Sygate. If you remove from startup list, it will still run as a system service (unable to delete without hijack this or safe mode) and blocks ALL internet connections.. had to do a system restore after removing it to restore my internet connection.. be careful with it..
Excellent Firewall, easy to use. The Perfect replace for XP SP2 internal firewall Kio
It is part of the Sygate Firewall program. While I have been told by friends with post-secondary training in computers that I have nothing to be worried about, I also sometimes find that when my computer freezes and I go CTRL+ALT+DEL to see which of my running programs are bugging, I will often times see "SMC.exe [not responding]". I don't know if this means that my copy of SMC.exe needs replacing, or if it just means that it's not working at the moment... Talis
It belongs to Sygate Firewall. Don't remove. L.U.H.A

i have installed sygate after i was attacked by trojan through internet as a precaution, but just after installation i started getting Application error from smc.exe. It was just like i got during my system was a patient of trojan spywares. so in my view its something suspicious as a burden for the system. cybersupam
Sygate Firewall. Not dangerous. Runs as system service. EVERYONE needs a firewall like this!!! Trammel
It eats 100% cpu
it is an important component of Symantec Endpoint Protection  See also: Link Daymon
Uses 30% of my cpu and I can't turn the bugger off! People will hate me for saying this, but Windows Firewall does the job just as well as uses much less CPU. Sam Illingworth
Its an EXCELLENT FIREWALL but it uses lot of CPU if you download 10+ torrents at same time... test0r
also part of Symantec Endpoint 11
Delays my internet logon by about a minute. Never knew what it was but, like Talis, it's often in Task Manager saying "not responding". I've been clicking "end task" whcih I now presume ends my firewall. If so, I haven't noticed any change in performance. Didn't realise it's probably slowing down my whole (Windows 95) system and causing most my crashes, especially on closing down. steve
Sygate security firewall, alters traffic, saps resources, pointless WVR
Good firewall, However uses a lot of cpu. Dr J.

Does very many in/out writes. Part of the lag problem. There were 2500 in/out writes in 5 minutes on my computer. May be a great firewall but makes your machine run like dirt. If that is good more power to you. Jeff Hale

It's also common if you have Symantec Endpoint Security installed and running (or maybe similar Norton peoduct) AnGus

part of symantec antivirus, it can be laggy just after system boot/reboot, no chance to hijack or infect this if used in Symantec antivirus, other part of symantec antivirus will block those attacks G. v. Munster
It has completely jacked up my computer using 98% of the available CPU the entire morning. Two thumbs down !! Ocho the Clown

Sygate is much easier to use and is more effective than Zonealarm and should be #1 choice. Carpenter

Symantec Endpoint Protection BuR
Causes 500-4000 page faults / second in my system slowing everything badly! Janne
Symantec Endpoint. Immediately after my company installed on my pc performance took a nose dive. Typically runs at 50% of cpu. Apparently has been a problem for at least 3.5 years. Joseph

Sygate Firefall Process. It will take almost 100% of cpu time Suresh
During system boot with sygate installed it can take as much as 98% CPU usage. When it has completed it's tasks and sygate is fully loaded it calmes down to very little CPU usage. Small price to pay for good firewall protection. Badeye
