance, click "Delete All".

5. Click the 'Back' button then go back to 'Tools', click 'Folder Options', click the 'View' tab. Scroll down and mark "Do not show hidden files and folders", check both "Hide extensions for known file types" and "Hide protected operating system files" and then click 'Apply' and 'Ok' to close.

6. Restart your computer to normal mode and turn on System Restore back by right clicking 'My Computer', click 'Properties', click the 'System Restore' tab, unmark/uncheck "Turn off System Restore on all drives", click ok.

You can check if the virus is still there by opening the Task Manager/Processes then look for password_viewer.exe. If its not there, you just had a successful virus removal. To test to make sure your computer doesn't shutdown when executing the Command Prompt, go to Start/Run and type cmd.

Good luck!

hey guys thanks a lot for your response, but here' s the actions what i did to remove this kind of virus hopefully it helps to the other's with the same problem to their pc.

how to remove bar311.exe Pc shutdown virus

This is the symptom of a computer having bar311.exe virus A.K.A. winzip123. The virus comprises bar311.exe, password_viewer.exe, photos.zip.exe and pc-off.bat.

When you boot your Windows XP in Safe Mode the message appears: Thank You!!!
Password:Winzip123

The pc-off.bat contains the syntax like this"C:/path/shutdown -s -f -t 2 -c" which automatically shutdown your computer when you run the cmd.exe. So heres the solution to this problem… just follow these simple steps that im goin to discuss….

Manual removal:

1. upon start up…. after os loading… go to task manager by pressing CTRL+ALT+DEL then kill (end process) password_viewer.exe or bar311.exe or photos.zip.exe…

2. EDIT the following registry entries thru regedit at start/run

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"Userinit"="userinit.exe,bar311.exe" —> remove ", bar311.exe" only… leave userinit.exe because this is used by Windows when you log-in…

[HKEY_CURRENT_USER\Software\Microsoft\Windows\
CurrentVersion\Explorer\Advanced]
"Hidden"=dword:00000001
"HideFileExt"=dword:00000000
"ShowSuperHidden"=dword:00000001

[HKEY_CURRENT_USER\Software\Microsoft\Command Processor]
"autorun"="c:\Windows\pc-off.bat" –> remove "c:\Windows\pc-off.bat" or delete the autorun key.

3. go to your thumb drive, please use the folders view in the explorer and use the navigation panel on the left side when accessing the drives to avoid triggering the autorun… then delete autorun.inf and password_viewer.exe or bar311.exe

4. open notepad then type what is shown below as is…

@echo off
del /a /f c:\Windows\bar311.exe
del /a /f c:\Windows\password_viewer.exe
del /a /f c:\Windows\photos.zip.exe
del /a /f c:\Windows\pc-off.bat
pause

then save this as remove.bat then click to run…. it will remove this annoying types of PC shut-off thing of virus… ;)
 
and also thanks to peepz... he is the man who responsible for making me free from this virus..
