Frequently Asked Questions (FAQ)

Do you need security extensions for your browser?

Google warned of a severe cyber danger to its Chrome browser on March 25, 2022. These "high-vulnerability" threats target software flaws. They make it possible for thieves to access your hard disk and take confidential data.

Google typically doesn't release a single-bug emergency security update. So it seems this one posed a significant threat...

Users of Google Chrome should immediately update to the newest version (99.0.4844.84). You should be secure from this specific threat if your browser is this version or above. (At least until hackers discover another workaround.)

Although it's usually a good idea to keep your Chrome browser updated, it's not always a guarantee that doing so will keep you safe. It is also insufficient to use conventional anti-virus software.

Fortunately, there is a quick and safer solution to safeguard your browser; that is where the security extensions above come in handy.

What are some of the risks associated with not having anti-virus software installed?

Without antivirus protection for your browser, you run the danger of compromising both your entire PC and important data. But what are the exact threats you face? Here are a few examples:

• Identification fraud
• Loss of personal information, including emails, images, etc.
• Hardware malfunction
• Sluggish browser or computer performance
• Frequent freezing or crashing
• File access may be restricted.
• Financial loss as a result of a ransomware attack
• Financial loss brought on by an attack on your internet banking account
• Loss of vital business data

What is the difference between a browser based and traditional antivirus software?

Unlike traditional antivirus programs that allow a threat to enter your computer and THEN take action to remove it, these Browser security extensions block threats BEFORE they have a chance to do any harm.

Will Browser Security Extensions slow down my computer?

Most likely not at all. While earlier computers used to be far less powerful, making this more of a concern, modern machines can easily bear the strain of running antivirus software on your browser without adverse effects on speed. We cherry-picked the leading security extensions that have minimal to no impact on your system resources.
