the image is not clear, however the exe process under system32 is trying to stop/modify luallcallbackproxy.exe, which is not normal.

Any process which tries to stop and modify symantec related process the tamper protection alert are observed.

Symantec Blocks / Logs the Application when it find the Application to be suspicious.

C:\Windows\system32\taskhost.exe is a Suspicious file which is trying to stop the Symantec LuCallbackProxy.exe

Could you please Submit the Suspicious file to the Symantec Security Response Team on:


You can Later on create a Tamper Protection Exception as well for the same.

Regarding to, there is a malware which uses a file with the same name, but at another location in filesystem. The file in %system% should be the right one - so that must be a false positive.

Contact support about this.

@Lisa123: ACSService.exe is from china and a known spy/info stealing application! Have a look at this:

Your Tamper Protection was right. Get rid of this software, it is not to be trusted!

It looks like Advanced SystemCare is attempting to tamper with Symantec. From their product page, it looks like the product has some security features. Running two security products on the same system can cause problems, and is not recommended.

Advanced SystemCare

Defends PC security with extra protection Enhanced

Detects and analyzes Windows security environment. Scans and removes spyware and adware using up-to-date definition files in order to prevent spyware, hackers and hijackers from installing malicious programs on your computer. Erases and updates your PC's activity histories.

As Thomas has mentioned, it is not advisable to have 2 security products on the same machine. And here ASC is trying to modify SEP. If ASC is important, you may have to create exclusions for tamper protection.

The below link might help.
