The only 2 you need running are explorer and systray, all else are not needed. goto start, run, and type msconfig, enter, then select startup tab and uncheck all unnecessary programs followed by apply, then reboot. Advised to recheck settings after reboot, I have often seen that realplay will cause an issue and might want to save it for 2nd round disabling. If issue you will have to go into safe mode to reinitailize certain programs that will cause conflicts and will have to test 1 by 1 till boots properly. You have a rediculous amount of stuff running!! Some of the programs realplay is the realplayer and will still work by navigating to the program vs loading the tray icon at startup. Logitray is mouse or keyboard software that might or might not be needed at boot up but doubt it. Incd is cd burning software nero and again dont need it running in backround, just navigate to it. Rnaapp is utilized only when the modem is initiating a call to the internet (remote network access _____, ____, protocol) qttask and loadqm I believe are quicken software, others I have seen that are not needed for various programs. I do suspect that ptsnoop might be a trojan program but not sure. While in startup tab of msconfig you can expand the explination of the program to get a better understanding of where the program points to to determine it's origin for removal, programs that are no longer used then uninstall them to reduce bogging down. You can also check your performance once end taskingthe programs by right clicking on my computer, select properties to view cpu usage. Good luck. Most other posters advise
www.lavasoft.com (or .de) to remove trojans, I havent used this site yet but it comes highly reccommended.
