These are almost always false positives. The checks are based on checksumming and sometimes a perfectly innocent .exe will match the checksum of some virus/malware. The .exe is rebuilt nightly and changes slightly between builds, so you may want just retry after a day or so.

(The AV vendors are behaving pretty irresponsibly in these matters, but as long as it only hits a patch build, I don't think anyone cares enough to take action.)

My antivirus software, AVG Internet Security with all the latest updates, aborted the connection, saying that some malware was found - please see the attached Figure 1.

I immediately asked the AVG software to scan the file; it found something suspicious and sent the file for analysis in their labs. Some hours later, AVG said that the file was malicious, and sent it to quarantine; I am not able to figure out which kind of malware was supposed to exist in the file - please see the attached Figure 2.
