Hello there, I’ve been trying to find why was my PC getting lags and I finally found the culprit, it looks like for some reason Avast uses 100% of my CPU at some random moments (but most of the time at night) and last for a couple of seconds.
I didn’t had this problem on my old computer (Intel CPU, win7) but I actually have it on this one (AMD Ryzen 5 1600 CPU, win10) and Avast is on gamer mode, this happens when I’m playing a game most of the time, it would be nice if I could get an explaination because I’m really clueless about why it is happening.
