Like the others say, there's no need to go cold turkey Linux...use the dual boot method until you get the hang of Linux.
I've several like that, and use Linux exclusively for Internet work...not viruses that way.
There are still tricks and misleading junk that you must watch out for on the Internet.
Help defray a lot of that with these mods' for Firefox: https://answersrip.com/question/index?qid=20121212075149AACJ9PY
I use Windows for in-house creative work & light gaming only.
Here's how to dual boot: http://www.psychocats.net/ubuntu/installing

Configuring Ubii to look and 'feel' more like Windows...
Ubii behaves much like Windows in some functions, one of which is the "right mouse click", which gives a pop menu indicating choices of what can be done with the item your cursor is over.
One of the first things you can do is put the top 'bar' (called a 'panel' in Linux) down on the screen bottom.
The empty 'stock' bottom panel can be omitted for beginners: Right click panel> click "Delete this panel".
Back to the stock main panel: Right click panel> Properties> General tab> Orientation drop menu> tick "Bottom"> Close.
(Note this window has other options for the look and behavior for the panel.)
Corresponding to Windows 'Control Panel' is the "Control Center".
To display on panel topic "System": System> Preferences> Main Menu> left panel, "System"> check Control Panel.
On the main panel> System, and either "Administration", or "Preferences"; and what is displayed there can be modified for quicker access to specific 'topics' you access frequently.
To modify what's displayed within the 2 'sections' do this:
Panel> System> Preferences> Main menu:
On the left are the "Menu" headings (Applications & System). Click to expand the heading.
Under "System> Preferences" you may want to have checked "Appearance" (for changing the 'look' of Ubii desktop); "Cursor" (choices); "Display" (for monitor); "Main menu" (brings you back to this Display mod section); "Mouse" (behavior); "Network connections" (control how you get "connected"); "Screen saver"; and "Startup applications" (what gets running right away).
Other items not mentioned can be selected as you like, but in general they are relevant to specific items. Feel free to display them, and at your leisure 'open' them to see what the topic is, does, and if you would need quick access to it.
As you become familiar with Ubii, you may want to explore these powerful tools.
Available software installations (beyond the default) are found in the panel "Applications"> Ubuntu software Center> category is by icon, and within that are the various specific items.
Linux is not completely immune to malicious junk, and updates do come along.
Make sure to keep up with those, with a 'Notify' setting; then install when convenient.
Gone will be the days of virus scans and file maintenance: no defragmenting for instance.
Hardware failures are always possible, so get a backup system up and running.
I use "DejaDup"; from the Applications> Ubuntu Software Center. Super simple operation.
