Download Smadav 2018 Free Antivirus can scan your registry for nasty information, but not generic errors like a true registry cleaner would. The program's installation process and license agreement seem to be written in Indonesian and you won't get a chance to change the language to English until you've completely installed the program. SmadAV2013's layout organizes all of its features into easy-to-understand tabs, but it's not very easy on the eyes. It doesn't help that there's a big ad for other developers' programs taking up a lot of space. The program's virus scan took about 40 minutes to complete, which isn't terribly fast compared to competitors. It makes up for that lack of speed by giving you a process manager that's more detailed than Windows and letting you lock any of your hard drives.
