Kaspersky 6.0 reported Trojan.generic when upgrading to 4.07

When upgrading to 4.07, Kaspersky Anti-Virus 6.0.3.837 reported is-U6Q69.tmp as Riskware with Trojan.generic

Verify checksum of the download files. If it matches, than it is false alarm.

Kaspersky 7.0 reported Trojan.generic when upgrading to 4.13 for me too.

How can I verify if the downloaded file checksum is the same?

You can use for example Windows tool md5sums.
