I had AVG antivirus (free) before, but it caused some conflcits with Java wanting to download any files (without giving any notice). So I uninstalled AVG and installed Avast. I used to have Avast before AVG but I think I uninstalled it also due to some BSOD problems.
After installing Avast, I didn't reboot my PC, and after some minutes the first BSOD appeared. The system now rebooted and continued to use it without problems. Days after, I turn on my PC, start my browser and minutes after browsing, BSOD appears. After reboot, it works perfectly. Now, today, this morning, the same happened. It's working perfectly after reboot.
Right now, this problem is a minor hindrance, but I would still appreciate to know what's going on.
Thanks.
