I’ve had a problem with the Barclays Bank site as described above. I got it working by doing the following: Open up Kaspersky and go to Settings - the little gear wheel. Click on Network Settings. Find the Traffic Processing section and untick the ‘Inject Script into web traffic’ check box. Then save your new setting. Once you have checked if your problem web site is working, make sure you reverse this change by ticking the ‘Inject Script’ check box, until you next want to use the site. Hopefully a bug fix will come along soon, although I’ve just installed a Kaspersky Total Security update and that didn’t include it. Good Fix. Many Thanks.
