What are script viruses and how to remove them? [Guide]

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. A Script Virus usually comes from webpage advertisements and is therefore wide-spread. Have you ever opened your web browser only to find that your homepage has changed? This may have been caused by a Script Virus. 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. 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. Let’s take a look at how Script Viruses propagate and how to stop them.


Almost 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). A Script Virus is spread via webpages and has several properties such as being easy to program, malicious, and highly infectious.

As you read about the properties of Script Viruses above, you might have noticed that they can be triggered by users themselves, such as when you click on an infected advertisement or open an e-mail attachment that is infected. Hence, the best way to prevent Script Virus propagation is to avoid making direct contact with the infected files and questionable webpages. Here are some steps you can take to avoid infection and remove suspected files.
