HOW IT SPREADSĪlmost all of the Script Viruses have these common features: prefixing itself Script (i.e., Script.Redlof) and being written via a scripting language (a very high level programming language, operating at a high level of abstraction, such as JavaScript). Let’s take a look at how Script Viruses propagate and how to stop them. A Script Virus causes a lot of trouble for computer users, many of whom are casual web surfers with no knowledge of their system’s infection. The consequences of being infected by Script Viruses include the modification of the front page of a web browser, changes in your registry (for Windows system users), slower system performance, and so forth. Have you ever opened your web browser only to find that your homepage has changed? This may have been caused by a Script Virus. A Script Virus usually comes from webpage advertisements and is therefore wide-spread. It’s quite common for anyone who has web surfing experience to have come across a certain type of webpage virus, namely the Script Virus.
