Read the instructions given on the page from which you are downloading the programs. Some of them might tell you to disable your AV app, but before I did that I would be certain of the reputation of whoever is offering the program - that it was from a well known reputable source.
Here are some programs that you should install to keep your computer protected against malware (in addition to whatever you choose to be your anti-virus program)
I suggest that you also replace the Windows firewall with Zonealarm or one of the other well known freeware firewalls as the Windows firewall only protects you from incoming threats and not any outgoing malware at all. (Trojans, phonehomes, dialers, etc)
Free Zone Alarm SE: http://www.lavasoftusa.com/support/download/http://www.zonelabs.com/store/content/comp...;NONE?lid=ho_za
You must have the firewall active before you access the internet so leave the Windows firewall active until you download and activate a better one.
Since the AV program that came with your computer is probably a limited free trial you might want to replace it with AVG (freeware) or the firewall of your choice.Antivirus programs - freeware
(you can only use one resident anti-virus program on your computer. More than one will conflict)

(You can run as many of these as you wish. Generally there is no conflict between these and you should always run several)

. Run it, click Search for Updates, then click Scan.
CWShredder (the best for CWS coolwebsearch malicious malware renoval)
CW Shredder removes some variants of spyware known as the Coolwebsearch Trojan. The Trojan takes advantage of a flaw in a key component of Windows -- Microsoft's version of the Java Virtual Machine -- to install itself via popups often found on porn and illegal software (a.k.a. "warez") sites. Run CWShredder after installing, and have it look for updates. Then click the "Fix" button, and the program will both scan and fix any problems it finds. If your system does not have this kind of spyware, it will give you the good news.
