I'm not 100% sure if is Zhider, but Windows Vista Home Premium always crashes whenever I have Zhider active and I am away from the computer for more than 30 seconds. What can I do?
To make sure that this is the program that cause the crashes, try to uninstall it. If the crashes stop, it is advised that you update your program to the latest version before you install it again on your PC. If the problem persists, try to do a full scan of your PC using an antivirus utility that has its database updated. Also, it is advised to download and use the Malwarebytes program for a full scan. Try not to use any registry cleaner tool because it can damage your PC at this point.
