What is ransomware and how do I protect my PC from WannaCry?
My laptop has become poorly again (it had a CD drive replacement a few months back, which incidentally is still temperamental, not sure if that info will impact on the problem below??)
It is a Maxdata laptop running Windows Vista Home. It is due for a clean and defrag I know but I can't do this as it is currently not working at all!
Whenever I try to open anything, i.e. Internet explorer, itunes, Windows Help and Support, I get one of two error messages in the bottom right, either "Werfault.exe - the file or directory C:\Users\ myname>\AppData\Local\VirtualStore\Windows is corrupt and unreadable, please run chkdsk utility. Or the same message with Iedw.exe at beginning instead.
I couldn't get chkdsk to run first of all, but then managed it through command prompt, it ran on restarting and found nothing. On the advice of a friend I ran sfc/scannow and it said it had found some corrupt files but was unable to fix them and gave this C:\Windows\Logs\CBS\CBS.log which I can't do anything with, whatever I do says access denied. (I am the only user/administrator).
Can anyone help me? What/where might these corrupt files be and why? and what can I do?! (Is it anything to do with the fact that I haven't installed service pack yet that popped up in my windows updates yesterday?)
Just tried to open itunes again in vain hope it might have fixed itself, and got BSoD with something about a Bad page in a non paged area I think? Dear me. Would appreciate any suggestions very much. Many thanks.
With your problems I would be inclined to save every important file, document and photos etc., and use the restore disc that came with the laptop or which you created with the manufacturers burner. Failing that there must be a restore partition which you should be able to access by tapping a key such as F11 to gain access to this restore partition. Read the manual that came with the laptop.
MAKE SURE you backup everything personal as these will be wiped after a restore to factory settings.
Werfault.exe Iedw.exe are part of Vista error reporting.
As you have run chkdsk without problems I think you need to do either as rdave13 says a factory restore or a Vista repair:-
How you access the repair options will depend upon whether you have a Windows Vista installation disk or whether your operating system came pre-installed by your PC manufacturer.
Windows Installation Disk
With the Complete PC Restore Option you must have made a backup of your system, either on your hard drive or on a set of DVDs, in order to use this option. If you don't have a backup then don't use this option
1/ make sure your PC can boot directly from the Vista DVD. Obviously, most modern PCs can. With older machines you may need to check the PC's BIOS
2/ Start the PC
3/ Immediately insert the Windows Vista DVD into the DVD drive
4/ A Black screen will appear with the words 'Press any key to boot from CD or DVD'
5/ Press Any key to start the booting process
6/ A new screen will now appear with a progress bar. The legend say's 'Windows is loading files'
7/ After a few minutes the Microsoft copyright window ill appear and another small progress bar will be visible
8/ You will next see a Blue curtained screen
9/ After a short while the Language option screen will appear
10/ Select your language and keyboard language and the Click the Next button
11/ At the bottom left of the next screen - the Install screen, Click on the Repair Your Computer option
12/ The System recovery options will now search for your Windows Vista installation
13/ Once the Vista installation has been located, Highlight it and then Click the Next button
14/ You are now presented with the following set of recovery options
* Startup repair - This automatically fixes problems that are preventing Windows from starting
* System Restore - This will Restore Windows to an earlier point in time
* Windows Complete PC Restore - This will completely restore your entire PC - programs, system settings and files - from a back up that you have previously created (Available in Windows Vista Business, Enterprise and Ultimate editions only)
* Windows Memory Diagnostic Tool - This checks your computer's memory hardware for errors
* Command Prompt - This opens a Command Window
15/ Click on the Option you require and follow the onscreen prompts
If no repair options are available your PC manufacturer may have replaced the tools or customised them. Check your Computer Manual before proceeding.
1/ Start your PC
2/ If your PC has one operating system Press and Hold the F8 key as your PC starts. If the Windows Logo appear you will need to start again
3/ If you have a dual boot system a Boot option menu will appear. Highlight the Vista operating system and Press the F8 key
4/ In both cases, if all has gone well, an Advanced options screen will now appear
5/ Highlight the repair Your Computer option and Press Enter
6/ Select a keyboard layout, and then Click the Next button
7/ Next select your user Name and Enter your Password, then Click OK
8/ The recovery options should now appear
thank you very much for your help!
