Hello All, I am looking for the location in the gui to edit protocol options and have not been able to locate it. I have recently upgraded to 5.2 and it appear a lot of stuff has changed or moved. I get notifications about downloads that file limit is exceeded and it categorizes that event as subtype of virus?? Makes no sense to me. I only want notification emails when a virus signature gets a hit. Anyone have any ideas about why this my be behaving like this? I just don' t understand how a file size (which I suppose I will need o change) would trigger an event with a subtype of " virus" .

    What netmin has posted is more in line with 4.0. MR3 (which I am more familiar with).
    Under 4.0. MR3, that section looks like this...
     config firewall profile-protocol-options      edit " default"           set comment " all default services"               config http                  set port 80                   set options clientcomfort                  set comfort-amount 100                  unset post-lang                  set oversize-limit 5              end              config https                  set port 443                   unset options              end              config ftp                  set port 21                   set options no-content-summary splice                  set oversize-limit 5              end              config imap                  set port 143                   set options fragmail no-content-summary                  set oversize-limit 5              end              config pop3                  set port 110                   set options fragmail no-content-summary                  set oversize-limit 5              end              config smtp                  set port 25                   set options fragmail no-content-summary splice                  set oversize-limit 5              end              config nntp                  set port 119                   set options no-content-summary splice                  set oversize-limit 5              end              config im                  unset options                  set oversize-limit 5              end      next  end  
    Under 5.0, tried to edit " default" and add " set oversize-log disable" but just gives me an error. Only options I can set under " default" is
     (default) # set   comment             comment  replacemsg-group    Replacement message group.  extended-utm-log    Enable/disable detailed UTM log messages.

    The box you have noted here is not checked on my FG. I was hoping that was the issue but no dice on that one. :(

    I used the " config firewall profile-protocol-options edit " default" ' set oversize-log disable . We shall see if that does the trick. I will let you know. I really appreciate your time and answers. Thank you folks.

    The ' default' profile was meant as an example of course (in case you are using multiple/different proxy option profiles). Other areas that could be checked: are you using a DLP sensor? What logging options are used in the AV profile? Could you also post an anonymized log entry? It was already asked - is the email sent by your FGT or a FortiAnalyzer event setting?

    The notification is being sent by the FG. The only event setup in the FAZ is a high memory event. The notifications look like this when they come to me in an email. " Message meets Alert condition File Block Detected: iR3245_Series_HTML PC_02262014.exe Protocol: HTTP Source IP: ************* Destination IP: ************** Email Address From: Email Address To: date=2014-09-02 time=15:12:23 devname=*********** devid=************** logid=************ type=utm subtype=virus eventtype=oversize level=notice vd=" root" msg=" Size limit is exceeded." action=passthrough service=HTTP sessionid=54608523 srcip=************* dstip=************** srcport=3828 dstport=80 proto=6 direction=incoming filename=" iR3245_Series_HTML PC_02262014.exe" url=" http://downloads.canon.com/navilp/iR3245_Series_HTML%20PC_02262014.exe" profile=" Forsyth Protocol Options" user=" guest" group=" SSO_Guest_Users" agent=" Mozilla/4.0" DLP sensor is turned off. I looked in the AV profile and I do not see any logging options listed there. I am going to look once more.

    No it wasn' t. I thought I had turned off globally when I turned it off earlier. So, I have now turned it off in those options and we will see if the notifications stop. Thanks again for your help everyone.
