Computer Security – Time to Think About It

Here we are getting ready for the holiday season, once again. For many of us it’s a wonderful time of the year, full of memories of previous Christmases, and great anticipation for all the good things to come.

During the last holiday season, like many of you, I took the opportunity to get together with family and friends. As so often happens on these occasions, I got quizzed on everyones, it seems to me, least favorite computer related topic; the state of computer security.

These informal “question and answer” gabfests are important to me, since they are a good way to stay in the loop of real world computing experienced by typical users, and not just the esoteric world of the typical “geeky” user.

At that time, some intriguing statistics had just been released from a survey which had been developed by the National Cyber Security Alliance, and security firm McAfee.

The overriding conclusion from the survey was: typical computer users are in need of a “reality check” when it comes to home computer security. Based on my own experiences, I believe this survey does not overstate the case and in fact, additional studies done in the last few months of this year seem to indicate the “security knowledge gap”, continues to widen.

The McAfee/NCSA study found that while 98 percent of computer users agree that having up-to-date security software is important for system security, a significant number of the survey respondents had computers with security software that was incomplete, or dangerously out of date.

Highlights of the survey:

Ninety-two percent of those surveyed believed their anti-virus software was up to date, but in fact, only 51 % had updated their anti-virus software within the previous week.

Seventy-three percent of those surveyed believed they had a firewall installed and enabled, yet only 64 % actually did.

Approximately 70 % of PC users believed they had anti-spyware software, but only 55 % actually had it installed.

Twenty five percent of survey participants believed they had anti-phishing software, but only 12 % actually had the software.

Where do you fit in all this?

Most of us now store a large volume of confidential personal information on our home computers, including information concerning our personal finances, taxes, health, and perhaps personal documentation of other types.

So, it may well be that we need to take the time to survey our computers to insure that all relevant security applications have been installed, are up to date, and are operating correctly.

One of the better applications that will produce a survey of your computer is Belarc Advisor which can be reviewed and downloaded, if you choose, from this Blog. As well, consider downloading and installing Secunia Personal Software Inspector (PSI) which constantly monitors your system for insecure software installations, and notifies you when an insecure application is installed.

If you need to update, or add, additional security applications to your computer, then checkout The Best Free Spyware, Virus and Browser Protection, on this site for reviews and free security application downloads.

Why Are Geeks and Techies So Arrogant?

antivirus.jpgIt has been my experience that Geeks, Techies and computer industry pundits have a tendency to be arrogant and contemptuous of others who do not posses the level of technical understanding that they suppose themselves to have. 

This trait of course is not restricted to those involved in computer technology. I’ve met more than a few auto mechanics who were as arrogant as any arrogant computer Techie I’ve come into contact with. 

It seems to me however, that in the computer industry it is epidemic; from low level consumer oriented technical support at some of the popular retail chains, to software developers who choose to forget that the Computer World/Internet is populated by average users who generally lack sophisticated skills. 

This arrogance is counterintuitive to a new trend in system and Internet security; people driven security. A trend that is exemplified by WOT, (Web of Trust) an Internet community whose purpose is to allow its members to exchange their personal knowledge about a web site’s trustworthiness, vendor reliability, privacy, and child safety by way of an Internet Browser add-on. It seems that people driven security without arrogance has arrived.

I never fail to be amazed when I read the barrage of techno language and techno babblespeak aimed at that mythical computer user who, in reality, doesn’t exist. The computer industry needs to come to an understanding that there is a substantial knowledge gap that exists in the real world of computing? 

Recently I read an article by Larry Dignan, Editor in Chief of ZDNet, in which he described the continuing debate surrounding the viability of the anti-virus industry. It seems at some senior levels of the industry, it is a commonly held belief that anti-virus software is virtually worthless since it cannot keep up with rapidly evolving threats. The proposed solution then is the elimination of anti-virus software. 

In my view this is an arrogant and condescending approach to a real world problem, a real world inhabited by real people, and not just by Techies who are familiar with all of the issues surrounding system security. This is the type of pseudo advice that could lead to chaotic consequences for a typical user. 

Fact: Typical users simply don’t know how to protect themselves adequately. 

The reality is, the majority of computer users are undereducated when it comes to the dangers and threats that the Internet poses to their machines, and to their personal privacy. 

Anti-virus applications are designed to help average users; not the technically sophisticated. So, of course there is a need for them. 

I have a computer sophisticated Internet friend, one who teaches University level Computer Sciences, who frequently reminds me “Too much security is still not enough”. Sadly, he is right. 

I find most tech people (remember I am one), can’t see past the end of their nose when it becomes necessary to look at the broader picture. For example, it would be helpful to develop a view that encompasses the various degrees of computer competency that exists.

The following comment, from one of the forums I participate in sums it up nicely, “Until folks stop trying to exploit/cripple/destroy others, we will need anti-virus software as part of the mix of security solutions. To those who think not … try a virus … you’ll change your mind.”

My Computer Has a Virus – Now What?

 

computer_virus.jpgYou may, or you may not, have a virus so don’t panic. Following the steps below will, in most cases, remove the infection from your system, if in fact your system has a virus. But first, let’s start with the definition of a computer virus so that you know what you’re up against.

A virus is a computer program that can copy itself and infect a computer operating system without permission, or the knowledge of the user. The original virus may modify the copies, or the copies may modify themselves, making the virus more difficult to find.

Not all symptoms that mimic those of a virus infection are in fact produced by a virus. However, if your computer begins to act strangely, or if it is unable to do things it has always done in the past, it may be infected with a virus.

Symptoms including longer-than-normal program load times, unpredictable program behavior, inexplicable changes in file sizes, inability to boot, may indicate that a virus is on your system. However, it is important to distinguish between virus symptoms and those that come from corrupted system files, which can look very similar.

Rule out more standard causes before suspecting a virus. In some cases software related problems, such as program execution errors and corrupted files, can create symptoms that appear to be virus-related. If you just installed new software for example, try uninstalling it and see if the problems disappear.

However, if you regularly engage in any of the following activities, you have substantially increased the risk of your system problem being a computer virus.

  • You download files and software through file-sharing applications such as BitTorrent, eDonkey, KaZaA and other such programs.
  • You click links in instant messaging (IM) that have no context or are composed of only general text.
  • You downloading executable software from web sites without ensuring that the site is reputable.
  • Using your USB stick on public computers, or other computers that are used by more than one person.
  • Opening email attachments from people you don’t know.
  • You make a practice of opening email attachments without first scanning them for viruses.
  • You open email attachments that end in a file extension of .exe, .vbs, or .lnk.
  • You run your Windows computer as an administrator.

 

Next Steps:

Launch Task Manager by hitting Ctrl-Alt-Delete which will give you a list of all current running process. Be aware however, that some viruses are smart enough to bypass Task Manager.

A better solution here would be to use the free service, ProcessScanner, from ProcessLibrary.com, (a Microsoft Gold Certified Partner), which not only scans your Windows computer for all running processes, but in addition tells you what’s running, what each process is associated with, and most importantly, a risk analysis of each process. You may find the answer to the problem here. If not, then proceed to the next step.

In Windows XP, open the Control Panel, Administrative Tools, Services, which will give you a detailed description of the services Windows is running. If you find something that’s unfamiliar, or causes you concern, Google that service/services on the Internet.

Proceed then to select Run from the Start Menu, and type “msconfig” in the box. With this tool you not only see the services running, but most importantly, the programs that your system is launching at startup. Again, if you find something that’s unfamiliar, or causes you concern, Google it on the Internet.

There are a number of online virus scanners that are, in my view, better at detecting malware than locally installed applications. I recommend that you next scan your machine at Trend Micro Online Scanner, and in addition scan it again at Panda Online Scanner. In this situation two is definitely better than one.

Most cases of infection and compromise should be cleaned, and your machine returned to its previous condition, by employing the above methods. But unfortunately, this is not always the case and you’re then faced with performing a full reinstall of the operating system. Since there is always the risk of an un-repairable system, this reinforces the need to ensure you have a realistic backup policy in place.

Security risks on the Internet you need to be aware of.

Trojan horse programs

Back door and remote administration programs

Denial of service

Being an intermediary for another attack

Unprotected Windows shares

Mobile code (Java, JavaScript, and ActiveX)

Cross-site scripting

Email spoofing

Email-borne viruses

Hidden file extensions

Chat clients

Packet sniffing

Security Checklist: Actions you can take to protect your computer system.

Don’t open unknown email attachments

Don’t run programs of unknown origin

Disable hidden filename extensions

Keep all applications (including your operating system) patched

Turn off your computer or disconnect from the network when not in use

Disable Java, JavaScript, and ActiveX if possible

Disable scripting features in email programs

Make regular backups of critical data

Make a boot disk in case your computer is damaged or compromised

Turn off file and printer sharing on the computer.

Install a personal firewall on the computer.

Install anti-virus and anti-spyware software and ensure it is configured to automatically update when you are connected to the Internet.

Ensure the anti-virus software scans all e-mail attachments.

Be proactive when it comes to your computer’s security; make sure you have adequate software based protection to reduce the chances that your machine will become infected.

The free software listed below, in my view, provides better than average malware protection.

avast! 4 Home Edition

www.avast.com

This anti virus app is a real fighter, scanning files on demand and on access, including email attachments. Let’s you know when it detects mal-ware through its shield function. An important feature is a boot-time scan option which removes mal-ware that can’t be removed any other way.

AVG Anti-Virus Free Edition

www.free.grisoft.com

Similarly, this program scans files on access, on demand, and on schedule. Scans email; incoming and outgoing. For those on Vista, your in luck, it’s Vista-ready. I have been using this application since its release and it now forms part of my front line defenses. I recommend this one highly.

SpyCatcher Express

www.tenebril.com

SpyCatcher does a good job of cleaning out spy-ware and at stopping further infestation. In my view however, it’s not as reliable as AVG Anti-Spyware.

Ad-Aware 2007

www.lavasoftusa.com

In my view, Ad-Aware 2007 Free is the best free spyware and adware remover available. It does a relatively good job of protecting against known data-mining, Trojans, dialers, malware, browser hijackers and tracking components. The only downside with the free version; real-time protection is not included.

ThreatFire 3

www.threatfire.com

ThreatFire 3 blocks mal-ware, including zero-day threats, by analyzing program behavior and it does a stellar job. Again, this is one of the security applications that forms part of my front line defenses. I have found it to have high success rate at blocking mal-ware based on analysis of behavior. Highly recommend this one!

Comodo Firewall Pro

www.comodogroup.com

The definitive free firewall, Comodo Firewall protects your system by defeating hackers and restricting unauthorized programs from accessing the Internet. I have been using this application for 6 months and I continue to feel very secure. It resists being forcibly terminated and it works as well, or better, than any firewall I’ve paid for. This is one I highly recommend. Amazing that it’s free!

ZoneAlarm

www.zonelabs.com

The free version of ZoneAlarm lacks the features of ZoneAlarm Pro’s firewall. Its program control asks you regularly whether to allow programs; for some this can get to be intrusive and annoying. But it’s been around forever it seems, and it can’t be shut down, or out, by mal-ware.

WinPatrol

www.winpatrol.com

Do you want to get a better understanding of what programs are being added to your computer? Then WinPatrol is the program for you. With WinPatrol, in your system tray, you can monitor system areas that are often changed by malicious programs. You can monitor your startup programs and services, cookies and current tasks. Should you need to, WinPatrol allows you to terminate processes and enable, or disable, startup programs. There are additional features that make WinPatrol a very powerful addition to your security applications.

Sandboxie

www.sandboxie.com

Surfing the Internet without using Sandboxie is, to me, like jumping out of an airplane without a parachute. Deadly! This application creates a “Sandboxed” protected environment on your machine within which you browse the net. Data that is written to your hard drive is simply eliminated, (or not, your choice), when the sandbox is closed. Utilizing this application allows you to surf the web without the risk of infecting your system with mal-ware or other nasties. This is another security application I have been using for over 6 months and it has yet to let me down. Highly recommended.

Snoop Free Privacy Shield

www.snoopfree.com

Snoop Free Privacy Shield is a powerful application that guards your keyboard, screen and open windows from all spy software. I have been using this application for quite some time, and I have been amazed at the number of programs that have requested access to my keyboard and screen. Particularly, programs that I am in the process of installing. If you’re serious about privacy, this is a must have addition to your security toolbox.

Computer Security – How Aware Are You?

As often happens on these occasions, I got quizzed on everyone’s, it seems to me, least favorite computer related topic; the state of computer security.
