Top Five Free Antivirus/Antispyware Software
Posted May 13, 2009
When it comes to protecting their computer from malicious software, many people turn to free security programs instead of paying for one. Although they save you money, free antivirus/antispyware programs do not provide the same level of protection as a paid security program, and you also sacrificing customer support, which is invaluable if your chosen software is unable to remove an infection. On the other hand, of you have multiple computers in your house, it may not be worth putting a paid security program on them, depending what you use each computer for.
Here are the top five free antivirus/antispyware programs that I have seen in my job as a computer technician. Please note that all these programs are for home use only.
Spyware Doctor Starter Edition
Spyware Doctor Starter Edition is the cut down free edition of Spyware Doctor and is good enough that Google included in their Google pack. Google pack is software that is “specifically selected by Google” for internet use.
Spyware Doctor Starter Edition edition’s database isn’t as packed as it’s paid version and it’s heuristic scanner which detects if anything suspicious is running in the background is also limited. Despite it’s limitations, Spyware Doctor Starter Edition is better than some paid antispyware programs available.
Download Spyware Doctor Starter Edition
Avast Antivirus Home Edition
Avast has a popular free antivirus program that works quite well and is light on system resources. Avast Antivirus Home Edition’s biggest problem is it’s poor user interface which makes trying to adjust it’s settings more awkward than it needs to be. You do need to register Avast Free Antivirus before you can use it.
Download Avast Antivirus Home Edition
AVG Antivirus
I’m reluctant to put AVG on this list as I have seen viruses run right past it, but it is the most common free antivirus program I see installed on peoples computers. AVG has the best user interface out of all the free security programs I have seen and it comes with many, though not very good features you would otherwise only find in paid security programs. AVG’s performance various depending on your computer setup. It may run fine on one and bog down another similar computer. Don’t expect AVG Antivirus to be able to protect your computer as well as paid or even other free security programs but it’s better than nothing and it’s large user base mean you will find plenty of unofficial support.
Spybot Search and Destroy
Spybot Search and Destroy is a basic antispyware program. While it doesn’t match Spyware Doctor Starter Edition in protecting your computer, Spybot Search and Destroy is very light on system resources. I recommend Spybot Search and Destroy if you an have older computer that might have trouble running some of the other security software. Spybot Search and Destroy provides very basic protection but that’s all you’ll need for an old computer.
Download Spybot Search and Destroy
Windows Defender
Windows Defender is a Microsoft security program that is free if you have a legitimate version of Windows. As it’s made by Microsoft, Windows Defender runs well within Windows XP, although it does have issues with other security programs or programs that needs to access advanced system files. I’d recommend Windows defender to those who only use their computer for Emails, internet and other basic tasks. Please note that Windows Defender is already installed on Windows Vista.
Windows Task Bar and Desktop Not Appearing Beceause of an Infection
Posted April 2, 2009
Have you ever had an infection on your computer that stops Windows from fully loading? You get the past the Windows splash screen and all you see is either your fake program which will only let you click the “buy now” button, or if you have somehow been able to block of remove the infection, you just see your Windows background and mouse cursor. In both cases there is no Windows task bar so you can’t do anything in Windows.
Your infection is messing with Windows explorer which is what you need in order to navigate around your computer. You can easily get it running again by holding down the Windows key and pressing R. When the run command appears type explorer.exe and click OK.
This doesn’t solve the problem that explorer isn’t launching when you start your computer so you are going to have to go into the registry. Hold down the Windows key and press R. When the run command appears type regedit and click OK.
Now navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\WinLogon\Shell. You want shell to say explorer.exe so double click shell, type in explorer.exe and click OK. If the shell entry is not there, right click in right hand panel and click New > String Value. Call it shell. Double click shell, type in explorer.exe and click OK
While you are in the registry go to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Run. Everything in here is designed to run before explorer.exe is loaded so look for anything with the name of your rogue program in it, select it and press delete.
Restart your computer and now you can now start removing the infection.

Posted March 20, 2009
FileFix Professional 2009 is the beginning of a new trend in fake security programs.

How I removed W32.Downadup.B/Conficker
Posted January 30, 2009
I have just been infected by W32.Downadup.B - AKA Conficker and have spent all night removing it, so now I am going to share the quick way to remove W32.Downadup.B.
First make sure you are infected with W32.Downadup.B/Conficker. The biggest sign is going into My Computer and double clicking your hard drive. If you get an error message about “RECYCLER\S” then you are infected.
Be on the lookout for the “RECYCLER” folder as W32.Downadup.B/Conficker puts this on any drive on your computer. It is launched when autorun runs and is responsible for installing the infection. If your computer is infected with W32.Downadup.B/Conficker, you cant remove the RECYCLER folder as it is just put straight back on. RECYCLER is in the main directory “[YourDriveLetter]:\RECYCLER” so it is easy to find.
There are alot of sites out there showing you how to manually remove W32.Downadup.B/Conficker. Most of these files have the word [Random] in it meaning it could be anything. Don’t bother trying to manually remove it, it’s time consuming and you could do more harm than good.
To get rid of W32.Downadup.B/Conficker you have to use an antivirus/anti-spyware program, I just don’t see any other way around it. Microsoft recommends using their Malicious Software Removal tool. If you can’t access that link, it’s because W32.Downadup.B/Conficker is blocking it. Even if you were able to download it, W32.Downadup.B/Conficker stops the Malicious Software Removal tool from being executed.
I did have some limited success using Microsoft’s Conficker manual removal instructions.. Surprisingly W32.Downadup.B/Conficker allowed me to view the page however it didn’t allow me to download or even install the patches.
Although I used Spyware Doctor to remove W32.Downadup.B/Conficker, this post applies to all antivirus/anti-spyware programs. Even if you are able to download and purchase an antivirus/anti-spyware program, it is next to useless as Conficker will prevent it from downloading the necessary updates. Beceause of this, get whatever antivirus/anti-spyware program you want from an uninfected friends computer. When you have the program, manually download the updates from a website. Most antivirus/anti-spyware programs allow you to do this.
Now BURN THE ANTIVIRUS/ANTI-SPYWARE TO A CD. I cannot stress this enough. DO NOT USE A PENDRIVE/USB DEVICE. It will be infected as soon as you plug it into your computer. This is how I was infected in the first place.
Once on a CD/DVD, install the program onto your computer, put in your registation details and install the manual updates you downloaded. Now let it do a full scan and say goodbye to W32.Downadup.B/Conficker.
After you have removed W32.Downadup.B/Conficker, be sure to install this Microsoft patch. It prevents hackers from taking over your system using W32.Downadup.B/Conficker. Those of you are uninfected will want to install it anyway for safety.
Good luck.
UPDATE: Conficker B++ & Conficker C has recently been released. This is just Conficker that has been modified with different ways to communicate with hackers. It’s impact on your computer is the same as it’s twin brother. As before don’t bother trying to manually remove it but use Spyware Doctor to remove Conficker B++ and Conficker C instead.
Conficker is scheduled to start doing something on April 1st. No one is exactly sure what it will do the general consensus is that it will connect to a server and get further instructions like download a Trojan.
