Hi and welcome to
TSF.
I am sorry to be the bearer of bad news but unfortunately, at least two of the malware are identified as trojans with backdoor capabilities, keyloggers/infostealers which give intruders complete control of your computer, logging key strokes, stealing information, etc. I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to alert them to your situation.
Though the Trojans have been identified and can be killed, because of their nature, your PC is very likely compromised severely and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of Trojan, the best course of action would be a reformat and reinstall of the OS. In all honesty, if this were to be my computer, I would reformat and reinstall Windows XP.
Please read these for more information:

However, if you do not have the resources to reinstall your computer and would like me to attempt to clean it, I will be happy to do so but it is not at all guaranteed that your computer will be completely rid of malware regardless of what anyone can really do.
Should you have any questions, please feel free to ask.
