If you know me, you know that I swear by Malwarebytes. I use it on all computers – Mac or PC for initial clean up and to get rid of obvious malware. One of the categories of items that Malwarebytes finds and deletes is what they call PUP files, or potentially unwanted program files.

What are these files and why am I mentioning them? These are programs that you probably don’t want and did not download and install on purpose. You might have clicked on the wrong thing or didn’t see a checkbox when doing another download but now you have this new “junk” on your computer, and you don’t know how to get rid of it or even how it got there.

There are many different programs that fall into this category. A few I have dealt with are OneLaunch, Wave Browser and Shift Browser.

This is why I always tell people to make sure they know what is installed on their computers. If you see any of these icons on your desktop, get rid of these programs immediately!

These all work the same. They take over and become your default browser. They try to look similar to either Chrome or Edge hoping you won’t notice. What they really do is force you to use their search engine to build up their numbers and force you to go to websites you wouldn’t normally go to. I saw a customer just yesterday and he told me that Edge opens up every time he logs into his computer. He demonstrated this for me, and it turns out it was Wave not Edge. Since the colors were similar, he didn’t notice. Once we uninstalled Wave, he didn’t have a browser pop open each time he logged in.

I have seen these redirect you from a real site to a fake site. As I said before, I don’t know exactly how they get installed, but I know it isn’t from people going out and looking for them. If you see these on your computer, you should immediately uninstall them and make sure your preferred browser is set up as your default and your preferred search engine is also your default.

If you are not sure how to uninstall these, or you just need help identifying if you have these or similar “pup” files on your computer let me know and I can help get rid of them. It will probably improve your computer speed.

I often get questions from customers about how to cut down on the flood of unwanted emails they receive every day. Many hope there’s a magic button to stop it but unfortunately, it’s not that simple.

The right approach depends on the type of email you’re dealing with. Here’s a quick guide to the most common kinds of messages and how to handle them:

1. Legitimate Companies (Retailers, Restaurants, etc.)

These are emails that clearly come from a business you recognize, such as “sales@target.com” or “marketing@tacobell.com”. By law, these companies must include an unsubscribe link. Using that link is safe, and within 7–10 days you should stop receiving their promotions.

2. Affiliate Marketers and “Deal” Sites

These come from sketchier addresses like “jayne@yourbestdealsnow.com”. Technically, they’re supposed to follow the same unsubscribe rules—but often don’t. Be cautious: some “unsubscribe” links simply redirect you to more ads. Before clicking, hover over the link to see where it actually goes. A safer option is to use your email provider’s block or report button. This often pushes future emails straight to spam and, in some cases, can even get the sender shut down.

3. Fake or Spoofed Emails

These are the trickiest—and most dangerous. Examples include fake purchase receipts, antivirus subscriptions, or alerts from banks you don’t even use. These messages often come from throwaway or stolen email addresses. Never click “unsubscribe” on these. Doing so could add malware to your computer and tell scammers your email is active, which will only get you more junk. Instead, delete them or mark them as spam.

This list isn’t exhaustive, but it covers the majority of junk mail you’ll run into. If you’re ever unsure, you can forward a suspicious email to me, and I’ll verify whether it’s real.

For small businesses, I also offer tools that automatically block scams and spoofed emails before they ever hit your employees’ inboxes. In the past year alone, my system has stopped nearly 1,000 scam emails for my customers. It’s affordable protection that could save your business thousands in lost time and money.
