Yes if you pay, in that case the only disadvantage is that it makes your system slower, so cheap/old hardware can become unbearable to work on, specially when it's more than 3 years old.
If you computer it's cheap or old then paying for an antivirus its going to add the constrains of everything working slower than it would without it.
But in any case it's better than free antivirus software in that you are protected, you have a contract so you get that support.
Free antivirus software can work alright for certain scenarios like scanning files and store devices as long as it is up to date.
Now a days Linux is the only Operating System where virus don't exist.
Don't pay for and antivirus, pay for a Service-level agreement.
Web browsing It's another world in respect to viruses or unwanted behaviors
Through social engineering unwanted software gets installed in out PCs every day
Tons of antivirus makes you systems slower
They don't warranty any protection or only protect to certain extent
Tackle the problem from the root.
Adblock for browsing ways of knowing if you system is infected

Web browser is a window to huge bastes amounts of information in the internet, and like in any other human activity in a day to day basis there are unwritten rules of conduct, Just as if you walk down the street you don't go shouting I have a big amount a cash in my pocket or here have my credit card this is my PIN number, in the same manner, when we browse we have to take certain precaution.
See you web browser as an interactive area where that part of your screen is intertwined with another system, not necessarily a computer managed by a user but anything, like a system or server that has been programmed to divert your attention, distract you and put you in a vulnerable situation.
Hence the responsibility that a user using this services undertakes, must assume and be aware of.
Social engineering is the main technique most con artist use to get unwanted software in to our PCs every second of every day.
Browsing has become like pealing an onion, layers and layers of ads trying to deceive you, make you think you need something you don't or even remind you of that thing you wanted or thought you might need.
For what is a Pop-up I recommend reading this post first about pop-ups.
Malicious Pop-up software come normally through web browsing by tricking the user to think it needs to install something he doesn't or in the more legit way when installing some freeware with second party software that tends to add functionally not requested and in most cases not desired by the user.
Quick steps to clean PC from not required software:
Remove unused software, Format (recommended)
Prevention
Training
Recovery methodology
Backup (prevention)
Imaging/Windows rescue
Adblock Add-on to block pop-ups on your web browsing and prevent malware coming in
When there is a Pop-up from some software running on the system it will create a task that can be forced to end in task manager.
Standard process to force kill an application.
Ctrl+Alt+Del; (Task Manager)
Application, End task
In most cases the symptoms of infection can be attenuated just by deleting the software installed, [track it down] and uninstall from the system.
Uninstall Software from windows
Uninstall unwanted applications
This steps should be enough to bring your PC to a working point, if after trying this issues still persist might be due to a [stronger type of virus, hardware issues or system setup]
Once the system is running without any conduit software be aware that some configurations, software installed, and setups might still remain, normally by changing the configurations of the browser setups, adding extension or even changing the code. The only way to get rid of this if by a fresh systems setup, format and reinstalling everything from scratch.
To prevent all the pop-up related to browsing, this is, pages with questionable intentions with all sorts of experimental code trying to find a way in to where the money is I recommend using extension on the web browser like adblock which as its name indicates, block all the ad... there are loads of similar extension around, this one is supported on chrome and firefox. In firefox the app be called adblock add-on.
Lately there are some time of web browser pop up that block the browser and try to deceive the end user in to think that its got a virus, this is specially convincing and frustrating because the windows or tab cannot be close or changed or even worst for some users that when reloading their browse open the last session it would stay on that tab on a loop.
chrome and most browser now a day have they're own task manager for closing a tab when several tabs open, this is an example of what the page will say when trying to close and the type of social engineering they try to use to cheat you in to calling them charging you high rates or any other types of scam.
right clink at the top of the chrome browser bar
And click on task manager, click on the tab you want to end and end process

What is a Pop-up, an area that appears or occurs suddenly,
Differentiate between Internet browser pop-up ad, PUP malware and system Pop-up
Internet browser Pop-up are those that appear in an internet browser windows normally when browsing pages of questionable reputation. they differentiate from the rest because they don't have access to the underlying systems, the PC, but it's the doorway too most of the malicious software to get installed on PCs now a days. so it's very important to browse aware and be conscious of where the mouse clicks, not only that but what is the source of any file we download and the type of file, DO NOT RUN A DOWNLOADED .EXE unless you know what you're doing.
PUP/OpenCandy is normally unwanted or even malicious software running on a PC might come installed by manufacturer or bundled to Freeware or downloaded from unofficial sites, sometimes when clicking on Pop-up ads a lot of PUP is installed on the PC and start doing unwanted things, like diverting traffic trough their services to gain money or add layer on websites while browsing using our browsing personal history records.
Malware, some of the PUP can be considered as Malware and end up under very bad hands, sell information on the black market to steel identity is a possibility that comes to mind.
What is Pop-up ad
What is PUP Optional Conduit OpenCandy?
PUP.Optional.OpenCandy is not a virus, strictly Its software that comes bundled in freeware software, in these sense is fall more under unwanted software applications. These can be malicious software adware or toolbars and They can be hard to remove and extremely annoying. So when installing freeware software or any other software, make sure to read the licence terms.
Differentiate between PUP, Internet browser pop-up ad
A PUP popup Its a software already installed in your PC
Either by the manufacturer or as the definition states, bundled in freeware software
Free software, in the way of applications installed for a purpose
Unintentionally, which can be installed in you system just by browsing and clinking on popups. The ways to trick users are unlimited, like, ask to install flash when running a webapps or say that your computer is running slow and they offer you the key to all your questions and needs you just have to CLICK HERE.
For the PUP the best approach is prevention. Once PUP has come in, it can be weaken even in sometime completely deleted. But the systems integrity, in this case the Operating System will be conditioned for ever, sometimes a whole fresh start is needed, always recommended.
On the browser popups side of things Adblock for Chrome or Firefox is the best solution in my experience.
