Kaspersky And Firefox

[Tefler]

I've just updated to Kaspersky 2016 on a Windows 10 and a Windows 7 computer. When using Firefox, it seems to have slowed both systems down massively. Is there any way of speeding it all back up again? I think the problem seems to be that Kaspersky is checking each URL we try to use, but that may well not be what is happening!

There's also a message on both computers saying "Kaspersky Protection could not be verified for use in Firefox and has been disabled". Does this mean the computers aren't protected when we're browsing?

Kaspersky may be doing its first full deep scan so may take a while.

Also have you got any other anti virus or security software on your PC that may be causing a conflict. This can slow a PC down.

i updated to windows 10 3 weeks ago my laptop performance is excellent in fact better than before.
will be interested if there is an answer to the 2nd part of ur question i'm getting the same message .. i think its to do with an addon from firefox tho

I've had Windows 10 for a while now, Bernie, and agree that it's fine - the problem is with Kaspersky 2016 and Firefox. There's no other antivirus fighting with it, VHG. There is a problem with an add-on in Kaspersky in that 'Kaspersky Protection could not be verified for use in Firefox and has been disabled' - not sure what that's all about, either!

First full scan will take a while depending on how many folders it finds. Can take 1 hour approx. (400.000) Firefox messages are plug ins etc. Once computer is scanned I do full scan once every couple of weeks and quick scan every couple of days.

having just looked on kaspersky site do not worry kaspersky is working and protecting our pc's its to do with an addon from firefox
which is being looked into

Thanks for your answers, but I'm still needing to know if there's anything we can do to speed up Firefox with Kaspersky running. We don't seem to have anything like the delay on either IE or Microsoft Edge.

Assuming that Kaspersky has finished doing its full scan process you can then initially test to see if an add-on is causing the issue by starting Firefox in safe-mode via 'Help'>'Restart Firefox with Add-ons disabled'. See:- http://www.wikihow.com/Start-Firefox-in-Safe-Mode

If Firefox then works ok you can then restart Firefox in normal mode and using the Firefox Add-on manager disable each add-on in turn to attempt to isolate which one is potentially causing the issue, (at a guess, most likely a Kaspersky Add-on since you see the problem on two separate Windows systems').
