Computer Scanners

Apart from the hardware devices there are computer scanners needed to scan the computer system against certain viruses. The computers should be well guarded against the viruses which may disrupt the proper functioning of the computer or may cause hardware problems in the parts of the computer.

The computer scanners are certain software programs that help to the guard the computer against any kind of problems which may hamper the functioning for the hardware of the computer so they have much importance in the field of computers.

There are certain computer programs that make cause security threat to the computer. These may be in the form of computer viruses or worms or Trojan horses. Computer virus is a program which replicates itself an inserts its copies into other executable programs or documents on the computer scanners and this is referred to as infection and infected file is known as a host.

These infected programs can be deliberately or accidentally written by the computer programmers. The viruses are written as pranks, research projects, vandalism, to gain financially, or to attack certain specific products of a company and they are considered to be creative and art works by their creators.

These viruses can be destructive or maybe only annoying. When a virus troubles on a specific day it is known as a bomb. A time bomb is which occurs on a particular date or time and a logic bomb takes place then there is some action by the user that may trigger of the bomb.

Today the computer scanners which were known as antivirus software which helped in protecting the computers from the viruses havoc with extended such that they cover worms and all the other threats which may cause any problem in the computer and these are known as spyware, adware had had identity theft which may also be a concern for the computer operators. These viruses not only cause a problem for a single computer but they spread just like the viral infection in the humans and in the same way be spread from one completed to another making themselves more dangerous.

Now let us see how to get away from these viruses. Internet is one of the major sources from where the viruses may the computer. Today windows server service runs on all the desktop or laptop systems and so the vulnerability to the remote attack increases. For this reason the patch can be applied from the Microsoft update site. Not only this but a downloaded file or an e-mail on any other software can be a carrier of the infection or a virus.

Safe computing habits protect the computers from the malicious software, viruses or internet related attacks. The software patches should be updated, antivirus programs should be updated, the firewalls should be used, anonymous point to point file sharing should be avoided, the unexpected e-mail attachments should not be opened and one should never open the links in an unknown e-mail.

The auto complete feature should be disabled as along with the automatically filling up of the forms and logging on to secure sites it also makes entry for Trojans and hackers easily into the personal data.

One should always make sure that there is no change in ones trusted sites zone if one is using any spyware and adware which may cause to add certain miscreant links to the list of the trusted sites.

If there are any e-cards in the e-mail then that e-mail should be marked as spam and should not be opened for viewing as it might contain any Trojan like Haxdoor Trojan which is said to be a powerful backdoor with the rootkit Capabilities by F-secure. This type of the e-mail should never be replied back.

Adware is software through which the advertisements are displayed on the computer. These ads suddenly pop up on the screen even if a person is not browsing the internet. These ads can be attached to any free software which one downloads from the internet.

Spyware is another kind of software that in sends the user information without the users permission to any third party which may include the password and username of the user and the user will then onwards start receiving unsolicited advertisements.

Most of the people dont even realize that their computer is affected by the spyware or any my virus. It is only when the computer doesnt perform well that one comes to know that the computer was infected. But removing these is tougher than preventing them from entering the system. This can be done by using antivirus computer scanners.

Today with the changing scenario the antivirus products have included adware and spyware scanning. The McAfee antivirus, Trend Micro PC-Cillin 2004 and Norton antivirus 2004 can scan for the adware and spyware.

Even many internet service providers also provided protection from adware and spyware like America online. The pop up blockers can also be installed and which easily available onj the internet is being MSN toolbar or Google toolbar which will block all the useless time wasting annoyers. Not only this but one can also use the adware and spyuware removal tools which can be found at the spyware protection and removal guide available on the web. And it may be needed to run these computer scanners softwares in the safe mode as at times it may be impossible to remove a problem when the computer is running because even the infection can be running as a process.

Yet still there are more places from where one can gain knowledge if one suspects that the computer is infected. These are the newsgroups most familiar being the windows XP General and the Windows XP Security and Administration newsgroups. So the computer must be provided with the computer scanners which can scan and remove the viruses and other adware and spyware programs which can adversely affect the computer.
