Microsoft Defender mistakenly flagged legitimate DigiCert root certificates as Trojan:Win32/Cerdigent.A!dha, leading to their removal from Windows systems globally. This issue arose after a Defender signature update on April 30th, with affected certificates including 0563B8630D62D75ABBC8AB1E4BDFB5A899B24D43 and DDFB16CD4931C973A2037D3FC83A4D7D775D05E4. The certificates were removed from the AuthRoot store under the Registry key HKLMSOFTWAREMicrosoftSystemCertificatesAuthRootCertificates. Microsoft has addressed the issue in Security Intelligence update version 1.449.430.0, which also restored the removed certificates. The false positives were linked to detections related to a recent DigiCert breach, where threat actors obtained valid code-signing certificates used for signing malware. DigiCert revoked 60 code-signing certificates, including those linked to the "Zhong Stealer" malware campaign. The malware utilized certificates issued to companies like Lenovo and Kingston, but the certificates flagged by Microsoft Defender are root certificates and do not correspond to the revoked code-signing certificates.

Securing all devices with antivirus protection is essential, and while free options can provide adequate defense, Microsoft claims that Microsoft Defender Antivirus is sufficient as the sole line of defense for Windows. Microsoft Defender has evolved since its inception in 1993, but historically it struggled against independent antivirus solutions. Microsoft argues that its telemetry is a better measure of effectiveness than lab scores, highlighting Defender's capabilities against running files, unsafe links, and unauthorized changes. However, it acknowledges that users with multiple devices may need third-party solutions, as Defender does not support non-Windows devices. Defender's phishing protection is limited to the Edge browser, and it lacks many features standard in other free antivirus solutions, such as dark web monitoring and VPN protection. Additionally, it does not utilize Windows Copilot for scam detection, leaving users vulnerable. Its user interface is also considered less intuitive compared to competitors. While Defender offers basic protection, it is not comprehensive enough for most users, who may benefit from exploring third-party antivirus options for enhanced security.

Antivirus software protects against various sophisticated malware threats, including ransomware, spyware, phishing attacks, and adware. When selecting antivirus software, consider the number of devices needing protection, the operating systems in use, and whether the protection is for personal or business purposes. Free antivirus options have improved and may suffice for average users, while paid plans typically offer better protection and support. Evaluating products involves reading privacy policies, utilizing free trials, and checking independent test results. The best antivirus software depends on individual needs, devices, budget, and online behavior.

Microsoft Defender Antivirus, originally launched in 1993 as Microsoft Anti-Virus for MS-DOS, has evolved over the years but historically struggled with effective malware protection. Recent improvements have led to better performance in independent lab tests. Microsoft claims that Defender's built-in capabilities are sufficient for protection against various threats, but it acknowledges that third-party antivirus solutions may be necessary for users with multiple devices. Defender's phishing protection is limited to the Edge browser, and it lacks many features found in competing antivirus products, such as advanced scam protection and a user-friendly interface. While Defender offers basic protection, it may not meet the needs of most users in today's digital landscape.

The message “You’ll need a new app to open this windowsdefender link” indicates issues with the Windows operating system when the Windows Security app fails to launch via the windowsdefender protocol. This can prevent users from accessing the security dashboard, despite Microsoft Defender continuing to operate in the background. Common scenarios leading to this error include clicking on Virus & Threat Protection, trying to open Windows Security from the Start menu, interacting with a Defender notification, or following the uninstallation of third-party antivirus software. Root causes may include corrupted Windows Security app registration, damaged system files, third-party antivirus interference, misconfiguration of the Security Center service, or malware interference. To resolve the issue, users can verify that required services are running, repair system files using SFC and DISM, re-register the Windows Security app, check for third-party antivirus conflicts, and perform a repair installation of Windows. Specific steps include checking the status of the Security Center and Microsoft Defender Antivirus Service, executing repair commands in CMD, re-registering the Windows Security app using PowerShell, uninstalling third-party antivirus software, and performing an in-place upgrade if necessary.

Microsoft has announced that users of Windows 11 do not need additional antivirus software, as Microsoft Defender is built-in and provides sufficient protection against malware, suspicious downloads, and phishing sites. OpenAI has shifted its advertising model for ChatGPT from cost-per-thousand impressions (CPM) to pay-per-click (CPC), allowing advertisers to bid between and per click. Yelp has upgraded its AI-powered assistant to answer inquiries, recommend services, and facilitate bookings through natural language processing, integrating with platforms like Vagaro and Calendly. Google has increased usage limits for subscribers of Google AI Pro and AI Ultra in Google AI Studio, making app creation more accessible and simplifying cost assessments for developers.

The summary shall NOT include a title, introduction and conclusion. Text: Welcome to this week’s edition of The Main Street Tech Report, where we delve into the latest advancements in small business technology. Here are five notable developments in AI, automation, and digital tools that have surfaced recently, along with their implications for your business. Microsoft Officially Says You Don't Need Extra Antivirus on Windows 11 In a recent announcement, Microsoft has clarified that users of Windows 11 do not require additional antivirus software. As reported by PCWorld, Microsoft Defender, the built-in protection software, is touted as “the most secure Windows yet.” This tool is activated by default and consistently updates to guard against malware, suspicious downloads, and phishing sites. While Microsoft acknowledges that users with multiple devices or those needing parental controls might consider supplementary protection, for the majority, the fully updated Windows Defender suffices. Why this is important for your small business: This development may not be welcomed by antivirus software manufacturers, but it underscores a significant shift in how security is approached. It raises the question of why such protection wasn’t integrated into operating systems sooner. For small businesses, collaborating with IT professionals to optimize Microsoft Defender is crucial. Ensuring that operating systems are updated and avoiding unnecessary bloatware from antivirus vendors can streamline security efforts. OpenAI Turns on Cost-Per-Click Ads Inside ChatGPT OpenAI has transitioned its advertising model for ChatGPT from a cost-per-thousand impressions (CPM) to a pay-per-click (CPC) system, as highlighted by Digiday. Advertisers can now bid between and per click, allowing for more direct and measurable engagement results. This change comes after a notable decline in CPM rates, which fell from to as low as since February. Gartner analyst Nicole Greene notes that this shift provides advertisers with consistent metrics to justify reallocating their budgets to OpenAI. Why this is important for your small business: As ChatGPT and similar AI platforms adopt a CPC model, businesses may find themselves navigating a challenging landscape. My own experiences with CPC advertising have often led to discrepancies between reported clicks and actual engagement, leaving many advertisers frustrated. Small businesses should approach these platforms with caution, ensuring they have clear tracking mechanisms in place to evaluate the effectiveness of their ad spend. Yelp Launches AI-Powered Assistant to Streamline Local Search and Bookings Yelp has enhanced its AI-powered assistant, Yelp Assistant, which now goes beyond merely listing businesses. This upgraded tool can answer inquiries, recommend services, and facilitate reservations or appointments through natural language processing. With integrations into platforms like Vagaro, Zodoc, and Calendly, Yelp is evolving from a search engine to a transaction-driven assistant, thereby enhancing the user experience. Why this is important for your small business: While my focus is primarily on B2B technology services, businesses in the B2C sector should take note of Yelp’s new capabilities. Engaging deeply with Yelp’s AI offerings could yield significant benefits, particularly for companies that align well with its audience. Collaborating with Yelp experts may also prove advantageous for those looking to maximize their presence on the platform. Start Vibe coding in AI Studio With Your Google AI Subscription Google has announced that subscribers to Google AI Pro and AI Ultra will enjoy increased usage limits in Google AI Studio, facilitating app creation. This update includes access to Gemini Pro and Nano Banana Pro, simplifying the transition from experimentation to production for developers. Previously, managing API keys and usage charges posed challenges, but the new subscription model allows for better cost assessment before committing to API pricing. Why this is important for your small business: While Claude has garnered attention in the AI space, Google’s advancements in AI Studio position it as a formidable player. As the company continues to roll out innovative tools, small businesses should keep a close watch on developments, particularly with the upcoming Google I/O event on May 19th, which promises to unveil exciting AI innovations. HubSpot Introduces Outcome-Based Pricing for AI Agents Starting April 14 HubSpot has launched an “outcome-based pricing” model for its Breeze Customer Agent and Breeze Prospecting Agent. This approach ties costs to completed tasks rather than just licensing fees. For instance, the cost per resolved conversation has dropped from to [cyberseo_openai model="gpt-4o-mini" prompt="Rewrite a news story for a business publication, in a calm style with creativity and flair based on text below, making sure it reads like human-written text in a natural way.

Here are five key developments in AI, automation, and digital tools that emerged this week-and what they mean for your business.Microsoft Officially Says You Don't Need Extra Antivirus on Windows 11Hans-Christian Dirscherl of PCWorld reports that Microsoft has announced Windows 11 users do not need to add third-party antivirus software. According to the company, Microsoft Defender – Windows 11 built-in protection software – has made it “the most secure Windows yet.” Defender is activated by default and continuously updates to protect against malware, suspicious downloads, and phishing websites. Microsoft suggests for those who run multiple devices or implement parental controls may want to add an extra layer of protection but for most users Windows Defender is enough, providing it’s fully updated. (Source: PCWorld)Why this is important for your small business: I’m sure the makers of anti-virus software aren’t thrilled to hear that news, but wasn’t the writing on the wall? I always wondered why anti-virus and malware protection wasn’t already built into a device’s operating system and turns out it is (and probably always was). My advice is to work with your IT professionals to fully configure Microsoft Defender to provide protection, ensure that your users are upgrading their operating system when required and leave out any additional bloatware from anti-virus software makers.OpenAI Turns on Cost-Per-Click Ads Inside ChatGPTOpenAI has switched its ChatGPT ads to pay-per-click pricing in a significant shift from its previous cost per thousand impressions model, Digiday reports. According to details, advertisers can bid between $3 and $5 per click in the Ads Manager interface. Cost per clicks give advertisers more direct, measurable results for customer engagement in comparison to CPMs. And since February, the rate for CPMs has dropped from $60 to as low as $25, decreasing ad revenue for OpenAI. The benefit for advertisers is CPCs allow them to compare their ad spend on other platforms like Google. Gartner analyst Nicole Greene said, “In a world where everything is changing due to AI tech and consumer behaviors, this consistent measurement will help advertisers justify reallocation of spend to OpenAI.” (Source: Digiday)Why this is important for your small business: Sadly, ChatGPT – and likely other AI platforms – is heading down the same “cost-per-click” black hole that Google prefers. And it really is a black hole. My experience with CPC is frustrating and disappointing: Google tells me an ad got a thousand clicks and yet my landing page shows five people hit it. Why the difference? No one ever answers that question and yet my ad budget is duly depleted. Yelp Launches AI-Powered Assistant to Streamline Local Search and BookingsYelp has made significant upgrades to its AI-powered assistant – Yelp Assistant. Instead of just producing listings, the assistant can answer questions, recommend businesses, and complete actions like reservations or appointments. Users can complete these tasks using natural language with Yelp Assistant that can interpret complex queries and requests.Yelp’s large database of reviews and photos help explain why a specific business fits the request. The system is now integrated with platforms such as Vagaro (beauty/wellness), Zodoc (healthcare appointments), and Calendly. Also new is Menu Vision – a feature that allows users to view menus up-close before ordering. Yelp is evolving from a search/discovery engine to a transaction-powered assistant, making the search experience smoother. (Source: Search Engine Land)Why this is important for your small business: My company sells technology services and software B2B so I’m less inclined to use Yelp. But if I were a B2C company or my business was more attuned to Yelp’s audience I would be diving deeply into the platform’s latest AI offerings and integrations. I would probably be using an outside Yelp expert as well. I’ve worked with other small businesses who have done well reaching prospects on Yelp but only after investing a considerable amount of effort and resources to do so.Start Vibe coding in AI Studio With Your Google AI SubscriptionThis week, Google announced that Google AI Pro and AI Ultra subscribers have “increased usage limits” in Google AI Studio to make app creation more accessible. This includes access to Gemini Pro and Nano Banana Pro, making it easier for developers and hobbyists to transition from experiments to production. Before this update, developers had to manage API (Application Programming Interface) keys, quotas and usage-based charges early in the process. Now developers can more easily assess monthly costs before committing to API pricing through this new subscription model. “These benefits offer an easy entry point to developers who would like to experiment and prototype more deeply with AI Studio,” Google stated. (Source: Google)Why this is important for your small business: Claude has been receiving all the “vibe-coding” attention lately (with a little shared with OpenAI) but my prediction is that Google is going to ultimately be the main player, particularly as it rolls out more tools within their AI Studio to help developers create solutions. Keep a close eye on the upcoming Google I/O event on May 19th where I’m expecting the company to announce many blow-your-mind AI developments.HubSpot Introduces Outcome-Based Pricing for AI Agents Starting April 14HubSpot has introduced “outcome-based pricing” for its Breeze Customer Agent and Breeze Prospecting Agent, offering a more valuable way for businesses to leverage AI. Rather than paying just for licenses, HubSpot’s new model attaches costs to completed tasks. According to the company, the cost per conversation has been reduced to $0.50 from $1 per “resolved conversation” by its Breeze Prospecting Agent. For the Prospecting Agent, the cost is $1 per qualified lead. This move by HubSpot demonstrates an understanding that businesses are looking for measurable ROI that could make adoption easier for those who are more skeptical about AI tools. “Businesses are being asked to make big bets on AI right now… Outcome-based pricing removes that risk,” HubSpot’s Chief Customer Officer, Jon Dick, said. (Source: Small Business Trends)Why this is important for your small business:This is a very interesting way to price a product and one that’s more suitable to companies looking for clear ROI on their technology investments. As a CRM provider, it’s always difficult to quantify the value of what we sell. This type of approach makes it a more tangible discussion.“Have a technology story that small business owners should know about?

Why this is important for your small business: This innovative pricing model offers a tangible way for businesses to assess the value of their technology investments. As a CRM provider, quantifying value can be challenging, but outcome-based pricing fosters a more concrete discussion around ROI.

Microsoft has updated its guidance for over 500 million Windows 11 users, encouraging them to evaluate their security measures. The company asserts that Microsoft Defender, its built-in antivirus software, is adequate for most users, providing protection against potential risks from the moment the PC is powered on. While Microsoft acknowledges that its default protections are usually sufficient, it also notes that the decision to use third-party antivirus solutions depends on individual usage patterns and desired features. Users managing multiple devices, sharing devices with family, or seeking additional services like identity monitoring may consider third-party options. However, Microsoft warns that adding extra security tools can complicate system performance and incur unnecessary costs. The perception of built-in protection has evolved since the Windows XP and Windows 7 eras, with Windows 10 and 11 reinforcing the reliability of Microsoft Defender. Despite this, the guidance is not expected to significantly impact the third-party antivirus market, as testing has shown a variety of excellent options available for users looking to enhance their security.
