What is ASCService.exe?

The genuine ASCService.exe file is a software component of Advanced SystemCare by IObit Pty, Ltd..
"ASCService.exe" is one of three background processes in IObit's Advanced SystemCare security and registry cleaner software. Its role is harder to define than the other two. ASC has three versions, free, Pro (paid), and Ultimate, and ASCService will be present whichever is installed. ASC Ultimate includes the Bitdefender antivirus engine. Some question the ethics of IObit, a Chinese company founded in 2004, saying that their installations include extraneous toolbars, PUPs, and even malware. Uninstalling Advanced SystemCare is said to be simple with their Uninstaller program, but elsewhere said to be incomplete and requiring complex steps to remove it fully.

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 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
