Is there a virus in your PC?


Think your PC is infected

You and everyone for that matter will become more concerned
about the viruses or any other problem in the computer when
the performance of it has gone down. Few symptoms will be
missing files, corrupted files or the system becomes very
slow. This can be due to a virus or a hardware problem.

Best possible solution will be to consult your IT expert at
this point. But if no such person is there in the ranks,
there are some things you can do by your own.

You will need to use antivirus software to protect your computer and avoid viruses.

Execute the Malicious Software Removal Tool

All the viruses, worms and Trojan horses are altogether
considered as malicious software. They will disturb the
condition of the system. Windows malicious removal tool is
an integrated part in the windows operating system and it
comes free. It will detect most common malware programs and
disable them.

It is better to run the tool once in a while even if there
is no danger of a virus. It will check the memory and all
other storing devices for infections. If found the tool will
repair them back or delete the infected files. It will even
reverse the actions taken by malware programs. It will give
a report after the scan.

It is possible to run the tool online also. Otherwise you
can download it and install it to your computer. Update
files will be available in every second Tuesday of each

Keep updating and scanning

Malicious software removal tool can detect some well known
viruses only. It will not catch many other viruses in the
world. That is why it is pretty important to have an anti
virus software running as well. Anti virus software can
detect many more viruses affected.

Just having an anti virus software is also no use. It should
be updated with the most recent virus definitions. This can
be done online by going to the vendor`s web site. If
internet is not available, you can download from another
computer and bring it.

Another very important point to remember while running the
virus scan is to disable the system restore feature in
windows. System restore will have a backup of some files in
a specific folder to restore them back later when required.
This backup files might be infected once. Therefore it is
better to stop backing up to restore folder when running the
scan. This can be done by right clicking on the “my
computer” icon and then select “properties”. Select “system
restore” from there and check the box for “turn off system
restore for all drives”.

When running the scan there might be files that cannot be
cleaned. They have to be either quarantined or deleted. It
is important to scan all the removable drives as well for

Some more ways

There are some other methods also to diagnose the virus
infections on a computer.
  • Use another anti virus program
Sometimes the specific virus will not be detected by the
virus scanner you are using. It may be due to the
unavailability of the update definition. In order to
eliminate this it will be better to use another scanner.
Some anti virus programs can be even run online.
  • Keep track of network activities
Some virus attacks tend to do activities over the internet.
These types of attacks can be identified by keeping a track
of network activities. Windows XP enables the user to get
notifications while the data is transferred over the
internet. This can be enabled by adjusting the settings in
network connections in control panel.

If it is suspected or diagnosed for any virus attack, the
computer has to be disconnected from the internet and local
area network. Otherwise it will spread more. Then it can be
cleaned by a virus scanner or can be restored to an earlier
created restore point.
