Yes. I can confirm that analytics tools can use this IP in Avast. In the case of AvEmUpdate- it is used to obtain information about delivered and applied micro-updates.
If you look at these Geo database websites https://who.is/whois-ip/ip-address/34.149.149.62 and https://whatismyipaddress.com/ip/34.149.149.62
Google Datacenter and not Halliburton use the IP. (The website you are using to check the IP is probably using an outdated Geo database).
Did you use or was the VPN running in the background while accessing your email? Probably a good idea to use multi-factor authentication with your accounts as well.
