The Task Manager in Windows XP shows that tcpsvcs.exe uses 90-100% of my CPU. This slows my computer to an unusable degree. I have done everything I can with viruses, firewalls, hijack this etc and as far as I can tell my PC is clean. R H Wright
As its name suggests, tcpsvcs.exe is a Microsoft program that provides internet protocol (TCP/IP) networking services. Sometimes the same name is used by a piece of malware such as the old Backdoor.EggHead Trojan, but your checks should have eliminated this possibility. There's a discussion at File.net (file.net/process/tcpsvcs.exe.html) that suggests possible solutions.
