The best Internet Browser, in my oppinion. Not dangerous at all, in fact, it is much more secure than Micro$coff's Internet Exploiter...

Best and probalby safest browser on earth
It's a web browser. How anyone could rate it as "harmful" is beyond me, yet someone has? It's far more secure than Internet Explorer, and a little more secure than even Firefox. About the only more secure browser is a limited text only browser like Lynx.

There is a backdoor (called svhost.exe (similar to svchost.exe, but there is no c)) that renames itself as Opera.exe process. So if you haven' t opened opera, but it is on task list, its backdoor..
Opera.exe is an extremly resistent Virus on my system. It redirects any links i click on, regardless of the browser used, to random banners and popups
There is a virus called Opera.exe .. and it has nothing to do with the browser Opera (i run Internet Explorer on a WinXp and suddenly a opera.exe took 99% of all cpu usage, and I am 100% sure there is no Opera installed on this computer. This opera.exe virus puts itself in the \windows or \windows\system folder.
in my opinion the best internet browser ever

Best practices for resolving opera issues

A clean and tidy computer is the key requirement for avoiding problems with opera. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
