Przy uruchamianiu komputera zajmuje mi 99-100% procesora przez co komputer uruchamia się 30 minut a dalsza praca jest możliwa dopiero po wyłączeniu tego procesu

All I know about this is that it suddenly began taking over my PC upon startup, utilizing nearly 100% of the processor and causing the system to freeze until I can disable it using Task Manager. Even so, it takes a while to disable it since everything runs incredibly s-l-o-w. This happens every time I boot the system now, and I can't do anything until I disable it.

ASCService.exe took 25% of my CPU (AMD quadcore), not for minutes, but the always. I comletely removed ASC 7 tot stop this.
It is responsible on my windows7 computer for updating my search engine list in Internet Explorer to insert Conduit Search". I renamed it and the above behaviour stopped.

Best practices for resolving ASCService issues

A clean and tidy computer is the key requirement for avoiding problems with ASCService. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the ASCService.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
