OpenCloud AntivirusOpenCloud Antivirus is a fake anti-virus program that uses traditional scamware-style tactics to steal your money and finance-related information. SpywareRemove.com malware researchers have found that OpenCloud Antivirus, like its brethren, is happy to create fake virus alerts while it asks for your money so that it can 'fix' these imaginary problems. Other issues that may be caused by OpenCloud Antivirus include browser hijacks, negatively-altered system settings and problems with security software. You should remove OpenCloud Antivirus with an anti-malware program of good repute, since OpenCloud Antivirus will conceal its components in diverse locations, as well as borrowing the names of critical Windows system files.

Although OpenCloud Antivirus tries to look like a new and independent product that will fight viruses on your PC, OpenCloud Antivirus is really a clone of older rogue anti-virus products from the FakeScanti family that include Security Guard, Sysinternals Antivirus, WireShark Antivirus, Milestone Antivirus, BlueFlare Antivirus, Wolfram 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, Super AV 2013 and OpenCloud AV.

The Toxic Rain Inside of This OpenCloud Antivirus

OpenCloud Antivirus, like other forms of fake security software that our malware experts have analyzed, is used primarily for the creation of false positives or fake infection warnings that mislead you about the state of your PC. Error messages from OpenCloud Antivirus can appear in your taskbar, after OpenCloud Antivirus pretends to scan your computer or even at random in the form of browser popups. One example of OpenCloud Antivirus's fake errors is shown here:

Security Warning
There are critical system files on your computer that were modified by malicious program. It will cause unstable work of your system and permanent data loss. Click here to undo performed modifications and remove malicious software. (Highly Recommended)

OpenCloud Antivirus will also pretend to detect specific infections that aren't on your PC such as Trojan-Downloader.JS.Agent, Trojan.VBS.Qhost and Trojan-Downloader.JS.Romora. In return for offering to remove these infections that it made up to begin with, OpenCloud Antivirus will ask you to spend over fifty dollars to register its software. Instead of wasting your dollars on an anti-virus program that has no virus-fighting features, you may want to consider faking registration with the code 'DB038748-B4659586-4A1071AF-32E768CD-36005B1B-F4520642-3000BF2A-04FC910B'. The above code has been known to work on other rogue anti-virus applications in the same subgroup of OpenCloud Antivirus.

Dispersing OpenCloud Antivirus for Sunny Days Ahead

Although removing OpenCloud Antivirus with an anti-malware product should be a common-sense solution to an OpenCloud Antivirus infection, other attacks by OpenCloud Antivirus may complicate your attempts to delete it, such as:

  • Browser hijacks that block websites or redirect you to hostile sites like OpenCloud Antivirus's fake storefront. Due to the proxy server-based method that OpenCloud Antivirus hijacks use, you may see the following error when you're blocked from a website:

    "Proxy server is refusing connections"

  • Blocked security programs on your PC. OpenCloud Antivirus will attempt to prevent you from using anti-virus and other forms of anti-malware programs, and may also attempt to block Windows utilities like the Task Manager.

In both cases, the simplest route to circumvent these OpenCloud Antivirus blockades is to use Safe Mode or boot Windows from a USB drive. This will let you access the operating system without triggering OpenCloud Antivirus, which can then be deleted (including its fake system components, such as csrss.exe, and its hidden Temp directory files) with ease.
