Hey these are good advices for newbies, recently many users fell for the Electrum wallet scam, where the PC version asked them to update it, many didnt even realise they were being scammed. I feel if you need to update only visit the official site, and update it from there. It seems you missed one important tip, never do any transactions on a public and unsecured network, 99% chances are your data will be hacked.
