Specs: Windows XP service pk3, AMD ATHLONXP1800
Dear Folks,
After having done some web surfing activity, I just lost all computer files extension code [like my computer, control panel, system tools,registry, web browser, Internet explorer, Microsoft office software {word, exel, PowerPoint, acess etc}]; even it knocked out the Avast virus software too. They all look like worms file; and whenever I click any of them; the message pops up by showing that,
Windows cannot open this file;
File: rundll32.exe
To open this file, windows need to know what program created it, windows can go online to look it up automatically or you can manually select from a lost of programs on your computer,
What do you want to do?
Use the web service to find the appropriate program
Select the program a list.
Ok cancel
Under above those circumstances, how do I recover the fatal problem?
Should I do the repair installation for WinXp pro?
I will be waiting for your important reply!

First download and burn an Antivirus LiveCD, which boots it's own operating system so that windows is not running, and scans your system for viruses.

When finished, reboot your computer in normal mode, download and install fresh antivirus software, even if there is already one installed to your computer.
When installed, update the antivirus definition files.

Download and install Malwarebytes and let it run.
While it's scanning your system, the newly installed antivirus software also scans all files for infection.

After that, download and install Ccleaner and let it run.

When finished, reboot your computer and check if it's working as expected.

Hi, I already downloaded the AVIRA and burn it into Cd by poweriso, and during the cd rom booting time I press enter for scan, after finish the scan, the pc boots again, and the computer monitor screen dark forever, and by the way i left the pc on for 7hrs for finish the scan, the compuer monitor screen is still dark, it is no working. Lastly, I did press the hard boot button for reboot again.
The all files of the System is still file extention codeless, and I downloaded Malware program from the web, whenever i try to open to scan the system, the message says Windows file association to find file software.
I am still confused what to do?
I will be waiting for your reply!

First of all, what was the result of the virus scanning?
If there were system file infected by a virus, that my cause a black screen on normal system startup.

There is no boot scan, avira does.
You may have to choose an option at the very first screen of the avira boot disk, to be able to choose the correct screen resolution.

Hi Paulsep, My corrupted disk got 1168 by 768 resolution for winxp; and my downloaded avira rescue software does not give any resoultion figure mode, and only advance mode provides resolution mode, and even after fix the resolution mode it loaded the linux bird pic and then downloaded something but as soon as it reboot again, the same situation arrives like screen got dark forever, and I am thinking that it may be messed up resolution configure!
Thanks for your reply!

Ok so when you get the linux bird pic on screen, in the upper left corner, the screen resolution isn't the problem.

Anyway, could be some kind of incompatibility or maybe hardware problem like bad RAM.

You may want to try another Antivirus LiveCD.
I suggest to try Kaspersky Rescue Disk.

Try also the advice given in #7. To my mind the symptoms don't fit too neatly but it's easy to try (assuming the computer will let you).

Not easy to think of some easy magic fix to sort these all out. If it was the work of a virus then that could have screwed up anything. The only simple thing I can suggest is to go back to the link given in #7 but this time run the LNK fix instead.

As regards MalwareBytes you should try changing it's extension from EXE to either COM or BAT. This applies to both "the download exe" and to "mbam.exe" (the program itself in MalwareBytes program folder after it is installed). This rename facility is deliberate because often viruses stop exe files from running.

Always pop back and let us know the outcome - thanks

Disk image just a snapshot at the state, you made the disk image.
You habe to make additional backups of you data files.

Restoring an image brings you back to the date, you have created it.
You have to make all the missing Microosoft updates after that and the restore your data files, to bring it the the last actual state.

Re #16

For that very reason I make manual copies of anything I regard as important (or could be useful to keep) onto an external USB hard drive. Mine is only about the size of a mobile phone and can be plugged into any computer to see the data. It is only 100GB but I expect there are higher capacity external USB drives about by now.

It takes a little of my time to keep it up-to-date but I regard the effort as well worthwhile.
