A few day ago, this problem started occuring,after i've removed a dll file that avast reported-resident protection went down,and can't be started,when i open avast antivirus,it say disabled,i can change it to standard or high,but it just gets back to disabled..when i opened services.msc, all avast services were stopped,although they are set to start up automatic and when i try to start them,it says it couldn0t be started because it didn't response(reports error:1053) I've tried reinstalling avast,but it didn't help,i still can't get resident protection..please help if you know how..my operating system is win xp SP2 and i haven't had any problems with avast until now..
