MALACIOUS SERVERS

With the growing use of Internet, online business has become one of the major types of business these days. As this mode of business is quite fast and also convenient at the same time, more number of people are also getting associated with it day by day. As a result, online business has become a fast growing one in short time. People of different industry verticals are going for online business these days. We often buy products or services through internet. Similarly, while buying a domain, you often go for online registration. Service providers are also increasingly opting for online transactions.

For all the online transactions, web servers are required. However, these web servers are being surreptitiously used by unscrupulous users to float out malicious programs, which would creep into systems as Trojans. Trojans as we know appear to be harmless to the system files but once into the system, they would auto-enable itself as JavaScripts and download the actual virus programs from the internet without the knowledge of the user.

A survey conducted by Kaspersky shows that 28% of 1.9 million servers are infected with viruses. So you can easily imagine the number if we consider the individual machines that regularly get connected to various servers. When accessing a web server for viewing a website, people often download PDF files. These PDF files are getting affected by the viruses like Win32.Pdfka and Exploit.Win32.Pidief. In most systems antivirus software are taking care of the security issues, but at the same time, it is always a cat and mouse game between the security software and the malicious programs.


However a help desk specialist know how to extract the maximum out of an antivirus software. S/he knows in details the security involved in a router. For better security, it is always good to configure it at your own, rather than relying on the default configuration.

You need to follow the below mentioned steps:

1. Configure your antivirus software properly.

2. Use a version later than 9.3 for Adobe.

3. Always download the specific file in a folder that you have created already. Now, right click on the folder, scan the folder for threats and then open it. Do not open the file before you scan it.

4. Do not be fooled with file extensions. A“.exe” could be the last entry after a number of periods like “a1v2q.png.exe”. These files could be harmful.

5. If you get a virus alert from an UNKNOWN antivirus software that you haven’t ever installed, then definitely your computer is on the verge of getting infected. Be cautious, do not access any other file and immediately run your antivirus scan (go for renowned antivirus that you have bought, like AVG or Norton or McAfee etc.)
