The "process.exe" file that is alerting Avast! may be a part of the smitfraudfix tool. If this tool is on your system or was ever downloaded and used on your system. The process.exe file may even stay on system if smitfraudfix tool is removed.
I ran all the top malware / trojan / anti-virus programs and none of them alerted on this "rootkit" file.
You can do a search within your Windows OS for the process.exe file. When it appears in the search box, click on it to open it. A command screen will appear very briefly,and it shows the author's name. Go to this site "
http://www.beyondlogic.org/consulting/processutil/processutil.htm" to learn what this file does. It appears this is a file that helps the smitfraudfix tool to defeat the malware infection.
NOTE: when Avast! alerts on this process.exe file....DO NOT HAVE AVAST! REMOVE THIS PROCESS.EXE FILE...... Tell Avast! to ignore it...permanently.
I had Avasti remove the suspicious file the first time I encountered this issue and it screwed up my computer to the point where I had to do a complete format and reinstall of my operating system.
Again...TELL AVAST! TO IGNORE THIS PARTICULAR ALERT...AS IT SEEMS TO BE A ISSUE WIH AVAST! AND NOT A TRUE MALWARE INFECTION...hope this helps.
