Removing Viruses From Your Computer

Removing Viruses From Your Computer



Removing Viruses From Your Computer
One of​ the​ biggest threats that computer users are facing today is​ the​ probability of​ a​ virus invasion .​
It is​ possible that your own PC might have been infected with a​ virus that you have downloaded unknowingly from the​ internet,​ or​ copied from other removable storage Medias like floppies or​ compact discs .​
While some viruses are capable of​ doing extensive damage to​ your system,​ some may be completely harmless but simply annoying .​
Whatever the​ problem is,​ it’s always best to​ try and remove these malicious applications (manually or​ using anti-virus software) before they can cause any harm,​ and without deleting sensitive and important files on​ your computer.
There is​ no one set of​ instructions you can follow to​ deal with a​ computer virus because all viruses are different .​
There may be variants but each variant may behave differently and independently .​
The steps mentioned here are general remedies that may be used if​ ever your system is​ infected with a​ virus.
Active and inactive viruses:
A virus is​ usually located in​ a​ file,​ and it​ can be in​ one of​ these two states: active and inactive .​
When the​ infected file has not been executed,​ the​ virus is​ in​ an​ inactive state,​ and is​ not necessarily harmful .​
In such cases it​ is​ enough to​ delete the​ file .​
When the​ infected file begins execution (when started by user,​ by operating system,​ or​ by another program),​ the​ virus changes its state from inactive to​ active,​ and begins to​ perform harmful activities on​ the​ system.
Identify the​ virus:
There is​ a​ webpage for every virus that has ever been identified by anti-virus companies,​ that explains how the​ virus executes itself,​ and usually how to​ remove it​ and disinfect the​ system .​
Here’s one useful resource available for identifying viruses on​ your computer:
The Symantec Antivirus Research Center Online Encyclopedia or​ the​ McAfee Virus Information Search Center (www.symantec.com/avcenter/vinfodb.html): Try using these virus search engines to​ locate information about the​ virus on​ your computer .​
The Symantec search is​ capable of​ identifying viruses according to​ the​ symptom experienced by the​ system (such as​ the​ subject line of​ the​ email message that contained the​ virus or​ the​ error message the​ virus causes on​ the​ computer),​ but it’s best if​ you know the​ name of​ the​ virus beforehand .​
Also remember that different computer viruses produce different symptoms.
Using Anti-virus Software:
Once the​ virus has been identified,​ the​ best thing to​ do next is​ to​ run an​ anti-virus software,​ scan and clean the​ system .​
If you have anti-virus software on​ your computer (most users do),​ make sure the​ software is​ up-to-date.
Most anti-virus software run periodical,​ scheduled or​ manual scans on​ your computer according to​ preference,​ and if​ fully updated,​ will promptly identify any malicious activity or​ files on​ your system .​
You then have the​ options of​ deleting,​ quarantining or​ analyzing the​ virus depending on​ the​ type of​ antivirus you employ .​
If you’re not too acquainted with the​ software,​ the​ only recommendation is​ to​ immediately delete the​ file,​ thereby eliminating any threat posed to​ your system’s security.
Protect yourself from future threats:
Once you have removed the​ virus(es),​ it​ would be a​ good time to​ make sure your computer is​ protected from future threats by following these simple steps:
1.Make sure the​ anti-virus software on​ your computer is​ always up-to-date
2.Run real-time protection if​ your anti-virus has the​ feature (most anti-virus software do)
3.Do not download or​ run any suspicious or​ unrecognized email attachments or​ file from the​ internet
4.Always run your anti-virus and scan any removable storage Medias before using them
Contact technical support:
If you can’t solve the​ problem yourself,​ you should contact technical support immediately by phone or​ email .​
Every anti-virus company has one .​
They will be able to​ help and guide you .​
Do not take any drastic steps,​ like formatting any of​ your drives,​ if​ you don’t have prior experience.
