Spyware does what the name suggests - it spys on your activities. The information is sent back to a control server on the Internet, where the criminals can collect it. The aim may be simply to monitor the types of websites you visit so that the types of advertising you see can be tailored to your interests. However, spyware is often more interested in recording passwords or credit card details which can be used for financial fraud or to gain access to your on-line accounts. We can clean up these infections, usually on-site.
