It's placed in C:\Users\pcname\AppData\LocalLow\Conduit\xbpkyzj\uzhrqtd.
This runs in 3-4 instances, per Task Manager. Can't kill - it regenerates. Brings web browsing to a crawl.
No ideas what else it does, Googling it gets no hits.
It has Google Chrome as the task manager Description.
Kaspersky rescue disk doesn't find it, nor does MSE. I didn't do a full C drive scan with Kaspersky because it takes an hour and I needed the PC.
Had my PC back in 5 minutes by restoring an image.
Probably plenty of crap like that out there. I was on "questionable" websites.
Second time I had it.
