Hi, sle3pingz.

For background, see Time to check your DNS settings? | ESET ThreatBlog. Then go to DNSChanger-Check - dnschanger.eu to check if your computer had been affected by that botnet.

Otherwise, if your computer scans clean by your security software, you have security updates installed, have an up-to-date antivirus software, a firewall and third-party software us updated, your computer is not part of a botnet involved in a DDoS attack.
