Trojans detected, looking for help

Hello all,
On the latest Avira system scan for this computer, the virus "BOO/Tdss.O" was detected. I followed an internet search to a windows forum post that recommended using Windows Defender Offline. I booted WDO up, which found another virus, "DOS/Aruleon.E," but did not find the BOO/Tdss.O. WDO was unable to remove the DOS/Aruleon.E, and Avira is still reporting the BOO/Tdss.O upon start up. Another internet search for the Aruleon virus brought me here, and I have followed the "Read & Run Me First" up to step 4 of removal, and am attaching the files I can. Unfortunately, the HitmanPro log is too big to upload here. I would deeply appreciate any help the community can offer.
Thanks for your time and help in advance!

 

Okay, cleared, rebooted, and rescanned. Here is the new Hitman log.

 

I unfortunately don't have too many details, as this is my coworker's computer, but she has been complaining of popups, new tabs being opened and redirected in Firefox, and general slowness. I also noticed while scanning that the computer will constantly "tab out," in that it will act as if the active program has been switched, although no open windows will change. I have not personally seen any popups or redirects, but the initial Avira and Windows Defender Offline scans did remove some adware. Furthermore, Avira has not had any alerts for the BOO/Tdss.O virus since I let Hitman remove what it found, but I have not had a chance to run another full scan yet.
Thank you for looking into this, and I hope some of this info helps. I will be keeping an eye on this thread over the weekend, but I won't be back in the office until Monday morning, so I won't be able to work on the computer until then.

 

Okay, I have run full scans with Avira, Malwarebytes, and Windows Defender Offline, which have all been clean. I also reran the scans in the Read First sticky. Roguekiller had some flags in the registry, but all other scans were clear. I'm including the new logs in case you need to look them over. However, the "tabbing out" continues to be an issue. Is it possible that there is a missed virus causing this, or should I start looking at software/hardware issues?
Thanks!

 

Okay, I'll take care of that and see how it goes. Thank you so much for your help!
