Opera is a modern browser that literally any user is familiar with. The functionality of this browser is capable of loading almost all web resources in a matter of seconds. But like all programs installed on a computer, Opera is subject to many factors, both from the system itself and from the user, which can make it incapacitated.
Loss of file path
The first and main reason why Opera does not start may be the loss of the path to the installed file. This is the case when the user tries to open the program by clicking on the shortcut, and instead a search box appears in which to indicate where the program is installed. The reason for these errors is the system itself. After an incorrect restart of the computer or its sudden shutdown, the system can sometimes "forget" in which place on the disk the file was loaded. After all, the hard disk fills up unevenly. To prevent such things, you should regularly defragment the disk and clean the registry. You can fix this error simply by specifying the path in the search box. Usually, if the settings were not changed during installation, the browser is installed on the local drive (C:) in the Program Files folder.
Another reason can be a virus infection. Such an unpleasant thing can get on your computer when you download something from the Internet from unverified sources. Or when using a flash drive, which was previously with the user with the infected computer. The most popular virus of this kind is Recycler. Visually, it is presented in the form of a folder with the above name. If something like this gets into the folder with the program, then it will definitely disable it. Even if the antivirus has not detected that malicious software is present on the computer, it will clearly look like an increase in file weight. The amount of free disk space will constantly decrease. There are two ways to solve this problem: a thorough scan of the entire system with an anti-virus program with the latest version of anti-virus databases, or formatting all local drives, followed by reinstalling the OS.
Blocking by a third-party program
The opera could also be blocked by a firewall. This is a standard Windows program, the main task of which is to control the connection of applications to the network. This certainly increases the security of the computer, but in some cases it complicates the work of some software. Typically, before launching an application that requires network access, the firewall does not block it itself, but provides a choice to the user. But sometimes the blocking happens automatically. To restore Opera to work, go to the control panel and turn off the Windows firewall.
