PC maintenance

During the weekend I always run the following programs to keep my PC clean:
virus: AVG
spyware: Ad-Aware, AVG
registry: regvac
cache: ccleaner

McAfee and Defender are running on a daily basis, so in a way AVG should be redundant.

I also clean and defragment the HD, and check for any TradeBullet and TWS updates. Just installed TradeBullet build 527 and TWS build 872.6.
