Piriform Speccy is a Free Hardware Information Tool

Posted by Angel Luis On July - 1 - 2010Comments Off on Piriform Speccy is a Free Hardware Information Tool

Windows 7 HWHardware is by far the ugliest part of a computer because information on this subject is obscure and difficult to find.

For example, imagine you need to know what kind of RAM is installed or whether or not you have free slots on your motherboard: you’ll have a hard time finding an upgrade. You need a free slot to install new RAM, and you may need to use the same type of RAM on all slots.

Windows 7 Security OkThe problems you must face using an Antivirus are not always obvious. By not properly uninstalling an antivirus programs, you can experience system instabilities.

It is not unusual that you find problems when installing a new antivirus program due to traces of the older one.

The first choice you should use is the uninstaller that comes with the software. But if something happens on the process the following list can solve your problems:


Panda has created an uninstall program for every product, so select the proper one:

Panda Antivirus, Firewall 2007 Uninstall Utility

Panda Antivirus, Firewall 2008 Uninstall Utility

Panda Antivirus, Firewall 2009 Uninstall Utility

Panda Antivirus, Firewall 2010 Uninstall Utility


Removal Tool for Kaspersky Lab Products

This removal tool can uninstall all versions of Kaspersky Antivirus and Internet Security but under 64 bit operating systems versions 6 and 7 of the products.


For reasons that I don’t understand, Norton Antivirus leaves a lot of  traces even if you uninstall it using the default uninstaller.

Norton Removal Tool


F-secure has created an extensive page about how to removal its antivirus:

Advanced F-Secure product removal

There is an uninstaller tool but F-secure only recommends it as a last resort.


Bitdefender Uninstall Tool


Avg Remover


Avast Uninstall Utility


How to uninstall or reinstall supported McAfee consumer products using the McAfee Consumer Products Removal tool
