IME each of us has a different "stew" so to speak and Avast may run just fine on other users computers, but perhaps not yours for some reason. I have seen this situation with my favorite antivirus Kaspersky. On some computers it's just fine and on others it clearly caused performance issues. For those people I have had them try Avira (paid version) and it didn't have as much of a negative effect on performance as Kaspersky did on their computers. You could give Avira a try. I suggest doing a good clean uninstall of whatever antivirus you want to remove via one of their clean up (uninstall) tools after a uninstall via Control Panel. Revo uninstaller is also a good uninstaller for these situations IMO.
