Trojan infection + logfile attached. HELP PLEASE!

I have F-secure, and it continues to find Trojan.Sirefef.BV, but every time I restart my computer, it's back. It can't seem to get rid of it. Plus I have the free version of Malwarebytes, and it scans and finds nothing.
I noticed today that when I go to use Google search (browser: Firefox) it brings me to a captcha page saying something about my IP address has been identified for something (I can't get it to happen this second- so I apologize). When I enter in the captcha, it just brings me to another and another.
Anyways I ran the Hijack this program and the results I got are attached as a .txt. I've never tried this before, so I hope this is what I'm supposed to do!!

hijackthis logfile.txt

I would very much appreciate any help!!!
Thank you

Posting Logs as Attachments

May I draw your attention to the topic: ALL USERS OF THIS FORUM MUST READ THIS FIRST, which you should have read before posting for help.

The instructions for running DDS found HERE, state how we need you to post the logs, so we can help you.

The section here explains why you should not post attachments unless the helper assisting you requests that you do so.

If you still require assistance, please start a new topic and copy and paste your DDS logs (DDS.txt and Attach.txt) and wait for a new helper. Thank you for your understanding.
