thing that hits our mind when we say the computer is virus. There is a virus
spread all over the internet waiting to damage your computer or leak data the
instant you click on them.
But there
are common ones which you can identify easily. And then comes the ones that are
known for creating heavy damages. For instance, Doom which affected in 2004 was
the most expensive virus as it led to the destruction of files and software
worth 38.5 billion. So going for tech support like Norton

most common yet dangerous viri which exploit your PC or laptop is as follows
Resident virus

considered to be the most dangerous type. They affect computer by automatically
installing them while you are not aware. We categorize them into two. The slow
infectors and the fast infectors. The slow investors are difficult to detect as
the make their destroying remotely hiding from our view. The other one is
really fast in destroying making it easy for us to spot.
Polymorphic virus

virus is used to changing their binary pattern constantly making the detection
process difficult. They are extremely difficult to detect as the anti-virus
programmes think that they are any other common file because of their nature.
So you are going to have a really bad time if you are having to deal with this.
Boot sector virus
Just like
its friends it has its own list of damage records. It's ultimate aim as soon as
reaching your computer would be to infect and destroy master boot record. In
some cases, the situations are worse demanding a full computer reformat. Though
their impact has been reduced in recent times owing to various developments,
they still happen to pose a great challenge.
Direct action virus
This kind of
virus happens to be the less dangerous one when compared to its fellows. They
attack your computer not by downloading themselves like others but by attaching
to a file. They search for other files to spread. They are not as destructive
as others. They don't end up destroying everything. They are also easy to
remove as they don't hide as others.
Overwrite virus
These are
the most common viruses owing its existence right from 2000. They are also
considerably less dangerous than their counterparts. Removing them is also easy
at the same time. They destroy the contents of the file they have attacked or
have attached to. This will require us to delete the file permanently if we
want to get rid of them.
The above
are some of the common types of virus that infects your device. There are cases
where the entire system including your anti-malware gets infected. Getting a
professional help like Norton internet security contact UK is the
right choice to make under such circumstance. But you can also treat them by
