Heur.Corrupt.PE mfc45.dll Virus or false positive?

Hi,

I’ve quarantined and submited to comodo for analysis the mfc45.dll on my machine. I’ve uploaded to Virus Total and 6 out of the 43 engines detected a virus.

Here’s a link to to my scan on virus total: http://www.virustotal.com/file-scan/report.html?id=0762deb17faf8726fba79f80de785dca5a6a2d1e37b6302dfb2c740ac5d2b82f-1299608585

Best Wishes,
KWP
