Trojan loves Firefox?

I bought this computer from a 'professional' refurbisher. None of my other computers show a Trojan infection, and MS Security Essentials shows a Trojan in the 6/6D cache of Firefox. I've tried MSSE, Malwarebytes, SuperAntiSpyware, & Trojan Remover. Only MSSE sees the Trojan, and after I delete it it pops back up. Manually deleted file, then even uninstalled Firefox & re-installed it. After a day, the Trojan was back. Thoughts, please? Thanks. Chuck

Chosen solution

Hi,

It could be a cache entry from a visited website. You can upload the particular file to VirusTotal for a comprehensive analysis with many different scan engines. If MS Security Essentials has an option to send results you could send it and if it was a false positive the warning would likely disappear at the next signature update. You can also do a scan with another online/standalone AV scanner:

Norton

Trend

Kaspersky

F-Secure

Bitdefender

Thanks for taking the time to reply! After several more scans/deletions, the file has stopped appearing (thanks, Lord!).
