Hope I'm not the only one dealing with an influx of buggy Win10 systems!

 

This one is aggravating. File Explorer keeps loading at startup. The client can't say for certain if the issue was present before or after upgrading from Win7. This wasn't the primary issue- there was malware present on the system. I have run Adwcleaner, Malwarebytes, TDSSKiller, Rogue Killer, and aswMBR scanner. System is returning clean logs now.

I also installed Revo Uninstaller and removed Adobe Acrobat DC and CutePDF, as I've read that Adobe will cause this issue, and since there were 2 PDF viewers install I suspected some conflict.

 

I have tried using regedit, but the two suggestions I found from Microsoft- the reg entries don't exist for win10.

 

Startup Folder is empty.

 

I am considering running Farbar, but beyond that I'm at a loss.

At least on my system with 10 it is a default startup. I find it in the menu whether left or right clicking or using the windows key.

It is also by default in the task bar when I start/boot up.

This is on my system not nesisarily any body elses system.

It's sounding like a common occurrence. But there HAS to be a way to disable it!

What I don't get is I have a demo with the full Win10 loaded and it doesn't boot with File Explorer.

Have you tried looking in Autoruns (free from here:  https://technet.microsoft.com/en-us/sysinternals/bb963902.aspx ) to see if you can stop it.

 

Beyond that, If infected, I'd suggest posting over in the Am I Infected forum:  http://www.bleepingcomputer.com/forums/f/103/am-i-infected-what-do-i-do/
Please read the pinned topics at the top of the forum for instructions on how to post there.

I'd suggest having the folks in the Am I Infected forum have a look at this first - as they're more likely to be able to spot this sort of behavior.

If they can't find anything, then we could try a Process Monitor trace.

Process Monitor is free from here:  https://technet.microsoft.com/en-us/library/bb896645.aspx

And here's an article on how to enable boot time logging:  https://www.msigeek.com/6231/how-to-enable-system-boot-time-logging-using-process-monitor-tool

Stop the trace as soon as the explorer window pops up.

Then zip up the log and upload it to a free file hosting service such as OneDrive or DropBox
