I am not sure what Trojan I have. All I know is, is that Malwarebytes picked up on it a day ago and I had quarantined it. It's till quarantined. I searched Google and found that I needed to "Pulicize" my folders, and do I did, and the hidden folders shown that there were so many shortcuts of my "Documents", "Pictures" etc, etc.

I'm sure there are tons of Reg Keys with a bunch of trojans I suppose. I really want to get rid of this. I suppose I caught it browsing the web, or that time when my brother downloaded something while looking for a good Music Downloader and got it then. I noticed when I logged on my computer, it shown Screensaver icons on the desktop and said "Freeze.com"

I searched about Freeze.com and it mentioned that there was Malware, and stuff, on that site and to stay away. I have a feeling I might have to take my computer back and get a new one, because I have had this problem before, and could NOT get rid of the Trojan virus I had. It's been here for probably a week or so now, and could have created so much more than I realize, and it may be too late.

I have ran Malwarebytes and it only picked up on Trojan.Agent, and it was in my Temp files folder.

C:\Users\Brittany Forrester\AppData\Local\Temp\.exe (Trojan.Agent) -> Quarantined and deleted successfully.

(end)

There is one that was I think: C:\Users\Brittany Forrester\AppData\Local\Temp\IWantThis.exe
.exe didn't show in the quarantine list, unless it's still the same thing, and it doesn't need to have the same title.

Please help.

Thank-you in advance.
I love Malwarebytes. TWICE, has this program told me that I had a Trojan, and was on the road to helping me. It even blocks sites that aren't bad or "seem" malicious. I have been using this program for like 2 years and it's my #1Software. When I get some money, I am definitely going to contribute to the acceptor.

Attaching HijackThis log. I never finished the scanning, because I am not sure if I should "Analyze" and hit "Fixed checked."
I will wait for your reply.
