Hello everyone, I've got an issue with Avast. My Behavior Shield is often turned off when I boot up my computer (I'm on Windows 7), or turns itself off shortly afterwards. I always turn it back on right away, but it worries me a bit. I've got the latest free build, I think: 17.5.2303 (build 17.5.3585.182), but it has been doing that for a few weeks now, even with previous versions. Originally, it would do it only occasionally, but now it's almost every day. I've also been getting BSODs this month (four of them, three were BAD_HEADER_POOL and one was DRIVER_IRQL_NOT_LESS_OR_EQUAL), but I'm not sure the two issues are related in any way. I've noticed that Avast does the same thing with my mother's laptop (the Behavior Shield thing, I mean, she doesn't have BSODs).
I've done a lot of different scans between now and the first time I've seen the disabling happen. Smart Scans, Complete Scans, and a bunch of scans with MalwareBytes too (Threat Scans, Custom Scans with all options enabled, Hypers Scans). Nothing ever turned up. I've even tried the Rkill software, in case it was some kind of virus or malware which hid itself from detection, but the program hasn't found anything to terminate. What should I do?
