|As noted, unless you reinstalled Windows you may have bits of the infection still lurking around. Please heed the warning and run the suggested programs that JohnW has listed. He is our expert on serious and deep infections and will help you make sure that all is clean with you.|
Please list your antivirus program in case it is one we consider less than optimal.
I recommend running Malwarebytes manually every 2-4 weeks (or more often if you like) to ensure your machine stays clean.
Change banking passwords at least once or twice a year, more often is even better.
You should be logged in as an ordinary user rather than the admin user. This will help reduce the chances of programs installing without you being asked for approval and password.
Shut down, log off, or put to sleep the computer when you are not going to be using it.
Make sure there is a router between you and the internet. Unplug the modem or router/modem every couple of months to change your external IP address.
If using Wifi, make sure that your Wifi is secure with a log in required. Disable any 'Guest' Wifi account on your router.
Make sure that your browser does not save your banking password so you have to manually enter it every time. Even log in name should be entered every time for banking.
You have to be a little bit crazy to keep you from going insane.
