Hello all, an alert from avast! popped up says “Rootkid Found” but the file name is pointing to MBR: \.\PHYSICALDRIVE0\PARTITION3 and the action to take is Delete Now or Ignore. I am fairly certain that on my one harddrive, Partition 3 is where the OS resides. So if I choose to “Delete Now” is that going to harm the MBR and not let me load into Windows? And if I choose to Ignore, is this a real root kit somehow on my PC or a false-alarm?
Any help would be appreciated!
Hi lets check it out
Download aswMBR.exe ( 4.1mb ) to your desktop.
Double click the aswMBR.exe to run it Click the “Scan” button to start scan

Nothing happens when I double-click the program. Tried in regular and safe mode windows.
OK lets have a look at your partitions
Do the following: [b]Start[/b] -> [b]Run[/b] type [b]diskmgmt.msc[/b] Click "[b]OK[/b]"Disk Management will open.
Click and hold the right side of the Disk Management Window and drag it to the right until you can see all the columns.
Take a screen Shot of the Disk Management Window and attach the screen shot to your reply.

How is the computer behaving now ?
Unfortunately I get endless BSOD in Windows and even Safe Mode. I am considering giving up and formatting - but here’s the question - with this being a “bootkit” virus, is it possible that even after a format and Windows reinstall that the virus will appear?
As it was a mbr malware you will need to reformat the disc to ensure that it has gone
When you get the Blue screen what is the error reported
The typical blue screen “a problem has been detected…” STOP error is 0x followed by a series of zeros and 7E.
Thank you for your continued assistance…
Are you able to access the safe mode menu ?
If so select Last Known Good
Does that get you back ?
Do you have a windows CD as we can then use that next
