OpenCloud AV is a fake anti-virus application that creates misleading alerts and hijackers your web browser to lead you to give up money for its fraudulent software activation process. Our malware experts strongly discourage you from spending money on OpenCloud AV even if it ceases its attacks. Since OpenCloud AV is incapable of performing any of typical anti-virus or security functions that you would expect from an anti-virus product, you shouldn't try to use OpenCloud AV's scanner or other aspects of its fake features, since these actions merely give OpenCloud AV the opportunity to expose you to other types of false warning messages.

OpenCloud AV - Not the Kind of Cloud You Want Your PC Plugged Into

OpenCloud AV exhibits the same type of harmful behavior that our malware researchers have also observed in other members of the FakeScanti family such as (among many other possible examples) Security Guard, Sysinternals Antivirus, WireShark Antivirus, Milestone Antivirus, BlueFlare Antivirus, Wolfram Antivirus, OpenCloud Antivirus, OpenCloud Security, Data Restore, AV Guard Online, Cloud Protection, AV Protection Online, System Protection 2012, AV Security 2012, Sphere Security 2012, AV Protection 2011, Security Guard 2012 and Super AV 2013. Although many of these functions may imitate the outer appearance of an anti-virus program, OpenCloud AV has no real virus detection or removal features, and you should never try to use OpenCloud AV in the same way that you'd use a legitimate anti-virus product. Standard OpenCloud AV attacks can include:

  • Pop-up messages that alert you about nonexistent infections or try to convince you that various PC components are damaged.
  • Browser hijacks that redirect you to OpenCloud AV's website or prevent PC security websites from loading. OpenCloud AV may attack your browser via the Hosts file or via proxy server settings; in the latter case, you may see an error like the following one frequently:

    "Proxy server is refusing connections"

  • Programs may be blocked by OpenCloud AV without case, especially security-related programs that could remove OpenCloud AV.

Getting Your PC Back to Sunny Days Without OpenCloud AV

OpenCloud AV should always be removed by appropriate anti-malware software whenever you have access to such software, since manual deletion attempts can cause damage Windows. Our malware researchers also recommend that you identify and learn to ignore OpenCloud AV's many fake alerts; these messages can contain a wide range of misleading and inaccurate information that can lead you to harm your PC unknowingly, as seen with these examples below:

svchost.exe was replaced with unauthorized program.
It has encountered a problem and needs to close.
If you were in the middle of something, the information you were working on might be lost.

Safe Mode is considered the easiest-available method of disabling OpenCloud AV so that you can delete OpenCloud AV from your computer. If OpenCloud AV attacks persist in Safe Mode, you may want to attempt to fake an activation process with the following code: 'DB038748-B4659586-4A1071AF-32E768CD-36005B1B-F4520642-3000BF2A-04FC910B.'

Finally, you can rename security program files to use generic file names (such as explorer.exe) to prevent OpenCloud AV from blocking them. None of OpenCloud AV's attacks cause permanent harm to your software or Windows, so once you've removed OpenCloud AV properly your PC should return to top health.

    Id love to choke the lil basterds that came up with this... Hope i find them. I'll have my own fun with'em. Messed with the wrong poor person this time!

  • Joe says:

    The code did not work. Got a message that said it was invalid. I restarted my computer in SAFE mode, found the location of the file and deleted it. It took a while but I was able to get the Windows Firewall on again. However, I am still having trouble getting my virus software to work. I will be getting a new virus software as obviously 2012 Titanium Micro Internet Security that I recently purchased...sucks. Thanks for your help. Nice to have a second computer when the other one has a problem.
