I booted up my pc as I usually did. Logged onto my account and tryed to access the internet browser. No luck, so I went on MSN because it isn't a browser and asked every contact that was online. I got a lot of help and that worked. Well now, I can only use my Windows Vista Game browser because it doesen't detect it as a browser. I tryed to download Camtasia studio because I belived that would improve my videos a lot and I would get more channel views on my youtube account. Well, after I downloaded it and ran it, it started installing. I waited for it to install and about fifteen seconds later, it said I didn't have administrator rights, Well, after that, I did a Hijack This log. I got a error saying that it coulden't scan the hosts file. That what got me even more mad. I tryed searching administrator hack on google and found this code that hacked the startup so I could use a command propmt that was unprotected. Well, it didn't work. Then I tryed manually doing it. It worked. After that I rebooted my computer. Well, it skipped it. I tryed creating a botuser using the command prompt but it was a limited user and not a administrator. After that, I tryed removing the files to the avast chest. However, when I looked in that folder again, it was still there. But it was in the chest as well. Thats when I really got mad and decided to post here for help. If you want I can tell you the file names but I still don't know how I became a limited user.
Just some extra info:
1. How was it detected? What was scanning, you yourself or the back-ground scanner? When did the message occur on a download, unzipping, opening a file, mail or mail-attachment, etc.?
Myself, I coulden't use internet browsers and I wasn't a administrator anymore.2. What was the source of the file, where did the file come from?.: e.g. address, URL, source.
I don't have the link. Sorry.3. When was it downloaded or received?
I didn't download it. It was recived after I shut down the computer and went to sleep and when I woke up, it was on there.4. What is the exact file name with extension.
There are multiple files that I am aware of.5. What was the exact wording of the message that the AV program came up with? This is important for later.
It didn't detect it as a virus.6. Now go back and do nothing yet. Scan the particular file once again with your AV product.
Nothing found again.7. Check with an on line scanner or update to jotti for a second opinion. Jotti resides at

8. Go get informed ask a Virus Encyclopedia or Virus Central, put a question on a forum.
