Erostars is a program that gets installed by visiting pornographic websites, whether intentionally or by accident. It commonly installs on the PC without user knowledge or consent, and dials toll numbers through your modem to download pornographic content to your computer. These high tolls will get charged to your telephone bill. Removal of Erostars is recommended, as it is a high threat to the security of your PC. It can affect system stability, and gain access to data and private information. It is a virus that requires removal with an antispyware tool such as Spyzooka, which will scan your PC for security threats and once detected, remove them completely so that security is restored.
