Lagg recuring

Hello,

Since few days I realize that I have problems with my Pings lagg who are bad at best 66 to 99 most often.

So I play with 99 ping and I easily drift to 132 ping see more!

I do not know if it's my new antovirus Kasperskiy?
Thank you in advance (:

click kaspersky icon, chose options, gaming profile, enable gaming profile

It's a little better now.
Less lagg but my ping is not improved, hmm

If you have not others suggestions, thanks

Try turning it off completely. If that gives you your normal ping back, then you've found the problem. I won't advise you to not use an AV though.
Also, if you've installed any new programs that use the network regularly, that may also cause lag.
Apart from that, I'd say it's simple overload on the route from you to the servers you play on. In that case there's nothing you can do from your end.
