Virus, Spyware, Malware Detection and Cleaning
Sometimes we harbor virus on our computers (PC) without knowing that they really are there. If we do know how these viruses behave, and the main feature and effect on our systems, we will not that there are a whole lots of them on our system and we thereby give them space to operate to their fullest until a lot of unrecoverable damage has been done to our system. This article will help you to detect virus, worms, spywares and malwares without anti virus and anti spyware software.
How to Detect Viral Infection of Your PC (Computer)
Wondering how to find out if your computer has a virus? Some of this virus might even appear invisible that our anti-virus can never detect them and we will generally believe that our system is virus free without knowing that our system is the home ground of well-groomed virus that deals with people’s files. So as to avoid this and even detect the status of virus on our system even without the help of anti-virus, I will like to talk about some things to take note of so that we can detect the presence of virus on our system.
Programs take too long to Load
Part of the things that virus does once it have the avenue to enter the system is to go and attack the files that once opened, they will have the avenue to spread to other file. The reason for this is that those file will always need some other file to enable them run easily and smoothly and those file needed are hidden on the system. But once they have the opportunity to attack those files, it will aid them in spreading to other hidden files that are on the system.
As tis is been done, it will make it hard for anti-virus to detect them and if they eventually detected, the anti-virus that did not have the capacity of healing them will not be able to deleted those files because some of those hidden files are important operating system files that must be deleted because they aid in the smooth running of the O.S.
Once these files are deleted, you will discover that the system will complain of missing important O.S files and therefore will not be able to boot. Once the anti-virus have attack this programs, you will then discover that whenever you run those programs that run easily, they will be taking long before they will run. Once you see this, note that virus are already having their way on your system.
Accessing Disk Takes a long Time
Usually, the data disk that we sometimes want to install on our system contains executable files that always need the permission to access O.S files so that they can register the program which they represent into the folder that contains other programs. This folder is one of the major file that virus always look to attack because it takes them closer to the O.S files.

Now, once this software are inserted into the CD/DVD drive on our system, and the presence of those executive files have been detected by the virus, the y will now attack that file with all they’ve got that is why access the disk during their attack makes the dis takes longer time before it can be accessed.
*Note: This only applies to a situation whereby the disk you want to read is a clean one. That is, it hasn’t scratched.
Files Disappear and File with Strange Name Appear
After your files have been successfully attacked by virus, as a result of the virus destroying your files, the files will one after the other begins to disappear. You might even be making use of that particular file and then you suddenly discover that the file will just change from what it used to be to something you have never seen before. Once you see this, know fully well that there is virus on your system.
Executable Files Change in Size
Once the virus has the access to attack the executable files on our system (mostly those people that like storing software on their system) you will discover that they will change in size and either the size increase abnormally or it reduce. This is because the main file that is very important for this executable file has been taken over by the virus. Once this is done, the virus then has all authority to alter the size of these files.
If this situation has not gotten out of hands, you can easily use a good anti-virus to scan your system and once the anti-virus have discovered the virus, you can ask the anti-virus to repair those files. But in a situation whereby important O.S file has been tampered with (that is the out of hand situation), the only and best solution is to reload (reinstall) the operating system.
