Rising PC Doctor 6.0.5.16



Rising PC Doctor, professional and smart security tool to computer users. With its seven key functions of automatic malware analysis, immunization of USB storage devices, ability  to  repair Microsoft Internet Explorer & Windows, Trojan Behavior Detector & Blocker, protection against malicious websites, Internet Explorer protection and Trojan Download blocker, Rising PC Doctor will greatly enhance your protection against malware and cyberthreats.

Trojan Behavior Detector & Blocker
Rising PC Doctor can detect the majority of Trojans and a even great number of other malware upon startup before they can execute their malicious function. This function will significantly increase your protection from cyber threats.

Trojan Download Blocker
After successful infection, many viruses automatically start to download large numbers of Trojans and other malware. The Trojan blocking technology of Rising PC Doctor ensures that even an infected computer will not download any other viruses and stop the spreading of whole families of Trojans.

Automatic Malware Analysis
AT boot, Rising PC Doctor can automatically scan for potentially unknown malware. When permitted by the user, possible malware is automatically transferred to Rising’s Automated Malware Analyzer (RsAMA) for detailed analysis. The user is informed about the result of the analysis and can quickly react to new threats for which conventional protection is not yet available. Analysis metadata collected by the community of Rising users (Rising Cloud Security) will be stored in the Rising Security Database (RsSD), providing up-to-date information about cyber security.

Main Functions:
1. Completely Redesigned Vulnerability Scan. The completely redesigned Vulnerability Scan of Rising PC Doctor can detect vulnerabilities in Microsoft Windows, its security settings and third party software from many manufacturers. With the easy to use interface, even inexperienced users can handle potential vulnerabilities in the operational system and a lot of other major software applications.
2. Strong Ability to Repair Microsoft Internet Explorer & Windows. Rising PC Doctor can fix the Internet Explorer on many computers whose homepage has been changed by malware, which are permanently displaying adware or which are plagued by many other problems. On such computers, Rising PC Doctor can help you to repair the system registry, system settings and the host file.
3. Powerful Process and Startup Management. This function gives you better control over drivers, programs loaded at boot, Active X controls and other important software influencing the operation of your computer.
4. Advanced Tools for Experienced Users. Rising PC Doctor provides additional tools for experienced computer users such as Disk Cleanup, System Startup Management, Service Management, Network Application Management, LSP Repair, File Shredder, and Special Virus Removal Tools which are designed to eliminate only a limited number of viruses.

Other Functions:
1. Spyware Scan & Removal. Rising PC Doctor can detect and completely remove many kinds of especially obnoxious spyware from your computer.
2. Strong Protection against Current Trojans. Rising PC Doctor detects and destroys millions of current Trojans designed to steal valuable user information such as online gaming or online banking accounts.

Privatefirewall 7.0.27.1




Privatefirewall multi-layered endpoint security software protects Windows desktops and servers from malware and unauthorized use. Personal firewall, packet inspection, URL filtering, process monitor, and application/system behavior modeling and anomaly detection components  stop hackers, spyware, viruses and other forms of malware before they can cause damage. Privatefirewall detects, blocks and quarantines activity characteristic of known malware, hacking, phishing and other threat types so that personal computer users and IT managers within small, medium or large organizations can more effectively and proactively protect the environments and private data for which they are responsible. You’ll realize expanded protection and become educated about the nature of activity – trusted and un-trusted – that occurs on your system. An exceptionally simple user interface makes Privatefirewall a breeze to manage. An exceptionally simple user interface makes Privatefirewall a breeze to manage.

Privatefirewall features signature-less, behavior-based anti-malware and desktop defense capabilities comprised of several distinct technology layers designed to block or mitigate the damage caused by intrusion, virus and other malware attacks. Beyond unparalleled personal firewall protection, Privatefirewall includes the following layers of proactive, behavior-based defense technology:
• Application Monitor/Manager
• Registry Monitor
• Process Monitor/Manager
• Email Anomaly Analyzer/Manager
• System Anomaly Analyzer
Privatefirewall also detects malware and intrusions based on behaviors characteristic of unauthorized system use.
Some of these include:
• Attempts to access a protected registry area
• Attempts to access a protected object
• Attempts to Initiate a foreign process
• Attempts to control Windows service
• Attempts to create a DNS request
• Attempts to initiate outgoing TCP traffic

Proactive, Multi-Layered Defense:
• NEW! Complete Windows 7 (RTM) and Vista Support – Certified compatible with all versions of Vista (32 and 64 bit).
• Advanced packet filtering – Proprietary stateful packet inspection technology monitors all communication between the PC and the Internet and detects and blocks all unauthorized traffic. Privatefirewall allows the simple adjustment of security levels (High/Low/Custom) to establish different degrees of security for Internet and Local Network access.
• Ultimate Application Control – Highly configurable Application Control Console enables you to specify which and precisely how applications can access the Internet.
• Process Detection – Prevents viruses, trojans, worms and other malware by tracking all trusted processes and providing alerts when any potentially malicious process attempts to run.
• System Anomaly Detection – System Anomaly Detection Engine baselines normal usage based on system variables such as CPU utilization, thread count, and others.  Normal use patterns of running applications are monitored and alerts are generated as unusual activity is detected.
• Intelligent Tray Alerts – Compact, user-friendly tray alerts provide detailed information regarding security events, offer native web search for convenient investigation, and pre-set intelligent “time-out” responses.
• Stealth Mode – PC is invisible when online and stealth to potential intruders.
• Port Tracking and Reporting – All ports are monitored to prohibit unauthorized scanning and system intrusion. Detailed reports are generated on all port scan and other reconnaissance attempts in addition to instantaneous on-screen alerts.
• Email Anomaly Detection – Privatefirewall mitigates the impact of attacks targeting email clients by tracking the volume and frequency of outbound emails. Privatefirewall alerts you and blocks unacceptable deviations from normal email activity.
Application Control and Firewall Policy Management:
• Monitor all traffic to and from your PC and prevent trusted applications from being “Hi-Jacked” to steal local or network-accessible files.
• The Process Monitor adds an important layer of defense to conventional firewall protection by identifying process-level behavior characteristics of intrusion techniques and malware activity.
• Control which applications can access the Internet, and whether to permit/block every application with each usage or make permissions permanent. Specific IPs and/or Websites can be blocked or allowed access.
• Define application specific or global packet filtering rules that can be applied to incoming, outgoing or bi-directional traffic.
• View or create advanced firewall reports sorted by Web, Mail, or System access attempts spanning Hours, Days, Weeks, or customized time periods.

Unmatched Ease of Use:
• Privatefirewall’s security presets deliver superior PC protection immediately upon installation. Setup and configuration are fully automatic right out of the box.
• One-click configuration of pre-defined security settings for Home, Office, and Remote profiles eliminate complicated application tuning.
• Privatefirewall conveniently detects connections to local networks and automatically sets rules that allow access within that network.
• A variety of custom configuration interfaces are easily accessible for advanced users.
• Privatefirewall is fully integrated with Windows XP Security Center.
