I'm using 10.0.1.
An update of one of my portable apps tripped one of our IDS signatures. The signature triggers on a user-agent string known to be used by various malware.
SRC: GET /project/portableapps/Google%20Chrome%20Portable/Additional%20Versions/GoogleChromePortable_17.0.963.46_online.paf.exe HTTP/1.1
SRC: User-Agent: NSIS_Inetc (Mozilla)
SRC: Host: downloads.sourceforge.net
SRC: Pragma: no-cache
SRC: Connection: Keep-Alive
Link to the IDS rule:
My advice would be to change the portable app update tool and have it provide it's own User-Agent string.
