Tip & How-To about Computers & Internet
The Computer Virus.
Firstly lets understand 1 thing, Virus, Worms, Trojans, Malware, Adware, Spyware etc are different things!!.
A Virus ,, think of it as a program set to do malicious things without your consent.
Antivirus is used to remove a virus. There are different types of antivrus and people rate them differently. Some prefer this ,, some that,, I prefer AVG cause its free :). Any way to the point of this tip.!!
Here is what you dont know about an anti virus. This program will only detect a virus it knows about,, that's why u need regular updates!!! If it doesn't know a virus exist It will never find it. So any antivirus is only as good as it's updates!!.
How does it remove a virus ?
Simple! A virus usually alters the registry, renames a few files, injects it self in others and copies its own files to replace those it renamed. It Keeps itself in memrory and limits the users access to the computer.
The antivirus update contains the checksum of the virus so the antivirus app can detect it. Once found ,, the update also contains info on what the virus does ,, so the antivirus undoes it!..]
There it is quite simple. Remember your antivirus is only as good as it's updates!!
