Sophos AntiRootkit detects CFP stuff as unknown

Help for v3
#1

What is this stuff in temp that Sophos detects:

Area: Local hard drives
Description: Unknown hidden file
Location: C:\Documents and Settings\Damian\Local Settings\Application Data\Comodo\ComodoFireWall\Temp\CPF8F.tmp
Removable: Yes (but clean up not recommended for this file)
Notes: (no more detail available)

Area: Local hard drives
Description: Unknown hidden file
Location: C:\Documents and Settings\Damian\Local Settings\Application Data\Comodo\ComodoFireWall\Temp\CPFF5.tmp
Removable: Yes (but clean up not recommended for this file)
Notes: (no more detail available)

Is this something that should concern me? Or is this just no biggie and Sophos detected it as a false positive?

#2

Sounds like false positives to me. I actually have never heard of Sophos. I use NOD32.

Oh, I only looked into Sophos cause some of the peeps I talk to on Speedguide.net, said to take a look into it. Anything is better than Norton or McAfee. But yes, I love NOD32 I have it on my laptop and my desktop uses Avira AntiVir PE.

Just figured I would check how Sophos detects and I was wondering cause no1 else came up with anything. Thanks!
