Fake Microsoft or other Tech Support pop up

I have customers that keep getting fake tech support pop up adds that hijack the browser.
These can be from Microsoft, Norton, Comcast, etc.
Is there a program that is effective at blocking these hijacks and not break
the bank?  Free ones are always good, but don't like the upgrades they try to get you to
do.  So if there is a good paid program, I think they would like it being add free.
Thanks.

If you use the Google Chrome browser, use the UBlock (Origin) extension... I found it to be the most effective...

a quick way to determine if the computer has been hijacked or just the browser. on Windows, if you close all browser windows, will you see any new popups?

if I can find a software program that will block, then that is the best route.

Another thing to add is a program called unchecky...    
https://unchecky.com/

It unchecks most add-ins when installing freeware...

If they are getting these popups it is quite possible they are already infected.

Run Adwcleaner  http://www.bleepingcomputer.com/download/adwcleaner/ or preferabley MalwareBytes  https://www.malwarebytes.com/ over the system.

In addition to scanning with malwarebytes to remove malware,
I recommend that you take a 30 day trial of http://www.surfright.nl/en/hitmanpro

When you have cleaned out all the malware, install this really excellent free product
https://www.foolishit.com/cryptoprevent-malware-prevention/
Better still, pay the $15 for the self-updating version.
The $15 is a once-off payment - (no annual or upgrade fees).

Also, make sure that your users don't normally run their PC with admin rights.

If on Windows, can give EMET a try which is from Microsoft themselves that is on look out for exploitation attempt. Another is MalwareBytes Anti-Exploit which specifically oversight tampers or attempt to install malicious browser adds-on. Alternatively, Spybot will be the proxy of the machine - meaning all traffic to the Internet is to go through its inspection. It checks for malicious websites and cookies. Minimally, the extension or pop up through drive by download can be reduced. Application whitelisting is also the layered protection to allow only authorised software and Windows has applocker - Cryptoprevent and SecureAplus are in the same scope of this oversight .

There is no fool proof as there are known evasive means to bypass the defences and the worst are zero days which exploit kit uses at time - but that will be very a targeted attack. Keep your software (like Office, player and browser etc) patched readily - do not ignore the regular update and AV (and other security) scan ..

The browser can be hijacked, and the above advice can solve the problem.
I prefer Malwarebytes and Superantispyware, also CCleaner to clean browser caches and history.
http://mywot.com (installed in each browser) has been effective for many of my clients.
The source of the popup can be a bad website, an infected website, and infected ads on websites.

Adblockers are the first line of defense now.  n2fc suggested one.  Adblock plus allows "acceptable" ads.  The ad networks are just shooting themselves in the foot by allowing malicious ads on them.

Follow it with any of the free a AntiVirus scanners.  Just do that, and much of your problems will go away.

If you don't want to install adblock plus, turn off scripting.
