During Internet surfing, different advertizing messages, banners, etc. quite often appear. Fortunately, there are several ways which will allow to get rid of them.
In network there are several types of banners: some of them just advertize the website, and others are harmful. As it is possible to guess, the second version is the most dangerous. Very often under a harmful banner disappears such which forces the user to download update for its browser. Certainly, you should not do it as the similar software or is updated by itself, or the user receives the special notification from a system on emergence of the new version. Key feature of such banner is that it will appear absolutely on all sites which are visited by the user and in most cases it is accompanied by computer infection with some malicious software.
Use of an antivirus for search of problems
In that case the first that it is required to the user - to check the computer for presence of viruses. It becomes by means of the antivirus installed on the computer. It is required to carry out full scanning and if some vulnerabilities or threats will be found, they need to be eliminated. Besides, some modern antiviruses, suggest the users to use an anti-banner - special means which will block all similar messages, therefore, to protect the user's computer from an adverse effect. A key lack of such service is that it, in the majority, is paid.
Check of properties of the protocol
Secondly, the user needs to check properties of the protocol. For this purpose it is required to pass into "Network and Sharing Center", in the menu to open the Change of the Network Adapter point at the left and to right-click on "Local area network". In a context menu it is necessary to open "Properties", to select "The internet protocol of version 4" and to click "Settings". In the appeared window it is necessary to look whether the IP address or the DNS server changed. In most cases their values should be the following: "Receive the IP address automatically" and "Receive the DNS server address automatically". If the tick costs not on these points, then they are required to be reassigned, and the problem can be solved.
It is possible to solve a pressing problem in one more way. For this purpose it is required to right-click on a label of the browser and to select "Properties". In the field "Object", the user needs to look at filename extension. If it differs from the original and, for example, has an appearance: opera.url, but not opera.exe, then is required to come into the root directory of the browser. 2 files with the name Opera, one of which is harmful, will be stored here. In order that to find it, it is necessary to look at a file type which value in this case will be "A label of the Internet", its size which is usually equal to 1 KB and the URL address. If the object has no URL address, then the problem consists in another. This address is the main point by which it is possible to determine that the file is infected. After its removal the user needs to come into "Properties" of the browser again and to change expansion to .exe. The same operation is required to be done also in case of use of other browsers.
