XP-Antivirus Information and Removal

XPAntiVirus For the past few days, I have been following with the latest malware called XP-antispyware. I was of the opinion that this is only spread via its own website and when downloaded and installed. But today it proved me all wrong. I was searching google and when I opened one result, to my surprise, another popup opened breaking all my popup blockers stating that my computer had some spyware and that I needed to scan for spyware using XP-Antivirus. I just closed the Window and another dialog box appeared which I captured:
I didn’t press OK. Just clicked the red Cross and everything was fine. I have NOD32 Security Suite and I have the latest definitions installed. It should have caught this dangerous page but it didnt.
XP-Antivirus is still new and can affect even with

your antivirus installed. So be aware of the danger.

How to stay away from XP-Antivirus

As I have already mentioned that the detection of this malware is really very poor, so you should also be careful about what you are doing. Just stay away from the following sites:

  1. XpAntivirusonline.com
  2. XPOnlinescanner.com
  3. XPSecuritycenter.com
  4. XPAntispyware.com
  5. XPAntiviruspro.com
  6. XPAntivirus2008.com
  7. XPAntivirus-scanner.com
  8. XPAntivirus.com
  9. XPAntivirussite.com
  10. XPCleanerpro.com
  11. XPAntivirussecurity.com

In the last one month or so, the creators of this malware have created so many sites and it is expected that the variants will keep on coming. Please note that this malware can install automatically so please DONOT try to open any of the sites above.

    I think that manual removal is the most effective way to get rid of XP antivirus, though regretfully not the easiest. For ordinary users out there, deleting entries from the Windows registry can quickly become a worse experience than this scam itself. However, it mutates so fast that antimalware programs work on certain PC’s and don’t work on others, so manual check and step-by-step guide is always a better idea than a blind belief in some “powerful remover”.

    Manual remove does work but i have found you have to double check ourself to get all of the files removed. If some are left behind you end up still getting the popups. Also, be careful with the registry entries, if you are not sure then don’t mess with your registry or you may end up re-installing windows!

    Thank you AntivirusExpert and Techie Bob for your expert comments. May be we should also work on a removal tool for this malware because it is spreading rapidly. I’ll try to make one removal tool specifically for XP-Antivirus.

    Run smitfraud.exe to remove XP Antivirus. It’s a free download.

  6. Haz

    Disable System Restore, Run “SmitFraudFix” & Followed By “RogueFix” (Run Both In Safe Mode)
    Run “Disk Heal: & Lastly “SuperAntiSpyware”.
    Enable System Restore:-)
