I've tried deleting this file and it keeps coming back. Looks like very advanced spyware to me....
Spywarebot catches the Dealio every time I open IE
If you get malware disguised as it, it can be very serious. If you randomly find it installed on your computer, delete it immediately! It disables computer shutdown, task manager and possibly other ings I haven't check out yet. Delete this virus ASAP
Hijacks some search and other browser behavior Does not uninstall DealioKit1-stub-0.exe and dealio.exe
  the mechanic  
its a bit of botch and remains dormant until it finds a way to bypass security then it will try to install itself whenever you open explorer and disguises itself in many different ways but they all have same signature according to eTrust Scan

Dealio is also the name of a toolbar, which helps users to compare prices and makes sure it doesn't let you overpay

Uninstalling Dealio - After running Malwarebytes Anti-Malware, it was identified as spyware. To completely get rid of it, I had to search for it using Regedit.

My keyboard driver was disabled by malware, and the malware scan brought up a slew of "dealio" files to remove.

Best practices for resolving Dealio issues

The following programs have also been shown useful for a deeper analysis: ASecurity Task Manager examines the active Dealio process on your computer and clearly tells you what it is doing. Malwarebytes' well-known Banti-malware tool tells you if the Dealio.dll on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
