All good points for being safer thanks!
I have a windows 7 pc that I am using now for the last 2 months, before that I was always ubuntu. What is a good malware checker that I can try to use just to be 100% certain. I only started using this computer because I need to use photoshop and some other programs that only work on windows.
I'll be safer with the blockchain account and do the usb pen thing, good idea.
Malwarebytes is free forever, I have the upgraded version, still good though
https://www.malwarebytes.org/For a free Antivirus scanner just a 30 day trial
http://www.eset.com/us/free-trial/ but will do the job scanning the system, you can have both scanners running at the same time.
