A layered approach using dedicated aps is far better than any combo bloatware.Freeware AntiSpyware and Security ProgramsSoftware firewalls with freeware versions
(Run only one and disable the ineffective Windows XP firewall)
ZoneAlarm (freeware) V. 6.5.722http://www.download.com/ZoneAlarm/3000-10435_4-10039884.html
(you can have only one software firewall running. More than one will conflict)
Comodo firewall (freeware)http://www.personalfirewall.comodo.com/Antivirus programs - freeware
(you can only use one resident anti-virus program on your computer. More than one will conflict)
Avast Anti-virus freewarehttp://www.komando.com/bestshareware.aspAnti-malware freeware
The following freeware aps will detect and remove spyware/malware from your computer and in addition to your resident anti-virus program you should have several (if not all) of these installed (and used frequently - each may detect things that the others may not -always update them before you run them)
Set them to update automatically if applicable.
Run them from safe mode when applicable
(You can run as many of these as you wish. Generally there is no conflict between these and you should always run several since each may find malware that the others may not find)
Ad-Aware SE Personal - freeware http://fileforum.betanews.com/detail/Adawa...nal/965718306/1
Update – Aug 2006 - Spybot by default now ignores certain products such as New.Net and Sidestep for no good reason. New.Net compromises the WinSock stack by routing all your DNS queries through the NewDotNet.DLL. To enable detection go to "Settings", "Ignore products", "All products" Tab, right click on "Product", left-click on "Deselect all". http://www.safer-networking.org/en/index.html
Be sure to enable “Teatimer” which gives you realtime protection against malware invasion.
Microsoft Windows Defender
Windows Defender will give you an additional tool in your control panel named Software Explorer which is excellent for examining software installed on your computer, its startup menu, etc which will help you identify what it is.http://www.microsoft.com/athome/security/s...re/default.mspx
This also provides realtime protection.
