Malware Cleaning/ a few concerns (RootRepeal etc.)

Hi folks, I'd like to let you know that your Malware Cleaning Guide has helped me out a lot in the past.

Now, I have a used computer recently given to me by a relative and, after buying and installing Avira Antivirus, found that it had a Trojan Horse on it (Avira found and was unable to delete 338896.SYS).

Note that I uninstalled Avira as part of my preparation to run the Malware Cleaning scans.

Here are my concerns:

1. After running Super Anti Spyware and maybe Malwarebytes but prior to running Combofix, I found that the computer would no longer reboot normally. In other words, choosing "restart" causes it to shut down to the point of getting an initial Intel screen, but I have to manually shut it off and turn it back on to get it to come up again. I have just tested it again and continue to have this problem.

2. When running Combofix, I let the computer sit overnight before manually restarting it (I gave it time since the Combofix instructions said to let Combofix reboot it).

3. In the interests of backing up the computer before doing anything, I bought a Seagate FreeAgent Goflex external hard drive, which shows as the F:/ drive on the computer. I am concerned that Combofix deleted the autorun and setup files off this new disk; I had backed up the C:/drive and not the new F:/drive and would like to get the files back that came with the new F:/drive. Also, after the scans as below, I am now getting periodic pop-up boxes that say: MemeoBackgroundService.exe - Application Error [I am quite sure this has to do with the Seagate background software]: The instruction at "0x74985dfe" referenced memory at "0x00000020". The memory could not be "read". Click on OK to terminate the program

4. After running Combofix, in order to reconnect to the Internet I found it necessary to uninstall and reinstall my Netgear N600 Wireless USB Adapter WNDA3100. So for better or worse, I reinstalled this after running Combofix.

5. I was then unable to run RootRepeal, which indicated it was initializing but would then hang. I rebooted and tried again with no luck. Maybe because of Netgear but I can't be sure?

Therefore, I skipped RootRepeal and have now run MGTools. Attached please find the logs that I now have; I appreciate any input you can give me on this computer and how to resolve the few issues I have remaining.
