Conhost.exe is in hundreds and taking up 100% of my CPU.

Hello, I've got a problem. Currently my computer is running VERY slowly because the CPU is at a 100%. I'm using AVG currently and I scanned multiple times. I specifically scanned the Windows folder where Conhost.exe is located but no luck.
If anyone has a insight on this please let me know how to fix this.
Thanks.

I think Conhost.exe is only loaded if you start a command line, i.e. if you run cmd.exe. Try closing all your command line interface (cmd.exe) windows.

I tried doing that, but I also forgot to mention that Netsh.exe is also running in the hundreds.

Netsh.exe is a command line tool, so in principle can only run if there is a command line open. It is only for ipv6 I think, so you probably don't even need it. Just end the process in task manager.

It says the handle is invalid, and doesn't end. Also there is about a hundred of them and 200 conhost

Will deleting my conhost.exe cause any harm to my system?

start with booting into safe mode f8 and run malware scan and anti virus scan. you may if you have a virus boot off a rescue cd to remove it. run msconfig and turn off everything but your anti virus is start up. also run a hijack this and post the log here.

Don't physically delete conhost.exe. It is required for cmd.exe to function. I assume you have tried rebooting your PC? After booting, how rapidly do these rogue processes appear in task manager? Are they there the instant the desktop has loaded?

Ok, I booted in safe mode and used the antivirus. Apparently a malware got in and was deleted, so now I'm all fine and dandy.
Thanks a lot guys.
