FileRepMetagen [Malware] (Kaspersky updater)

Hi all, my Avast free blocks Kaspersky Software Updater from updating Opera browser claiming that it contains malware FileRepMetagen [Malware]. Is there anybody who can help me to find out what causes this? Is it simply false positive? I didn´t Google anything specific about this issue.

Here is the screenshot

You can use http://www.avast.com/contact-form.php for reporting potential false positive (archive or site wrong detections).
Also, it would be useful to submit it to www.virustotal.com and post back the scanning link.
Thanks.

I located the installation file at C:\Users"MyName"\AppData\Local\Temp . Here is the VirusTotal link https://www.virustotal.com/cs/file/8872068cc594c1095551e9f578b0d287d821aaa02f43d4dfd864eb58a632f5b8/analysis/1439275452/.
