Malware Removal - Initial Scans completed

Hello
I read the Read and Run Me First and followed the correct link to the Windows XP Malware Removal page and I think I have all the logs required which I will attach here. Firstly, thank you for such a well written and elaborate set of instructions.

Now, to the problem. I had this problem 2-3 days back and basically a virus seem to have struck my external HDD. Its capacity is 1 TB and now the name is all scrambled and is made up of strange characters. Also the contents of the HDD have been converted to these strange files and folders with scrambled character names. I am posting screenshots of all these pages to show you exactly what I mean.

I would really appreciate if you could help me with not only removing the malware/virus that has struck the HDD but also preferably recovering most if not all the data.

Thank you,

And here are the screenshots I told you about in the last post.

"H virus1.jpg" is a screenshot of the name of the corrupt drive and "H vius2.jpg" is a screenshot of the now damaged contents of the said external HDD - which is a Seagate GoFlex 1TB External HDD, the kind which needs an external power supply : http://www.seagate.com/external-hard-drives/desktop-hard-drives/goflex-desk/

Hope this helps.

Thank you,

I tried the scanning using Norton. The internal Hard Disk is clean as a whistle. As for the external hard disk, it scans these new big files created by the virus which are ~400 and says there are no infections. Which is kind of crazy as there are obviously a few if not many virus and malware occurrences in the external HDD.

No, the external hard disk has never been plugged into any other PC and I regularly run scans for both my internal and external hard disk(s).

I will try to run the Kaspersky products you recommended in your reply, @Chaslang, thank you. I will post results ASAP.

As of now, I have disconnected the affected hard disk from my computer, will plug it in again for the scans.

Thank you,
Sohum-Bilawal

EDIT : And yes, only the files on the external drive were affected.

 

I ran both the Kaspersky scans. The RectorDecryptor scanned files after I chose the 'Changed' option at the pop-up window which asked me whether file extensions have been changed. It would not run any scan if I chose 'Not Changed' and selected one of the files.
I have attached the Report.

The xoristdecryptor report that I have attached shows the issue I have been having with it. I select 'Start Scan' choose one of the files from the external HDD and any file I select, I get such a report(attached).

Hope this helps,

How do I run a disk error check?

All files on the hard disk have been affected it seems. Nothing remaining. And I'll try to add a file or two to the external HDD and tell you what happens.
