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

Kaspersky

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.
Norton
For reasons that I don’t understa nd, Norton Antivirus leaves a lot of traces even if you uninstall it using the default uninstaller.
F-secure
F-secure has created an extensive page about how to removal its antivirus:

The internet changes very quickly; for that reason, stepping back to the basics is very important. As you may know, the internet is no more than a collection of interconnected networks.
In this post I will show a list of basic network commands. Even if you haven’t used any of these before, it is useful to know they exist. As always, increasing your knowledge is the better way to achieve your goals.
To run these commands, open a command prompt:
These are Following Basic Commands you can use in Command Prompt
arp -a
This tool handles the resolution of a IP to a physical address. The command gives a list of IPs and physical addresses on your local network.
ipconfig /all
This is the main network tool. Using without parameters gives you basic information about your network. With the all parameters, a more detailed information about DNS, DHCP, and other network settings appears.
ipconfig /renew
This command renews the IP that a DHCP server has assigned to your computer. This is the command that Windows uses when it tells you that is trying to solve a problem with the network.
ipconfig /flushdns
Your computer has a table with the names of computers and their corresponding IP addresses. This command will remove all the entries on that table. It’s very useful if you change your DNS servers.
ipconfig /displaydns
This command display the content of the table we were talking before.
netstat -nab
With this basic command, you can know every open port on your computer and the executable that has the port opened. In Windows 7 this command needs Administration rights (Click Start, type cmd, right click cmd.exe and click Run as administrator.)
netstat -r
Display the routing table.
ping <ip-addr>
The easiest way to know if one of your computers is connected to the network.
tracert
Informs about the route to a remote host. The problem about tracert is that this uses a specific port that can be blocked in the route.
If you want to know if you can establish a connection between you and a router port use:
pathping
A better version of tracert that gives you statics about packet lost and latency.
nslookup
With this tool you can check your DNS servers. For example, imagine you are experiencing a problem with your current DNS and it cannot resolve the address www.mintywhite.com. You can test it with nslookup and use other DNS servers to try to resolve the address.
This program can inform about a PC name given his IP address.
