OpenCloud Antivirus is quite a bit more aggressive than the previous versions from the same scareware family: Wolfram Antivirus, BlueFlare Antivirus and Milestone Antivirus. It performs fake system scan and detects exactly the same infections on entirely different computers. It's a false claim meant to extort money out of you. What is more, Open Cloud Antivirus sets up a proxy server for your LAN connection and either blocks certain websites or redirects to malicious or infected websites. It also blocks legitimate applications claiming that they are infected or hijacked by malicious software, usually spyware or a Trojan horse.
Security warning:
The file C:\WINDOWS\regedit.exe is infected.
Running of application is impossible.
There is also this fake Windows security alerts stating that a Zeus Trojan is requests an unauthorized access to your computer.
Windows Security Alert
To help protect your computer, Windows Firewall has blocked some features of this program.
Do you want to keep blocking this program?
Zeus Trojan
And there's another one claiming that the svchost.exe process was replaced with malicious one. OpenCloud Antivirus creates an autorun registry entry to run a file called csrss.exe every time Windows starts. Please do not confuse it with the legitimate one which resides in C:\Windows\System32\csrss.exe. The Trojan file then loads the main OpenCloud Antivirus executable OpenCloud Antivirus.exe.
