Is your computer a Simda Bot?
Kaspersky Labs Simda Bot IP scanner is a free online service that checks whether your computer is part of the large network of infected machines or not. Then, if your computer has been infected with Simda, it may contain malware, spyware and adware.
On the other hand, if your IP address was not found in the database of infected computers does not mean that your computer is safe from any risks. Malicious programs can remain on your device without your knowledge for a long time.
