AVG Internet Security causes the host to go offline

AVG detects LogMeIn Central as a Trojan

For a short period of time, LogMeIn Central was falsely being detected by AVG's Virus Scanner as a Trojan horse virus named Vundo JI. AVG has since issued an update where LogMeIn Central is no longer detected as a virus.

If you quarantined the LogMeIn Central file, you can simply take it out of the Virus Vault to restore functionality:

To restore files from virus vault proceed as follows:

Open AVG.
Go to History.
Go to the Virus Vault.
Select logmein.exe, right-click it and select Restore.

If you completely deleted LogMeIn Central when it was detected, you can restore the host service by reinstalling it. To reinstall LogMeIn Central, please select the link below to download the host installer:

https://secure.logmein.com/logmein.msi

This will pull down the installer for LogMeIn Central. When prompted, select the option to reinstall LogMeIn Central. This will repair and replace any files that were removed by AVG.

To prevent this from re-occurring, please make sure that you update AVG to the latest version, which was released this morning. To update, open AVG and go to Tools > Advanced Settings > Exceptions on the left, add C:\Program Data\LogMeIn as an exception, and restart the host.

Resolve an IP mismatch

This issue is usually caused by connecting to the Internet while behind an Internet load balancer or reverse proxy (satellite).

To resolve, please perform the following steps from the host computer:

Select the following link: http://lmine.ws/t13uB7.
Copy the information in the link and save it in Notepad on the host computer as IP Mismatch.txt.
Rename the file: IPMismatch.reg
Double-click the file to attach the file to the registry.

Change the proxy settings in LogMeIn Central

You can change the proxy settings in LogMeIn Control Panel.

Select the host system tray icon and select LogMeIn Control Panel.
Select Options > Preferences > Advanced tab.
Under Proxy Settings enter the Proxy server address & port. For computers behind a Microsoft ISA server, you need to use the IP address, not the hostname.

Tip: You can find your proxy settings in Internet Explorer under Tools > Internet Options > Network > LAN Settings.

Configure the Client desktop app to use a proxy

You may have to configure the Client desktop app to use a proxy.

Note: This feature is available on Windows only.

Select View from the menu, and select Options from the View drop-down.
Select the Proxy tab.
Check the Use proxy server to connect to the Internet box.
Select Get proxy settings and then select Test proxy settings.
If the proxy test succeeds, select OK.
If the proxy test fails, please enter your proxy information and authentication credentials manually, and then select OK.

Bandwidth requirements for using LogMeIn Central

Remote control performance depends on several factors, such as screen resolution, color depth, type of activity, available bandwidth and latency.

For connecting and doing non-remote control work, any always-on internet connection is sufficient.
For remote control, we require 1.5 Mbit/s (192 Kbyte/s) or higher connection speed on each end, as per FCC guidelines for video streaming. For optimal experience in Full HD resolution, a 2 Mbit/s (256 Kbyte/s) connection is recommended.

The following values are valid for light office work in Full HD resolution (1920x1080 pixels), using a single monitor.

Media streaming, drag and drop file copy and remote printing of large documents require additional bandwidth to retain remote control quality.
Higher latency (above 40ms) reduces the responsiveness of the session regardless of connection speed. Mobile and microwave generally feature higher round-trip times compared to wired and WiFi connections.
Actual bandwidth usage may be lower than indicated, depending on your activity.

Tip: If you are unsure of your connection speed and latency (ping), or just want to check, please go to http://speedtest.net, and run a speed test. The result is given in Mbps (Mbit/s).

Color quality	Mbit/s	Kbyte/s
Compressed (JPEG)	3	400
High	4	500
HD	2	256

Sound quality	Kbyte/s
Low	4
Medium	8
High	16

About working with dynamic IP addresses in LogMeIn Central

GoTo does support dynamic IP addresses.

Our software is coded in a way that does not require the IP address to be known prior to connection. Remotely Anywhere, however, requires a static IP address.
