move your coins somewhere more secure.
at this time, I do not have access to my BTC. It is still showing as unconfirmed because of "low fee" but my balance is now zero. The BTC is somewhere in lalah land. Will the transaction fail and I will have access to my BTC again?
OK. So for a small regular TX fee you can get your bitcoins fairly easily out of that electrum wallet (and the computer).
1. Change the fees to be set to being fairly high (enough to confirm, using the dynamic fees option - just in case this is required - it does not alter transactions already sent).
2. Download a mobile wallet (if your coins are stored on a PC).
3. Make a backup of said mobile wallet (not necessary but recommended, if possible with a blank sd card that you can remove and store somewhere).
4. Go to electrum and select the "addresses" tab.
5. Select the addresses with money in them and right click them, select "private key", enter your password, click the QR code icon.
6. On your phone app, select sweep papwer wallet (or something that says sweep in the menu tab) and scan the QR code that is on your screen (Don't share this private key though).
7. Repeat this for all addresses.
It may be useful to do this before an antivirus scan as some of them have a tendency to delete electrum and the corrosponding files (and if you have a lot of viruses it'll be difficult to locate the electrum instance to recover those files - but you can copy the electrum data file).
Another note, don't share your private keys as that gives anyone access to your BTC.
