Can Your Computer Become Infected With A Virus Via Email
Your computer can become infected with a virus via email, but only if you open attachments within a spam email or click on the links contained in them.
Simply receiving a spam email will not infect your computer. Just mark these as spam or junk and ensure they are deleted. Most email providers will automate this but if any slip through the net, just mark them as spam yourself and dont open them.

When Things Get Nasty
Sometimes there are viruses or pieces of malware that fight back when you try to remove them. To help deal with this, Windows has a sort of extra-strength version of its antivirus scan. To run it, go to Windows Security > Virus & threat protection > Scan options, and select Microsoft Defender Offline scan. After clicking the Scan now button, your computer will restart into a special mode to do a scan. Once its done, your computer will restart again, bringing you back to Windows.
If your computer still shows signs of being infected, some of us here at The Verge recommend the free version of Malwarebytes, which has saved our machines more than a few times.
If your PC is still locked up, or youre suddenly getting notifications that you need to send somebody money to unlock it, it may be time to contact an IT professional.

Should You Back Up Before Running Virus Scans
Backing up your computer before a scan might sound helpful. After all, you don’t want your important documents, videos, photos, etc. to be removed along with the viruses.
While backing up can be useful before a virus scan, be extra careful what you’re backing up. The last thing you want is to save all your computer files in a backup and then erase the viruses, only to have them remain in the backup and return upon a restore!
Unfortunately, unless you know exactly what on your computer is infected, you won’t know what’s safe to back up and what’s better left on your computer for the malware scan.
Something you can do to ensure that your most important files are backed up is to copy just those things to an external hard drive or back them up online, but leave the majority of your files where they are. It’s unlikely that the virus scan alone will corrupt your files anyway.
Another way to look at this is to back up anything you want and then run a virus scan on your computer. Should something be found, take note of which files are infected and then delete or scan the backed up files, too, to ensure that the threats are gone from both the originals and the backups.
