qbv.exe - can't seem to remove w/ Avast?

My computer got somehow infected with a Trojan. Avast keeps finding qbv.exe file. Am trying to remove, but keeps coming back. Suppose i have to manually clean the registry - how do i do this (am only mildly computer savvy)? Any other suggestions aside from registry cleaning? Thank you!

Great, thank you so much! I assume once i followed these instructions, I post the scan logs here, under my topic in the forum?

No, do not post them.
