Access to a website is blocked with the a message from IWSVA giving the reason as "Virus infected temporary block".

IWSVA blocks any URL that it determines to be infected and returns the message “URL is blocked” for any subsequent requests. The block will be active for 4 hours by default, although this can be configured.
To configure the default block time:
- Log on to IWSVA either directly or with SSH as "root".
-
Edit the configuration file /etc/iscan/intscan.ini as described in the KB article: Editing configuration files of Linux-based products.
Look for the parameter "infected_url_block_length" in the section [Scan-configuration] and change the value to a different number in order to change the blocking time (in hours).
-
Restart the HTTP scanning daemon with the following commands:
/etc/iscan/S99ISproxy stop
/etc/iscan/S99ISproxy start
If you are confident that the detection of the URL is infected and a false positive, submit a false positive case on our Malware Support portal.
To make this blocking persistent over the service restart, the Scanning Daemon creates a temporary configuration file infectedB.ini during normal shutdown and stores the current blocking configuration in it.
It is also possible to turn off temporary URL blocking by setting disable_infected_url_block=yes in intscan.ini. However, this is not recommended because it might affect the amount of resources used by scanning the same content again and again.
