This is surely a good name for a program – Windows Instant Scanner. However, the application doesn’t actually scan your system. It is not able to remove threats from your system. It can’t identify potential vulnerabilities. It is not capable of preventing your system from being infected. This is all because Windows Instant Scanner is the infection itself. The rogue program is the one that claims to be some powerful system protection utility, whereas these are all but deceitful promises not supported by the real system cleanup. The action of it is similar to many other malicious applications that share the same interface.
