Hi. I don’t know is this a virus or FP Virusscan.jotti
Most probably it is infected.
Which is the file path? Is it your Firefox installation folder?
I would also suggest you check it against VirusTotal.com as it has more scanners (43), so may well prove more conclusive. Can get a bit busy at time though.
Where did you download it from ?
Well we know the MD5 hash and we know that it is firefox.exe
Then we also know it was downloaded from here: download.informer.com My Top Files = malware
