Corrupted File

I ran SFC scan to check my file system for errors that might have caused some issues I’m having with Avast. The log file showed me that the file “icardagt.exe” was missing, though doing a search for the file, I found it in Windows\System32 but there is no extension after the file, while under properties it is listed as an application. Did some recent malware issues do this and will just adding the .exe on the end fix it? Maybe the file is corrupt and if so, where can I find a clean copy of this file if it’s even needed. My computer seems to run OK, just had an issue with SafeZone that Avast tech support said was due to some issue on my system.
