Thanks for this discussion,
I have worked for 3 weeks on this question.
Every 2 or 3 days I have 2 TMP files found as VIRUS in that directory.
This make me very afraid.
I thought it came from an unsecure UPLOAD ?
Can you confirm these files are not VIRUS ?
I do not understand your recommandations above with requestfiltering , CFIDE etc...
I am not enough knowledgeable to understand this.
If I leave the configuration as it is, with these files files coming regularly,
IS THIS SAFE ???
A big thanks for your answer or recommandation.
Pierre.
