I use Avast instead of AVG. Updates automatically and AVG suddenly did loads of changes to theirs which slowed my PC down no end. Then I have Spybot, Spyware Blaster and Zone alarm basic.
For cleaning I use CCleaner first then Disk Cleanup, the Registry Mechanic.
For Defrag I use SmartDefrag because its really quick, then normal defrag to do the bits that SmartDefrag missed.
Utorrent is cool and isohunt website is easy to use.
GoogleChrome as a browser with IE as a backup for problems.
AuctionSentryDeluxe for ebay sniping
For DVDs I use MagicISO, DaemonLite, DVDShrink, DVD Decypter, ConvertXtoDVD
With pics I don't mess with them at all. I just reduce them in IrfanView.
I have Office 2007 but wish I hadn't. 97-2003 was much easier to use. Usual change for change's sake from MS!!!
Others : WinZip, WinRar, ScreengrabPro.
