Hi again,

I guess I need to say a little more about false positive alarms then. So here we go...some words of explanation: Sometimes, anti-virus applications, or other security related software, can create false alarms. Over the years, creators of security software have come up with more clever methods to detect and fight malicious software. Anti-virus programs don't just look for already known viruses now, since this is very limiting and can fall short with so many new viruses being released every day. They also use intelligent, heuristic methods now to detect behaviour that might indicate activity of malicious software, e.g. certain system-level operations. Unfortunately, this has the downside, that sometimes the activity of completely legitimate software can be wrongly detected as harmful. This is probably what happened here. Plus, there's also the possibility that if a security software scans for malware in the "old-fashioned" manner (i.e. searching for specific strings) a legit software happens to contain a specific virus signature and is therefore identified as malware.

If you want to read further material on security software in general and false alarms in particular, you can read a bit more here (just a few examples):

Well, I hope this info helped and I could allay your concerns.  :-)
