Describe the problem

To much processes by one application in Task Manager and CPU is used 60-80%(very laggy).

What have you tried?

Nothing.

Poblem is when windows has started, and give me to much error dialogs on desktop "Only one instance is allowed" and when I look in Task Manager i see process ALARMC~1.EXE is open more than 3 times, sometimes go to 20 processes from ALARMC~1.EXE. One time it was AlarmClock.exe process.

Following is just what I find in www.file.net:

AlarmClock.exe is not essential for Windows and will often cause problems.AlarmClock.exe is located in a subfolder of "C:\Program Files". Known file sizes on Windows 8/7/XP are 1,011,712 bytes (83% of all occurrences), 1,003,520 bytes, 4,988,928 bytes, 4,227,584 bytes or 999,424 bytes.

The program has no visible window. It is not a Windows system file. AlarmClock.exe is able to record keyboard and mouse inputs. Therefore the technical security rating is 43% dangerous, however you should also read the user reviews.
If you still experience problems with AlarmClock.exe, you can use the software publisher's support site or uninstall the program using the Control Panel ⇒ Add/Remove programs ⇒ Smart 6 B or at BIOS.

First off all, I would make sure you computer is not infected with malware. Can you please perform a scan with these 3 programs:

1. Malwarebytes Anti-Malware Free: Free Anti-Malware Detection & Removal Software
2. HitmanPro: HitmanPro 3 - SurfRight
3 ESET Online Scanner: Free Virus Scan | ESET Online Scanner | ESET

I don't have info on ALARMC ~ 1.EXE, it is probably a malware.
Can you check the path of this file?

ALARMC~1.EXE is part of Realtek HD Audio Sound Effect, it can be malware if you do not have Realtek HD Audio Sound Effect installed.
so scan with your antimalware

No, this is a wrong info: the source of this info is sponsored by crap software.
