Mufanom - how to get rid of it?

Since cleaning the hard drive of a friend (detected over 150 different viruses!) I seem to have infected my system with something.
Every day when I turn on my computer I get a message that Comodo has detected TrojWare.Win32.TrojanDownloader.Mufanom.GEN@142105750 each time it seems to be in a different .dll file, which Comodo detects and deletes.
However, I guess there’s some underlying virus in the system which is creating these .dlls Comodo apparently isn’t detecting or removing this. Any ideas as to what I can do manually?
Googling it takes me to a load of sites that tell me to unregister certain .dlls but these files don’t seem to exist in my system (I’m guessing they’re ones created at random by the underlying virus).
Any help much appreciated.

Yes, I use Dropbox.

I’ve attached the report. It’s an html file, but I’ve changed the extension to .txt so I can upload it.

Hello AsherJac;

step 1 Could you go to start > programs > acc > Run as admin > command prompt and enter the following command

del /f /s /q %temp%

step 2

cleanmgr

Once You see “More Options Tab” > Clean Up (Bottom Button)

step 3Also Open CIS > Antivirus > Scanner Settings > exclusions and add
C:\Program Files\TeraCopy\EnterKey.exe

Once Completed; Then Go to start > programs > acc > sys tools > system restore > create > Name it something

once completed repeat step 1 only

and then restart and repeat step 1 again; then downloal malwarebytes antimalware
from here Download Malwarebytes Anti-Malware 4.5.15.296 for Windows - Filehippo.com
and post a report once completed scanning;
OR
Do a complete scan with CIS

Ok, that’s all done. Malware bites found a few things. I’ve removed them.

I’ve attached the log.

Just to make sure you’re clean; you can scan with SUPERAntiSpyware and Hitman Pro.

Thanks Deadman, I’ve now scanned with Comodo, Malwarebytes and Kaspersky (as well as Microsoft’s One Care Live previously) so I think I’m ok. Will bear those in mind for next time though.
