This sounds like a False Positive,
You need to report the false positive to Kaspersky, the link to the procedure is contained in Guru Fax previous message. No report, no fix.
How to diagnose and/or report antivirus/antispyware false positives
NOTE: Only valid for ZA versions 10 or above.
First seek confirmation of the false detection; upload the file(s) to www.virustotal.com
. If confirmed:
Go to the advanced settings of the antivirus/antipsyware section (Scan Option) and UNcheck "Enable automatic treatment". Restore the file from Quarantine and next time the threat is detected, you will be able to exclude it ("ignore always" or "ignore once").
Send the file(s) in a password protected zip to newvirus at kaspersky dot com. Subject: false positive. Include password in the e-mail. For faster response sign-up to kaspersky viruslab support at: https://my.kaspersky.com/en/support/viruslab
and submit the file under the "Send request to Kaspersky Virus Lab" tab.
Please also report the name of the detection in the e-mail.
You can exclude the files from the 'on-access' scanning under the advanced settings of the antivirus/antispyware section (Exceptions)
You can exclude the files from the 'on-demand' scanning under the advanced settings of the antivirus/antispyware section (Scan target)
REMEMBER to remove the exclusions once the false positive has been corrected!
