After removing HttpDataSource.dll and A0000003.exe, several problems appear.
1.All minimized windows disappeared from the task bar
2.Hot keys are not working. Such as I cant use ctrl + c to copy any texts.
3.My computer slows down. It is the most obvious when logging in to my window users.
4.Avast is not working any more. Cant scan cant do anything.
I am using window xp and I am in great need of help.
you could do a boot scan with avast. but if that doesn’t work, you can use Dr. Web live cd (free) to do a boot scan.
Where did you remove them to, the virus chest? If they are still there you can rescan them safely.
From the GUI click on “Maintenance”…click on “Virus Chest”…right click to rescan. If they turn up clean you should be able to put them back where they were. If “not” you can send them to avast! for further scrutiny.
