Microsoft Security Essentials keeps informing me of "Trojan:DOS/Shetwirl.E" that it can't remove; may have to do with it apparently being located in the boot sector, giving the paths "boot:\Device\Harddisk1\DR1" and "boot:\Device\Harddisk1\DR1\(MBR)". MSE pops up now and again saying it cleaned it, only a few minutes later to say that it detected the same thing again. I've noticed its log also says: "Microsoft Security Essentials encountered the following error: Error code 0x80070032. The request is not supported." I haven't used MSE for very long and haven't been experiencing any obvious unusual activity (no strange programs suddenly installed or caught running on task manager, no unexplained lag, no weird errors, nor anything else I can think of) so I'm not sure if it's some false positive or the virus isn't actually a major cause for concern or what. Prior to having MSE always on I'd scan for maintenance about once a week or so with a different antivirus and Malwarebytes and they never picked up this sort of thing either.

Has anyone actually heard of something like this, if I should worry about it, if it is in fact a virus, etc? I don't want to mess around with trying to get rid of it unnecessarily due to its apparent location and lack of undesirable effects. Also if relevant, the main OS I use is Windows 7 (from where I found the virus) and I have a dual boot with Windows XP on the same physical drive (also a factory partition is located on that drive) and have a second physical drive for only storage purposes; not sure which drive it's on.

No, It's taking 4 or 5 days I see ,we are that busy. You WILL be answered.

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRL Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
