Important Warning About the Fan Check Virus (updated on 4/16/2025)

Hackers could be buying stolen electronics, making fraudulent purchases with your credit card and getting you into serious legal trouble without you even realizing it.

Don't let them. Do something about it before it's too late.

You should know that your computer may already be infected with the Facebook Fan Check Virus. Symptoms of an infected computer include the following:
  • System Slowdowns
  • Internet Browser Slowdown
  • Pop-ups
  • Settings being changed
  • Random System Crashes or Reboots
If you have any of these symptoms and you use Facebook, there is a very high (roughly 62.3%) chance that your computer may be infected with the Fan Check Virus, also known as Virus.Trojan.FanCheck.B8 and Virus.Trojan.FanCheck.A12.

The virus is spread by clicking on a link or granting a rogue Facebook application access to your Facebook account. The Fan Check Virus has been known to steal passwords to Facebook Accounts, MySpace Accounts, Web-based Email Accounts (Gmail, Yahoo and Hotmail are especially vulnerable to this due to their popularity), and SMTP/POP3 Email Accounts. It then attempts to propagate (with a success rate of 20%) to any contacts on compromised accounts by sending messages, tagging other people in photos and sending emails to other users with a link. The link may appear to be anything from a simple "Hey, check out this video at: [Link]," just "[Link]" (generally using an url shortener such at bit.ly), or even a Youtube-like video posted to a user's wall for his or her friends to see.

Our security team is currently working to prevent the spread of this Facebook Fan Check Virus.

Our tests have found that only NoAdware has been proven to automatically remove the virus. You can find it here. To fix registry errors caused by the virus, both Registry Easy (here) and ErrorSmart (here) will fix them. All three makers of the afforementioned programs have agreed to give users special rebates and coupons in effort to combat the lack of action from major antivirus companies and reduce costs to the user.

That being said, don't be a victim to something you can easily prevent. Don't let yourself be harassed legally or financially by hackers.

Facebook Fan Check Virus: Has it Spread to Twitter?


Has the Facebook Fan Check Virus finally made it's way to Twitter? There are reports of users starting to tweet malicious urls that infect users the very moment their computers load the malicious page. Hackers have begun using the mass network of Twitter followers to attach their links to some of Twitter's "popular trends."

As of current, this is just a preliminary report. Our team recommends that under no circumstances should users click on any links on Twitter, especially if the link is included with any popular trends.

As always, if you have clicked on a malicious link, please be sure to run a scan with your copy of NoAdware. Otherwise, you may fall victim to anything from identity fraud to credit card/check fraud to lost social networking and email accounts.
