How to delete viruses from the device


Viruses


Without the knowledge and against their desires, a person can download a program, or a piece of code, on another computer, and these programs, called viruses, can repeat themselves. Some viruses may use available memory, or system hangs, such as simple viruses, and may be transmitted over networks and bypass security systems, such as dangerous viruses. And many anti-virus programs have now spread, after a virus struck the network used by the US Department of Defense, and several universities, known as Arbant, in 1987. It is possible to know if the device is infected with a virus by:

- Browser crash and instability: Some signs may appear when using the browser, such as suddenly closing or stopping responding, new tools being added to the toolbar, unrelated websites opening, or clicking on a link and not responding.

- Poor system performance: computer performance might be impaired, such as an internet connection stops, the device has stopped working and taking a long time to respond, blocking some programs from downloading or updating, adding icons, or installing suspicious software on the desktop.

- Advertisements: Ads are displayed permanently, whether the browser is closed, or open, as new pages and search results are opened only to display ads.
