Do unexpected messages pop up, or do programs start automatically?

Some viruses can damage Windows or some programs. The results of such corruption can include unexpectedly displayed messages, programs started or closed automatically, or the sudden shutdown of Windows.

Is the modem or hard drive working harder than necessary?

An e-mail virus works by sending many copies by e-mail. One indicator of that is the activity light on the broadband modem that is constantly on or flashing brightly all the time. Another indicator is the sound of the hard drive of the computer working continuously. These symptoms do not always represent the presence of a virus, but they can indicate a virus infection combined with other problems.

Slowness on a computer can be caused by many things, including a virus infection. Virtual threats such as viruses, worms, Trojans, and other malicious programs, perform tasks that consume many resources, causing the system to run slower than usual.

Applications do not start

When one or more applications do not respond or programs stop working, it is clear that something is not working correctly. There are certain malware that directly attack certain applications or programs, preventing them from executing correctly.

Internet does not connect or is slow

Loss of connection to the web is another common symptom of infection, although it also can be a drag with the server, modem, or router. When the connection slows down, chances are high that malware is connecting to a URL or opening separate connection sessions, reducing your available bandwidth, or making Internet use virtually impossible.
