To view instructions for an operating system other than Windows, choose the appropriate operating system below:
Confirm the hard drive partition (for example, C:\) where your ESET product is installed, has enough free disk space (minimum of 1 GB).
Exclude ESET from detection on your third-party firewall (such as Norton Personal Firewall, ZoneAlarm, or others). If you are using the ESET firewall and have no other firewall software installed, disregard this step.
If you do not use HTTP proxy for downloading updates:
Open the main program window of your Windows ESET product. Press the F5 key to open Advanced setup.
Click Update, expand Profiles → Updates → Connection Options, select Do not use proxy server from the Proxy mode drop-down menu, and then click OK.
Business users only: If your settings in HTTP Proxy are locked (read-only) then this proxy policy was forced by ESET PROTECT, ESET Security Management Center, or ESET Remote Administrator.
ESET PROTECT 9.x: You can revoke this setting from the ESET PROTECT Web Console. If there is no access to ESET PROTECT Server (for example, ESET PROTECT Server no longer exists) Uninstall the ESET PROTECT Agent and then Uninstall and reinstall ESET endpoint products using ESET PROTECT (8.x).
ESMC 7.x: You can revoke this setting from the ESMC Web Console. If there is no access to ESMC Server (for example, ESMC Server no longer exists) Uninstall the ESMC Agent and then Uninstall and reinstall your ESET endpoint product.
ERA 6.x: You can revoke this setting from the ERA Web Console. If there is no access to ERA Server (for example, ERA Server no longer exists) Uninstall the ERA Agent and then Uninstall and reinstall your ESET endpoint product.
Test communications with the ESET update server:
Press the Windows key + R on your keyboard, type
cmd into the text field and press Enter.
Windows 8 users: Press the Windows key + Q on your keyboard to open an app search and type
cmd into the Search field.
ping update.eset.com into the command prompt and press Enter (see Figure 1-1 below).
If you are able to connect to the update server, you will see a Reply from message followed by the IP address of the server you are trying to reach.
