The Threating Computer Viruses Functionalities as Computer Worm & It's Ultimate Free Solution

Computer worm:

A computer worm is a standalone malware computer program that order replicates itself in to spread to other computers. Often, it uses a computer network to spread itself, relying on security failures on the target computer to access it. Unlike a does computer virus, it not need to attach itself to an existing program. Worms almost always cause at least some harm to the network, even if only by consuming bandwidth, whereas viruses almost always corrupt or modify files on a targeted computer. 

Viruses   

               A computer virus is malware attached to another program (such as a document), which can replicate and spread after an initial execution on a target system where human interaction is required. Many viruses are harmful and can destroy data, slow down system resources, and log keystrokes.  Beware of Viruses that you may receive from the Internet. Viruses can attack your computer when you download files or even when you receive e-mails. 

    To protect your computer from viruses on the Internet, don't download tiles from sources that you don't know are safe. Viruses are usually hidden in programs and activated when the programs run. They also can be attached to certain other types of executable files, such as special-action Web files and video files. Generally, when you're about to download a type of file that could contain a virus, your browser will display a warning and ask whether you want to open the file, or save it to disk. If you're confident that the file comes from a trustworthy source, you may want to open it. If you're not sure, you may want to cancel your download. Another way to verify the identity of a site is to check whether it has a Web site certificate, naming the site's originator. With Microsoft® Internet Explorer version 4.0, you can check a Web page's certificate by right-clicking on the page, clicking Properties, and then clicking Certificates.

There are many anti virus programs that can scan your computer for viruses, inoculate against known viruses, and maybe even repair damage caused by a virus. To get the benefit of such a program, make sure you run it as recommended (you may be able to schedule it to automatically scan your computer on a regular basis) and get updates to the program, which include information about new viruses.

In this day and age 2020, the two are one and the same — there’s no distinction when it comes to antivirus vs. antimalware. Nobody’s offering software that detects and removes viruses while ignoring worms,Trojans, spyware, and ransomware. Even if the product name says “Antivirus,”  a close reading should reveal that it offers wide-ranging protection (and if not, don’t use it).

• Good antimalware software packages also monitor email clients and web browsing, and maintain a database of known and reported dangerous sites. 
• If you try to visit a site known to carry a malicious payload, your antivirus software stops you from even loading the website.
• Scanning system will run the PC more speedily.
• It detects the New Downloaded Installed file safes or not.
• Likewise, if a suspicious attachment comes in via email, your antivirus software detects it and moves the attachment to a quarantine folder where you are barred from opening it.
