Today this AR scan alerted me for the first time. It said that a hidden file was found - C:\Windows\system32\process.exe. I have a file like that in my system32 directory, but it's not a hidden file, nor a running process. It's a command line process utility from Beyondlogic.com. It's sometimes treated as a virus file. Was Avast really meaning this file? I ignored it, and after that i scanned my system with Malwarebytes' Anti-Malware and with F-Secure Blacklight rootkit detector, but nothing was found. Should i be worried?
