What to check (for KIS and KIS for Mac) :

1. Visit web sites, including popular web resources

Setup product:

Variant 1 - Only web antivirus enabled

Variant 2 - All components except SafeBanking and ParentalControl is enabled



There should not be any significant performance downgrade on opening web pages. No engine\product failures any of:

-Traffic cannot pass through product

-Traffic is corrupted by product (only a part of web page is downloaded)

-Product turns off web antivirus by any fatal error

-Product stops working completely


2. (Dangerous! For advanced users). Turn off anti-phishing protection in browser. Visit latest links from http://www.phishtank.com/. Most of links will be blocked by databases or cloud protection (red banner). Heuristic detection is marked by yellow banners.


In case of problems please send:

Traces, dumps, steps to reproduce (or URL, if it causes engine\product failure). Try to reproduce the issue after update from public update source.
