SSDPsrv.exe Service / Seclogon eating 40% CPU

I have started playing Hardcore, and so i have decided to eliminate as much lag as possible.

Since quite a few battle.net updates ago my Diablo 3 has been lagging more then usual, but i haven't given it much thought until now.

When i loaded up my resource monitor to see what was causing the lag, i noticed that my services were using up almost as much CPU as d3 was, specifically the SSDP Discovery service. I did some googling, and after deciding i did not need this service, i disabled it and restarted my computer.

After starting d3, a new service started using the exact same amount of resources, named Seclogon or Secondary Logon service. After disabling this one too, i got stuck at "Updating Blizzard Update Agent" when attempting to start D3. I found users having similar problems on the forums, so i followed the instructions, and checked that my Agent and CLient versions were current; they were. I deleted the battle.net folder from my prgmdata folder, and after the launcher replaced the folder, it got hung up on the same "Updating Blizzard Update Agent" message again.

So i re-enabled seclogon and restarted again. D3 launched just fine this time, but i am still looking at 40% of my CPU going to this service every time i tab into Diablo. It only uses 10% or so if i am tabed out of D3, or if i am logged out of Bnet. When D3 is not running, these processes use nothing.

Is this normal? I am using an AMD dualcore CPU, a gigabyte mobo, and a Nvidia 260ish GPU. I would be more then happy to give you any other information, please ask for what you need!

Cynic ,

Windows' Secondary Logon Service is required for Diablo III to run but it shouldn't be taking any resources to do so. On my machine, just now, I checked and it's using 0 CPU resources while in the game.

I'd suspect malware or a third party app you're using in the background perhaps is causing what you're seeing.

Try booting in selective startup once and see if it happens again.

Use Malwarebytes to scan for possible malware too. The trial version is fine for that. Be sure to update it after installing and run a Full scan, not the short one.
