According to Trusteer a security company, “Zeus is the #1 botnet, with 3.6 million PCs infected in the US alone (i.e. approximately 1% of the PCs in the US)…Zeus is a financial malware. It infects consumer PCs, waits for them to log onto a list of targeted banks and financial institutions, and then steals their credentials and sends them to a remote server in real time.”

The report further states that on a sample size of 10000 machines, ” installing an anti-virus product and maintaining it up to date reduces the probability to get infected by Zeus by 23%, compared to running without an anti-virus altogether. The effectiveness of an up to date anti virus against Zeus is thus not 100%, not 90%, not even 50% – it’s just 23%.”
