The following file does not exist on my computer.

C:\Users\Paul\Appdata\Local\Temp\DXB347.tmp\infins t.exe

Yet every time I remove it from Zone alarm it is immediately re-created. Is there a way to find out what is creating this file access request. I have tried everything I know of and can't work it out. All scans coming up negative for Virus, Rootkit and Malware, nothing suspicious in Hijackthis log. Nothing that I can see in processes or services. Help!!!
