part of the eRecovery software shipped with the Acer notebooks
Seems to be a driver of somekind uses (among others?) for Acer's eSettings Management (B.S.) software
int15.sys belongs to Acer's eRecovery ships with Acer notebooks. It helps you to create a recovery disk that contains a complete back-up image copy of all the files, drivers, programs and other components that are on the computer.

Agree with kfazz; BSOD seen "attempting to access memory after it has been freed"

Best practices for resolving int15 issues

A clean and tidy computer is the key requirement for avoiding problems with int15. 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 int15.sys 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. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
