Occasionallly, AMON may report an error cleaning or deleting an infected file. This can happen when the file is created in a temporary folder and has since been deleted. To ensure that the infected file has been deleted, we suggest you close the alert window and perform an in-depth system scan with the NOD32 on-demand scanner. This will ensure that your computer is virus-free.

If you receive the following message (or similar) when installing ESET Smart Security or ESET NOD32 Antivirus 3.0; "This installation package could not be opened.

To resolve the problem, manually change the proxy settings in NOD32 back to default using the steps below.

This error occurs when a user tries to decompress (unRar) the .EXE installation file instead of allowing the installer to automatically extract the files. If you have downloaded the NOD32 installation file from ESET's website, please double-click this file to initiate the installation. The install files will be automatically extracted and the wizard will guide you through the installation process.

Unfortunately, most firewalls leak. But Comodo's Firewall is unique in that it passes all known leak tests to ensure the integrity of data entering and exiting your system. Comodo has put our firewall through all kinds of sophisticated tests to ensure our firewall is powerful enough to ward off these attacks with default settings. No other firewall has had to work this hard. Take this test yourself.

Malware writers are increasingly tailoring attacks to specific regions, languages and applications.
