ESET couldn't handle it, but quarantined then successfully deleted via AVG
one instance of b.exe is associated with a trojan used in an advertizing scam that uses the system's internet connection to actively download audio advertisements and open web-browsers to sponsered addresses

It is a worm. It will make your computer experience background advertisements. If you tried running MalwareBytes anti-malware, it disabled the process and deleted the program itself.

I know that it wipes your entire computer, it's not fun to have. Also, there is A.exe

It pops up every now and again and tries to open some unknown website. Since I don't know what these websites are I cannot discern how dangerous this is, but I don't intend on finding out. Not too bad, but annoying.
steals more than half my CPU cycles and 50mbs of memory with no apparent purpose. Noticed that ads randomly pop up in IE8 (firefox is default browser). May have something to do with that stupid 'evony' game that you see fucking ads for everyfuckingwhere on teh internets now. Also advertises for that game.
It was hidden in HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Is a adware process, can copy to registry, ect
  Jake Fisher  
In my case, I found it to be in C:\Documents and Settings\ USER \Local Settings\Temp directory. There were also a.exe, a.dat and c.exe
renos.exe trojan
It just appeared one day, it doesn't SEEM to do anything so DELETE it at first chance (close the process through taskmanager first if you cannot delete it straight away).
b.exe is a execultable file that disrupts you while web browing. Sometimes out of nowhere even while not having a Internet Explorer window, it still manages to to peak in and play audio advertisement, and some audio streams (i.e. the Adams Family Webisode) you wonder where it comes from then you open Task Manager under the Process tab you see a bunch of b.exe and iexplorer windows even if you dont have an open window, getting rid of it can be challenging becuase even with the Norton 2010 version it still wasnt able to diminish the b.exe just quarantine and comes back. Very Annoying!!!

Best practices for resolving b issues

A clean and tidy computer is the key requirement for avoiding problems with b. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the b.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
