2. Το κακόβουλο λογισμικό είναι ένα λογισμικό που
έχει σχεδιαστεί για να εκτελεί ανεπιθύμητες
ενέργειες για λογαριασμό κάποιου.
Το λογισμικό αυτό συλλέγει πληροφορίες από το
λογαριασμό κάποιου χρήστη,
στέλνει ενημερώσεις κατάστασης ή μηνύματα που
φαίνεται ότι προέρχονται από τον χρήστη,
ή γεμίζει το λογαριασμό του με διαφημίσεις που
εμποδίζουν τη σωστή λειτουργία του υπολογιστή.
3. Ένας ιός υπολογιστών είναι ένα κακόβουλο
πρόγραμμα υπολογιστή, το οποίο μπορεί να
αντιγράφει και να "μολύνει" τον υπολογιστή χωρίς
τη γνώση ή την άδεια του χρήστη του.
4. Αυτοί οι ιοί δρουν αθόρυβα.
Μολύνουν τον υπολογιστή και αναμένουν κάποιο
γεγονός ανάλογα με το προγραμματισμό τους.
Όταν ο ιός δούρειος ίππος εγκατασταθεί στέλνει
μέσω διαδικτύου τις κατάλληλες πληροφορίες στο
δημιουργό του ώστε αυτός να πάρει τον έλεγχο του
υπολογιστή και να χρησιμοποιηθεί σε διάφορες
παράνομες και επιβλαβείς ενέργειες.
5. Μεγάλη ικανότητα αναπαραγωγής
Ο τρόπος διάδοσης τους είναι το διαδίκτυο
Οι συγκεκριμένοι ιοί αποκτούν προσπέλαση στο
βιβλίο διευθύνσεων και αποστέλλει μολυσμένα
μηνύματα.
6. Οι χρήστες που κάνουν διπλό κλικ σε ένα
συνημμένο, επιτρέπουν στον ιό να εκτελεσθεί.
Ο κώδικας στέλνει αντίγραφα του εαυτού του σ’
όσους βρίσκονταν στο βιβλίο διευθύνσεων του
θύματος και μετά αρχίζει να καταστρέφει αρχεία
στον υπολογιστή του.
7. Για την ανίχνευση των ιών χρησιμοποιείται μία
βάση δεδομένων ή οποία περιλαμβάνει τμήματα
του κώδικα των ιών - ψηφιακές υπογραφές.
Με αυτό τον τρόπο αναγνωρίζονται τα μολυσμένα
αρχεία καθώς και αν ένας ιός έχει φορτωθεί στη
μνήμη του υπολογιστή.
8. Για να προστατεύσουμε το PC , μπορούμε να
εγκαταστήσουμε προγράμματα προστασίας.
Ένα τέτοιο πρόγραμμα εντοπίζει και διαγράφει
όλων των ειδών τις ηλεκτρονικές απειλές, τους ιούς
και τα spyware.
