dell backup recovery\components\dbrupdate\hstartexea virus, or is this false positive?

I can't answer your question, but you might want to check out this thread:

What's the use of HStart in Dell computers? http://en.community.dell.com/support-forums/software-os/f/3526/p/19436721/20053470.aspx

I don't have hstart.exe (or Dell Backup and Recovery) on any of my Dell computers using XP or Win 7. Probably because I uninstall all Dell software that comes pre-installed (I've never found any of  it useful).

But others have uploaded a file named hstart.exe to VirusTotal for testing by multiple virus scanners, and you can see one such result here:

As you can see, ESET considered it a variant of  Win32/HiddenStart there also. Other scanners found it suspicious also; many others did not.

As long as your system is working well, I don't think you need to worry.

"But then I clicked check potentially unsafe applications, that is when it was found..."

The problem with many installers --- including CCleaner (Standard version) --- is that they include offers for "bundled-software" such as Google Chrome, Google Toolbar, McAfee/Symantec scanners, ASK toolbar &etc.   Users have to be very careful running these installers, especially to UNcheck any PRE-checked boxes for programs they don't want to include.

Fortunately, in CCleaner's case, they also offer a SLIM version on their Builds Page, which does NOT include any bundled software http://www.piriform.com/ccleaner/builds

I ticked the box enable detection for potentially unsafe applications in ESET NOD32.  I usually kept it at unwanted or suspicious applications.  I am very careful on running installers, because of extra software they have set up to install with the original software you checked.  I have been using CCleaner for many years.  I do not use all of the features.  Mainly I use it for cookies only.  I clean the cookies, but the cookies I need, are not deleted.  Thank you for the link to the slim build.  I will check that out. 

Thank you!  When I tried to find it, it didn't show.  ESET NOD32 said my machine was clean.  But then I clicked check potentially unsafe applications, that is when it was found the first time, last night.  I scanned it also with Malwarebytes, and it did not show a virus, or problem.  So, I had ESET scanner on pause, trying to find what this was.  I was afraid it was a false positive, so I hit pause, until I could find more.  I could not find anything more on here, I guess I didn't hit just the right search.  Finally last night, I just let ESET clean the file.  ESET also has a problem with the CCleaner.exe file, but if you scan it without that box ticked, it does not show a problem.  It also does not like PhotoScape.  I downloaded another CCleaner file and it said it was clean.  I am going to check that box again, for unsafe applications today, and see what it does.  It wants to clean, or delete.  If I just typed in hstart.exe in windows explorer, nothing comes up.  (this was as soon as I saw the scan in progress, and it was marked a threat.  Thank you again for these links.  I guess there is a vulnerability with this in Backup and Recovery.
