How to remove OpenCloud Antivirus?
What is OpenCloud Antivirus?
OpenCloud Antivirus is a new name for fake antivirus programs from the same family as Wolfram Antivirus. This family of rogues (sometimes called WinAVPro) is installed by trojans and creates one file with the same name as system file (csrss.exe), with a link from startup folder so this file would be executed once system starts. Note, that OpenCloud AV name is similar to legitimate program from Panda.
Upon each reboot OpenCloud Antivirus will execute itself and will try to convince you into running a system scan. This scan will produce fake results with various infections found in harmless or non-existing files. It will exaggerate the danger of “found” threats and will try to convince you into paying for full version. However, this is a scam and should not be trusted. You should remove Open Clould AV instead.
If you do not scan your PC, your work will be disturbed by various alerts. For example, It will show that your PC is infected with Zeus Trojan:
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?
Warning! Infection found
Unwanted software (malware) or tracking cookies have been found during last scan. It is highly recommended to remove it from your computer.
Keylogger Zeus was detected and put in quarantine.
Keylogger Zeus is a very dangerous software used by criminals to steal personal data such as credit card information, access to banking accounts, passwords to social networks and e-mails.
Warning: Infection is Detected

As one can see, OpenCloud Antivirus can not decide if Zeus is trojan or keylogger. There is no systematic approach to whole its “database”, which consists of false infection names and scary messages.
You can also get an Open Cloud Antivirus alert that you have sent an offensive email to someone. This might scare office workers more than alerts about some sort of infection. However, all these messages are false and should not be trusted.
