I foolishly responded to an 'urgent' update to Firefox this past weekend and now have the trojan mentioned above: Trojan-PoweLike!bat.
The solution you provided to zman32 above is geared toward Internet Explorer users.
Do you have a variant for users of the Firefox browser?
Since it is now October 11th, are there any new factors in removing this trojan?
Catdaddy is busy with the after-effects of Hurricane Matthew so I'll butt in here.
Look up this document https://community.mcafee.com/docs/DOC-2168 and scroll down to the Farbar section.
Run the software and post its log on the forum mentioned there, or any of the ones listed above under the Hijackthis section for expert analysis and advice.
I did run Farbar last night unsuccessfully, probably because I didn't think to turn off McAfee on-access beforehand. It became unresponsive and I had to shut down the PC. Upon turning it back on, it ran DSKCHK and had to make a lot of fixes. I'm assuming this is because the two products were fighting each other. Unless you have other thoughts, I will try again tonight after work, turning off McAfee first. It was pretty scary -mostly the thought of losing all my files. I'm wondering, would RKill stop the trojan long enough that I could backup all my files?
Also, I'm not clear about Farbar -which option should I select: scan, registry, etc.? Any details here would help a lot.
Turn off Access Protection in McAfee then until the scan is finished.
If this is Windows 10 ChkDsk runs whenever there's an I/O read or write issue - I've experienced that myself - a nuisance.
You could ask support but they would insist on charging you for the Virus Removal Service.
