It is a Trojan and the [Drp] I would say is for dropper, indicating that it probably drops or downloads other files ?
However I would confirm the detection.
You could also check the offending/suspect file at:
VirusTotal - Multi engine on-line virus scanner Or
Jotti - Multi engine on-line virus scanner if any other scanners here detect them it is less likely to be a false positive.
You can't do this with the file in the chest, you will need to move it out.If it is indeed a false positive, add it to the exclusions lists (
Standard Shield, Customize, Advanced and Program Settings, Exclusions) and periodically check it (scan it in the chest), there should still be a copy in the chest even though you restored it to the original location. When it is no longer detected then you can also remove it from the Standard Shield and Program Settings, exclusions.
Also see
(Mini Sticky) False Positives, how to report and what to do to exclude them until the problem is corrected.
I use QuickBooks pro 2000, copied from a friend, and have not used since I started using Avast.
However, since the origin of QB is suspect, you got it from a friend, who got it from where. We obviously can't condone how you came by this program, but when not got from an authorised source it is quite possible you could have also received an unwanted gift.
