Trojan Removal Procedure.



Malware is a general word for all form of Viruses, Spyware etc. This procedure works for all Malware. Replace the Ewido program with the appropriate program.



You might be unable to access the Internet after removing the Malware so you will need to run LSPfix or Winsockxpfix (as appropriate). Download one and save to desktop, run it later.



LSPfix: all Windows OS except 95.



http://www.cexx.org/lspfix.htm



Winsock XP Fix: Windows XP only.



http://www.spychecker.com/program/winsockxpfix.html







Download and Update Ewido (now called the AVG Antispyware):



http://www.ewido.net/en/download/





-- If you have problems updating see here:



http://www.ewido.net/en/download/updates/



Once the updates are installed do the following:







Let's get cleaning



Part 1



• Temporarily show hidden files.



For Windows XP:



1.

Click Start, and then click Control Panel.



2.

Click Appearance and Themes, and then click Folder Options.



3.

On the View tab, under Hidden files and folders, click "Show hidden files and folders", and clear(uncheck) the "Hide protected operating system files" check box.







For older systems:



1.

Double-click My Computer, click View, and then click Folder Options.



2.

On the View tab, under "Hidden files and folders", click "Show hidden files and folders", and clear (uncheck) the "Hide protected operating system files" check box.





IMPORTANT: Files are hidden by Windows for a very good reason. It is not wise to experiment with these files. Unfortunately, to successfully remove modern spyware we must turn this protection off temporarily. Please turn the protection back on when you have finished cleaning your system.





Empty your Internet Explorer cache and your other temporary file folders:



1.

On the Internet Explorer Tools menu, click Internet Options.



2.

On the General tab, in the Temporary Internet Files section, click the Delete Files button. This will delete all the files that are currently stored in your cache.



3.

Select the Delete all offline content check box in the confirmation dialogue box that appears, click OK.



4.

Click OK again.



Restart in Safe Mode:



To do this you need to hold down or repeatedly tap the F8 key while the computer is booting (when the computer is displaying a black screen with white text). When the boot menu appears, use your keyboard arrows to select "Safe Mode."



Safe Mode can look quite ugly. The color may look bad, and all of your desktop icons will be very large. This is normal.







Start Scan and let Ewido scan the PC





When the scan and removal are completed REBOOT COMPUTER. This will restart you in normal mode.



If you are unable to access the Internet after removing Malware you will need to run LSPfix or Winsockxpfix (as appropriate).





If you are using Windows XP Service Pack 2 (SP2) and are unable to access the Internet after removing Malware, there is a command that may fix the problem, removing the need to run Winsockxpfix. It works by resetting the winsock catalogue. Click on Start, then Run and type CMD in the dialogue box that appears. Click OK. Type "netsh winsock reset" (no quotes)into the DOS window that appears.





The last steps



If you are running Windows XP or Windows ME, and your computer has been successfully cleaned of Malware, there is one more thing that needs to be done.



Delete any old restore points and then create a new restore one. The old ones may, of course, be infected with the Malware and cannot be used.



First, start and then stop the Restore Service. This is done differently depending on what operating system you are running.



Windows XP:



1.

Click Start, and then click Control Panel.



2.

Click Performance and Maintenance, click System, and then click on the System Restore tab.



3.

Select the Turn Off System Restore check box, click Apply, then restart your computer.



4.

Return to the System Restore Tab and turn System Restore back on.





Windows ME:



1.

Click Start, click Control Panel, click System.



2.

Click Performance, click File System, and then click Troubleshooting.



3.

Enable the option Disable System Restore, click Apply then restart your computer.



4.

Return to the Troubleshooting tab and turn System Restore back on.





To set a manual restore point complete the following steps:



1.

Click the Start button.



2.

Point to Programs, then navigate to Accessories, then System Tools, then click System Restore.



3.

Choose Create a restore point, and then click Next.



4.

In the Restore point description box, type a name for your restore point, and then click Next.



5.

Click OK.

Run AVG in safe mode

Are you sure when AVG found it, you put it in the vault?

using safe mode with win XP:

If the computer is running it is best to shut down Windows and then turn off the power.



Begin by first clicking on the Start Button and then click on Turn Off Computer.



Now click on the Turn Off red colored icon to shut down your computer system.



It is best to wait between 15 to 30 seconds before you turn your system back on.



Turn on your computer and start tapping the F8 key on your keyboard.



Some Computers may display a keyboard error message if you begin tapping F8 too quickly.



Restart your computer again and begin tapping the F8 key a brief second or two later.



When the Windows Advanced Options Menu appears, Choose the Safe Mode option and hit Enter.



Windows will now boot your computer up in Safe Mode

1) Get antispyware softwares - Spybot's free http://www.safer-networking.org , AdAware SE is having a good free version - http://www.lavasoft.com

Spyware Doctor has a free version which only prevents incoming ones, but doesnot cure the existing threats



2)Get a better firewall. Zonealarm has a free version. Windows firewall is crap. It doesn't control programs which u have communicate with their servers, so doesn't prevent trojans communicating to download more. Free version of ZoneAlarm at http://www.download.com/ZoneAlarm/3000-10435_4-10039884.html?tag=hed



3) Ewido(now owned by AVG) is great software against trojans. It's full evrsion is paid, but have some 30 day trial full version. get it from http://www.ewido.net and have a free version as well .Ewido also has a great free online scan and removal. check it out as well.

I'd stick with higher quality products then freeware for trojan horses. Usually freeware for trojans might be some of the problem fixed or none of the problem fixed and in the end you just waste time. My recommendation is Trend Micro but it does costs money. But time wasted with free programs is lost money so think it as you'd save money in the end.

Prevention is the best method. Sounds like you need to get a good Virus Protection Program and be sure it is set up properly to protect your computer. Other wise you are just going to keep getting them nasty little critters. I use Nortons and have it come on at start up. I have it set to automatically scan, do updates, emails, downloads and more. Norton will also clean out your puter before installation. Good Luck, Elaine

Now for some informed reading, courtsey of 2-spyware Research centre.

Anti-Spyware contains the list of all known legitimate anti-spyware programs that can effectively detect and remove spyware, adware threats and other kinds of computer parasites from the system. Listed programs have been carefully tested by the 2-spyware.com research center and successfully passed our strict tests. This means that all of them can quite precisely recognize a particular pest, completely disable it by terminating its processes, deleting its essential files, registry entries and other related objects and eventually clean the infected system ensuring that no unsolicited programs will stay and attempt to violate your privacy and harm your computer.



All the products in Anti-Spyware category really work, do not deceive the user by producing false positives and cannot damage a compromised computer while eliminating found malware.

Such review also includes program screenshots, information about its price, implemented features, performance and general effectiveness. We rate tested programs by giving marks from 1 to 100. The higher mark a spyware remover gets the more effective it is. Please carefully read each review, pay attention to the rating mark a program got and read comments published by other visitors. This will help you to make a wise choice and compare your current anti-spyware program with other modern solutions on the market.



If you cannot find a particular spyware remover in anti-spyware category, take a look on the category of corrupt tools. It contains the list of rogue, fake, illegal, even harmful applications that definitely cannot correctly detect and remove various security and privacy threats and therefore must be avoided.



Additionally we provide the list of recommended anti-spyware software that got the highest marks and therefore is the most effective. From the personal experience we can tell that one spyware remover is not enough, different programs find different parasites. You need to do a wise choice.

I think you should use Spyware Doctor. Search it up. In my opinion, it's an excellent virus remover and also has a pop-up blocker.

AVG is totally worthless. It is JUNK. I recommend antivir free edition.
