I think I picked up a virus from a USB drive. Yesterday, my computer automatically downloaded Internet Explorer, which raised my suspicions. Today, when I turned it on, my antivirus quarantined a virus called Trojan: Win32/Suweezy. What steps should I take next?

You should check your antivirus for the exact location of the virus. Sometimes it lists affected files, but if another antivirus found it in the system32 folder, that's a big deal. Stay cautious about that!
If you have important files that aren't backed up, be very careful about how you try to recover them. You can boot into safe mode to access your files without spreading the virus further. Just make sure your USB is clean before you connect it!
First off, it's really important to reinstall Windows using a USB stick, especially if you're worried about the virus. After that, change all your passwords, set up two-factor authentication, and make sure to remove any unknown devices linked to your accounts. Don’t forget to log out of all sessions too!
