Recently when I go to task manager, Performance tab, My
CPU usage is always at maximum. And my computer is sluggish.
When I look in task manager, Processes tab, in CPU
column I notice that image name tcpsvcs.exe is constantly
using 99% of my processor power. To get my computer to
work correctly again I have to right click tcpsvcs.exe
and end the process. Then it is ok unless I restart my
computer again and I have the same problem again. Can you
tell me what this is how I stop it.
Looks like you might have picked up a trojan??? My machine
has
tcpsvcs.exe service present in task manager, but it is not
using any
CPU time.
Also something else new is occurring that might be
related. When I run an ipconfig /all I get two new
adaptors that I didn't put in. they are;
Tunnel adapter teredo tunneling Pseudo-Interface
AND
Tunnel adapter Automatic Tunneling Pseudo-Interface
Help, what is going on. What do I do.
Those two interfaces are made up when IPv6 is installed. If
you've installed any programs which use IPv6, they might
have enabled the IPv6 interface, it is disabled by default.
If you are SURE you haven't installed any program that might
use the IPv6 interface, you can easily uninstall it. After
you uninstall it, reboot a couple of times and check to see
if it's re-installed, if so, you probably have a trojan. To
see if IPv6 is installed, just type "IPv6" in a command
window (DOS box) and press "Enter". If IPv6 is installed
you'll see a list of commands you can use, if not you'll get
a message "IPv6 not installed" or " to install IPv6 type
IPv6 install and press Enter"... I'm not sure about that
message. I can't test it because I have IPv6 installed and
I'll just get the help screen.
If you want to disable IPv6 to see if it is causing the CPU
usage you're seeing, open a command window, type "ipv6
uninstall" and press the "Enter" key (no quote marks, of
course)... you must be logged in with Administrator
privilege to do it. If a program you've installed then stops
working, you'll probably have to re-install it to get all
the interfaces configured like they have to be for the
program to work correctly.
If you already know how to use netsh from a command window,
skip to the bottom...
If you want to look at IPv6 before doing anything dramatic,
type each of the commands below into a command window. Press
the "Enter" key after each command. After each command name
below is what the command line will look like after you
press "Enter". I'll put ^ where you press "Enter", my
remarks start with "//"..
//First, type netsh and press "Enter"...
c:\whatever your path is>netsh^
//Prompt will change to "netsh>", type "interface" and press
"Enter"
netsh>interface^
//Prompt will change to "netsh interface>", type "ipv6" and
press "Enter" (yes, again)
netsh interface>ipv6^
// prompt will change to "netsh interface ipv6>", type a "?"
mark and press enter
netsh interface ipv6>?^

If you have one machine connected to the Internet and one or
more machines connected to that one in a Local Area Network,
you might consider having IPv6 installed. It will enable you
to connect to any of your LAN machines from the Internet
using only one IP address that you have to pay your ISP for.
