Having Problems ridding my laptop with Rootkit.MBR.Sst.C (Boot image)

Please help

I have tried manually to remove from registry and can not find the needed things to delete, have run various programs to remove.
Have included the following scan reports:
MBR & OTL

Thanks
Denyce

[*]Check the boxes beside Verify Driver Digital Signature, Detect TDLFS file system and Use KSN to scan objects , then click OK.

[*]Click the Start Scan button.

[*]If a suspicious object is detected, the default action will be Skip, click on Continue.

[*]If malicious objects are found, they will show in the Scan results and offer three (3) options.

OK lets try another check … Are you experiencing redirects ?

[*] Download RogueKiller and save it on your desktop.

NOTE: If using IE8 or better Smartscreen Filter will need to be disabled

[*]Quit all programs
[*] Start RogueKiller.exe.
[*] Wait until Prescan has finished …
[*] Click on Scan

https://dl.dropbox.com/u/73555776/RKScan.GIF

[]Wait for the end of the scan.

Nothing evident there … I think Avast is hitting on the partition 4 due to the size. Although I would expect this partition to be hidden and active if it was bad

Could you go Start > Run and type in the following command followed by enter :

compmgmt.msc

In the page that opens select Storage > Disc Management
Then take a screen shot of that page and attach it here

HI I’m sorry but won’t let me print screen

Denyce

Use the snipping tool… http://windows.microsoft.com/en-gb/windows7/use-snipping-tool-to-capture-screen-shots

Ok ty here it is

OK can you see the partition marked RAW could you right click that > Select Properties and snip the tab that opens

done

Denyce

OK now right click that partition again and select delete

Once done re-run Aswmbr

You are wonderful! It’s gone!

Denyce

It was a kind of false positive due to it being such a small unformatted partition

Any further problems ?

Not a one! Thank you so very much!

Denyce

Run OTL and press cleanup to remove it and associated files

done
