What is the best way to deal with a suspected bot problem?

Anti-virus software was originally developed to detect and remove computer viruses. However, with the proliferation of other kinds of malware, antivirus software started to provide protection from other computer threats. In particular, modern antivirus software can protect from malicious browser helper objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious layered service providers (LSPs), dialers, fraud tools, adware and spyware. Some products also include protection from other computer threats, such as infected and malicious URLs, spam, scam and phishing attacks, online identity theft (privacy), online banking attacks, social engineering techniques, Advanced Persistent Threat (APT), botnets and DDoS attacks.
