What is ASC.exe?

The genuine ASC.exe file is a software component of Advanced SystemCare by IObit Pty, Ltd..
“ASC.exe” is the main executable module of IObit’s Advanced SystemCare (ASC) security and registry cleaner software. It will be present whichever of ASC’s three versions, (free, Pro, or Ultimate), is installed. It is a background Windows service, started by the ASCTray service after it adds the ASC icon to the system tray. “ASC.exe” can be stopped using the icon menu “Exit” option, or via Task Manager. 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.

Best practices for resolving ASC issues

A clean and tidy computer is the key requirement for avoiding problems with ASC. 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.
