Anyone know what these are and how to remove them without any antivirus?
What is Win32.Zafi.B
Win32/Zafi.B is a worm spreading via e-mail and P2P networks.
Zafi.B worm is a moderately destructive worm that may cause antivirus and security products to stop working. It also may overwrite executables of installed security products. Zafi also disables RegEdit, MSconfig and the Task Manager and may also launch a DoS attack against several Hungarian web sites.
You can yourself search your computer manually.
Trojan.Zlob.B is a Trojan horse that opens a back door and allows a remote attacker to perform various actions on the compromised computer.

Technical details
This malicious program is a hacking utility. It is a Perl script. The size of infected files may vary from 12KB to 69KB.Payload
This script is an IRC bot which is used to search for Remote File Inclusion (RFI) vulnerabilities.
Depending on the commands received, the bot can:
wipe log files
search for sites with RFI vulnerabilities. In order to find a site, the bot is given a keyword. It then uses the keyword with the following search services:
http://www.google.nl
http://busca.uol.com.br
http://www.alltheweb.com
http://it.ask.com
http://search.aol.com
http://suche.fireball.de
http://search.lycos.com
http://arianna.libero.it
http://search.yahoo.com
http://search.live.com
If sites are found which contain the substrings "buterfly" and "uid=" in the address, the malicious program ctreats a request which redirects the address to the following link:
http://linknet*****.com/source/cmd.txt?
The contents of this file will then be run on the site's web server. This provides the remote malicious user with access to the server.
The script also contains the following string:
Yogya Ceria Scaner Bot Created By eviL-Zone -= evil =-
Delete the original malicious program file (the location will depend on how the program originally penetrated the victim machine).
