How to stop pop-ups and remove fake software, spyware, trojans and viruses:
Download, install, update and scan your computer with both Malwarebytes and SuperantiSpyware, delete anything they find, if this fails to completely remove the virus/spyware download then update Avast and run a boot scan (click schedule boot-time scan and restart your PC), all the software below is free and safe to use.
Malwarebytes: http://www.malwarebytes.org/mbam.php
SuperantiSpyware: http://www.superantispyware.com/
Avast Anti-Virus: http://www.avast.com/eng/avast_4_home.html
To protect your PC in the future you’ll need to install anti-virus software and a firewall, id recommend using Avast and Comodo Pro firewall both are very effective and completely free, you should also switch to Firefox 3 if you are browsing with IE as its much safer and a lot easier to use. (links on my profile)
you need a trojan Remover (not an antivirus remover as they are not the same)
Here are the instructions

http://www.symantec.com/norton/security_response/writeup.jsp?docid=2008-072215-0522-99
Scan with SUPERAntiSpyware then Malwarebytes’ Anti-Malware. You may have to scan in safe mode to completely get rid of it. Once each scan is complete and the malware quarantined, you should reboot to complete the removal process.
Download, install, update and scan with the following free:
AVG Free from http://free.avg.com/ – this is an anti-virus, ensure that you only have one anti-virus program installed on your computer
You can have multiple anti-spyware/malware/adware programs to scan, ensure they are legitimate. I suggest the following:
SUPERAntiSpyware Free Edition from http://www.superantispyware.com or download.com
Malwarebytes’ Anti-Malware…
Valid downloads of Malwarebytes only come from these sites:
http://www.download.com
http://www.majorgeeks.com
http://projects.securitywonks.net
Spybot Search & Destroy from http://www.safer-networking.org – activate TeaTimer and ensure that you immunize every time you update (Spybot S & D updates on Thursday)
Ad-Aware 2008 Free from http://www.lavasoft.com
CCleaner is a good tool to run once in awhile http://www.ccleaner.com/
Firefox is a much safer browser than IE http://en-us.www.mozilla.com/en-US/firefox/3.0.5/releasenotes/
If all else fails I suggest you register with the Spybot Search & Destroy Forums and post your problem in the Malware Removal Forum… they are excellent at talking people through the process of cleaning their computers. http://forums.spybot.info/

Final Running System Restore
If your computer seems to be unstable, you’ve done a thorough anti-virus and anti-spyware scan, and you’ve been unable to remove any suspected software packages through Control Panel, give System Restore a try. To roll back your computer settings to a previously saved restore point:
# Click the Start button, then select Programs / Accessories / System Tools
# Click System Restore.
# Choose "Restore my computer to an earlier time" then click Next.
# Select a day on the calendar, a restore point description, then click Next. http://askbobrankin.com/system_restore.html
A trojan horse is an executable program that is designed to disrupt or hijack applications on your computer. The reason why these programs are developed are often to initiate other attacks from more advance malware such as spyware.
You need to kill the process and the dll files attached to the trojan. You need to edit the msconfig and registry to stop it from loading startup. Here is a good tutorial:
http://www.delete-computer-history.com/trojan-horse-removal.html
Two affirmations to start: 1) Do not reformat or use system restore to start from new as it is too harsh and you should do it only as a last resort.
2) Do not copy your documents elsewhere as this will only spread the Malware and do NOT use your Email until this is cleaned.
Now for the main part: This is Malware, deeply rooting itself in your system (some even hide in your router’s firmware). Virus scanners and the Restore Point Utility are not good things to use against such invasion for this reason alone.
Get the programs I listed from another computer (Internet Café, Public Library or friend’s computer) onto a USB stick as Malware blocks you from downloading protection. A word of caution, be sure to read all programs help files completely before using them. If you still cannot use MBAM, rename it Alteregobytes to confuse the Malware (but be sure to keep the .exe extension on it) and use it as alternative for part A of the following solution.
TRYING MBAM ALONE IS NOT ENOUGH AS YOU NEED A COMPLETE SOLUTION, here is one (use programs in the order stated):
A) Download MBAM (MalwareBytes’ Anti-Malware): http://www.download.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html?part=dl-10804572&subj=dl&tag=button – Install the application and make sure a checkmark is placed next to Update Malwarebytes’ Anti-Malware and Launch Malwarebytes’ Anti-Malware, then click Finish ( If an update is found, it will download and install the latest version ).
Once the program has loaded, select "Perform Quick Scan", then click Scan ( The scan may take some time,so please be patient ). When the scan is complete, click OK, then Show Results to view the results. Make sure that everything is checked, and click Remove Selected ( When disinfection is completed, a log will open in Notepad and you may be prompted to Restart ).
B) Try the tricks and free programs I use: 1) Clean browsers junk.
Method One (now): In Internet Explorer (IE), click the Tools menu, then Delete Browsing History and in the box, click the Delete all button (bottom left) and Yes.
In Firefox (FF), go to tools, clear private data, make sure all boxes are checked and then click on the clear private data now button.
Method Two (Normal use: Every 14 days – Heavy use: Every 7 days): In IE, click the Tools menu, Delete Browsing History and in the box that opens, do these: a) click the button near Temporary Internet Files, click Yes and wait for the box that opens to close.
b) click the button near History, click Yes and wait for the box that opens to close and finally, click the close button (bottom right) to finish.
In FF, Go to tools, clear private data and uncheck all except Browsing History, Cache and Authenticated Sessions boxes then click on the clear private data now button.
Note: Close browser when done to clear cookies still in memory. For other browsers or versions of the programs, check help files for guidance on doing cleanup.
2) Turn off the restore point utility ( Guide for XP: http://support.microsoft.com/kb/310405 and Vista: http://windowshelp.microsoft.com/Windows/en-US/Help/9f6d755a-74bb-4a7d-a625-d762dd8e79e51033.mspx )
3) Use this free cleaner: http://www.glaryutilities.com/gu.html to remove junk and remnants files.
4) Use a "Disk defragmenter".
5) Turn restore point utility back on. (see part 2)
6) Do not use toolbars (spyware).
7) Persisting problem after this, get Avira: http://www.download.com/Avira-AntiVir-Personal-Free-Antivirus/3000-2239_4-10322935.html?cdlPid=10901492 plus an Email scanner ( http://www.spamdel.com/ OR http://www.glenn.delahoy.com/software/files/Inbox.htm ). Already have a scanner, make sure your virus database is updated BUT do not use AVG free (Too many false positives).
By doing so, you are on your way to being well protected BUT never relax your guard !
You should use an antivirus program and antispyware software, because your computer is now infected with viruses and/or spyware.
