1) additional protection for your computer, 100% compatible with other antivirus!Most of the antivirus can not be installed together with other anti-virus, it is because the antivirus is designed for primary protection on your computer. In contrast to SmadAV, SmadAV is the type of antivirus are designed as an additional protection, so 100% compatible and can run well although there has been another antivirus on your computer, in this case SmadAV serves as a second layer of defense. SmadAV has its own way (behavior, heuristic, and whitelisting) in detecting and cleaning viruses that will further enhance security on the computer.

4) Cleaner and tools to clean the virusSmadAV also able to clean the virus that has infected your computer and fix the registry is modified by a virus. Other anti-virus is usually not done cleaning the registry so the computer has not returned to normal after cleaning the antivirus.

Note: Not all types of viruses can be cleaned SmadAV, SmadAV is still not able to clean the virus type or types of rootkits penginfeksi program (eg: virus Ramnit, Sality, Alman, Virut, etc..) Because this strain has blown most of your program files . Our focus now is to thoroughly cleaning the virus types other than those two types (eg: virus WormShortcut, Cervical, MSO, Brontok, etc..)
