ShieldsUp lets you scan a few different port ranges, including File Sharing ports (to make sure youre not offering direct access to your files) and Common Ports (to check the most commonly used ones). It also lets you check all ports via the All Service Ports scan option. In addition, you can tell it to scan a specific port or range of ports. Additionally, you can evaluate your web browser headers for privacy and tracking issues, and test to see if your PC is susceptible to spam via the Windows Messenger Service, a messaging system built into Windows.
If results show open ports, you can investigate the firewall settings of your router or PC and try to close or secure them.
Belarc Advisor is free for personal use, and scans your PCs hardware, network connections, software, antivirus status, Windows Updates, and Windows security policies for insecure settings and other security vulnerabilities. It generates a report in HTML that you can view in your browser. This report provides details on the scanned items and any detected issues, along with links on how to fix them, but it doesnt automatically fix them for you. Also, the information it reveals is geared more for techies and IT professionals than average home users.
In the beginning of the report, the service shows your overall security status via three scores: Security Benchmark Score, Virus Protection, and Microsoft Security Updates. Click on any of these to see more details.
By scrolling through the report, youll discover details on your hardware specs, user accounts, peripherals, and networking. Youll also find a list of installed software versions, licenses, usage, and a report on missing or insecure Windows Hotfixes.
