UnHack Your Computer

Written by oneself on 6:18 AM


There's nothing new under the sun, and rootkits are no exception. In the early days of personal computers, in the age of the DOS command-line operating system, there were viruses that hid their presence from the users and anti-virus programs. They did it by intercepting some system calls that were responsible for reading the files, and lied to the system by filling these calls with fake information. You could view an infected file right in front of your eyes and see nothing but legit code! These viruses were called 'stealth' in those days.

When computers evolved, Windows replaced the DOS. Old viruses did not run under the new operating system, and it wasn't easy to develop simple hacks to intercept system calls in Windows. But time has passed, and now there's a new wave of viruses that can work on Windows and hide their presence even more efficiently than the stealth viruses of the old days. These new viruses are called rootkits.

Today, using an antivirus does not guarantee complete safety. A rootkit could install into your system and fool the antivirus system by hiding itself. The problem is that modern antivirus programs try to detect rootkits at the time when they are already active. Antivirus programs use the very functions that are intercepted by the rootkits specifically for the purpose of deceiving antivirus. It's a gun vs. armor race and your PC is the firing range.

Microsoft tried to address the problem by releasing their own Rootkit Revealer. While being a correct concept, this tool fails on too many levels. Microsoft Rootkit Revealer is intended for use by system administrators and software developers. The results of its work are not detections but rather hint that there's something in the system that's hidden. And of course, Rootkit Revealer does not remove rootkits, making its benefits questionable at best for a regular computer user.

Complement your antivirus with a rootkit detection and removal system and liberate your PC from rootkits! UnHackMe with Partizan technology is highly compatible and designed to complement other antivirus solutions instead of conflicting with them.

The Partizan technology is unique to UnHackMe. Microsoft states that there exists no sure way to know of a rootkit's presence from within a running system. Instead of trying to combat rootkits on their own ground, Partizan fools them by booting with the operating system and taking control before any rootkits can load. Being the first to load, UnHackMe can safely watch all stages of the Windows boot process, effectively detecting and terminating any activities attempted by the rootkits.

Once there's no rootkit in the computer's memory, detecting and removing one is a matter of routine. UnHackMe can remove known rootkits by itself or simply block the rootkit from loading into memory and pass control to your regular anti-virus.

Scanning your entire PC for the presence of a rootkit with a regular antivirus can take hours of time depending on the number of files and programs you have. UnHackMe takes scanning speed to another level by taking only a few seconds every time your computer loads.

Antivirus and anti-rootkit products often conflict with each other. Not UnHackMe! You can safely pair UnHackMe with an antivirus of your choice, providing ultimate protection against all kinds of viruses and rootkits. Download your evaluation copy now from: http://greatis.com/unhackme/

Top 6 Standalone Spyware Scanners

Written by oneself on 5:07 AM

From Mary Landesman,

It's not just viruses that plague today's Internet users. Spyware surreptitiously monitors your computer and Internet use, while adware can bombard your PC with unwanted advertising. Both pose a drain on your bandwidth and can lead to loss of security. Following are a selection of the best dedicated adware and spyware scanning tools to ferret out these often hidden menaces. If you go the standalone route, make sure you back it up with antivirus software and a firewall.

1. McAfee VirusScan

McAfee AntiSpyware 2006 is no longer sold as a standalone product, but don't despair. McAfee VirusScan (2006) includes the same stellar protection. In our tests, both products nabbed 98% of running processes associated with adware and spyware, effectively neutering the infestation. At $39.99 for both stellar spyware protection and a top-notch virus scanner, McAfee VirusScan (2006) is a steal.

2. Webroot Spy Sweeper

Spy Sweeper removed 100% of the miscreant BHOs and Toolbars in our tests and stopped 84% of the active processes associated with adware and spyware. Spy Sweeper is a standalone spyware scanner and not a full-fledged Internet security suite, thus it is best used in conjunction with antivirus and firewall software.
Compare Prices

3. Sunbelt CounterSpy

Sunbelt's CounterSpy removed 90% of the miscreant Browser Helper Objects (BHOs) in our tests. Sporting above average detection for only $19.99, CounterSpy offers inexpensive protection, an easy-to-use interface and US-based tech support.
Compare Prices

4. Windows Defender

Windows Defender is offered free and, like CounterSpy, sports above average detection rates. The product is still considered beta and tech support is not provided. Despite these setbacks, it can provide a good second opinion. However, Microsoft AntiSpyware and CounterSpy should not be installed on the same system, as they both share common components.

5. Spybot Search & Destroy

Free for personal use, Spybot doesn't have stellar removal rates. It does, however, provide TeaTimer and SDHelper which are extremely effective at preventing adware and spyware from gaining a foothold on your computer. So while you may not want to rely on it for detection and removal, you may want to install and activate it alongside other protection to help keep your system spyware-free.

6. Hijack This

Another free utility, Hijack This isn't a traditional spyware scanner. It will, however, provide a full report of what's active on your system. Experienced users can peruse the report, identify the miscreants, and use Hijack This to disable the unwanted loading (or do so manually). Less experienced users can save the Hijack This log and send it to a more savvy friend for advice.

Free tech support is available via email and the standard license includes two years of protection. Should be used in conjunction with a firewall.

Computer Safety Tips

Written by oneself on 4:21 AM

From Mary Landesman,

Achieving good computer security can seem like a daunting task. Fortunately, following the few simple steps outlined below can provide a good measure of security in very little time.

Use antivirus software and keep it updated. You should check for new definition updates daily. Most antivirus software can be configured to do this automatically.

  • Top Antivirus Software
  • Top Spyware Scanners

    Install security patches. Vulnerabilities in software are constantly being discovered and they don't discriminate by vendor or platform. It's not simply a matter of updating Windows; at least monthly, check for and apply updates for all software you use.

  • For Windows updates, visit the Windows Update Center
  • For all other updates, use the Secunia Software Inspector Firewalls are necessary even if you have a dial-up Internet connection - it takes only minutes for a a non-firewalled computer to be infected.

  • Free ZoneAlarm Firewall
  • Using the Windows Firewall

    Secure your browser. If you use Internet Explorer, you will be able to take advantage of the security zones settings to ensure optimum browsing safety. Not only will you enjoy safer browsing, you'll be able to eliminate unwanted pop-ups as well.

  • Securing Internet Explorer

    Take control of your email. Avoid opening email attachments received unexpectedly - no matter who appears to have sent it. Remember that most worms and trojan-laden spam try to spoof the sender's name. And make sure your email client isn't leaving you open to infection. Reading email in plain text offers important security benefits that more than offset the loss of pretty colored fonts.

  • Why Plain(text) is Better
  • How To Secure Your Email

    Treat IM suspiciously. Instant Messaging is a frequent target of worms and trojans. Treat it just as you would email.

  • Tips for IM Safety

    Avoid P2P and distributed filesharing. Torrent, Kazaa, Gnutella, Morpheus and at least a dozen other filesharing networks exist. Most are free. And all are rife with trojans, viruses, worms, adware, spyware, and every other form of malicious code imaginable. There's no such thing as safe anonymous filesharing. Avoid it like the plague.

    Keep abreast of Internet scams. Criminals think of clever ways to separate you from your hard earned cash. Don't get fooled by emails telling sad stories, or making unsolicited job offers, or promising lotto winnings. Likewise, beware of email masquerading as a security concern from your bank or other eCommerce site.

  • Internet Scams, Phishing, and Fraud

    Don't fall victim to virus hoaxes. Dire sounding email spreading FUD about non-existent threats serve only to spread needless alarm and may even cause you to delete perfectly legitimate files in response.

  • Hoax Encyclopedia
  • Urban Legends and Folklore

    Remember, there's far more good than bad on the Internet. The goal isn't to be paranoid. The goal is to be cautious, aware, and even suspicious. By following the tips above and becoming actively engaged in your own security, you'll not only be protecting yourself, you'll be contributing to the protection and betterment of the Internet as a whole.
