First off, ad-aware is awesome, spybot is good, but just not as awesome as ad-aware. Second, these are NOT anti-virus programs. They are anti-spyware and anti-adware programs, these are completely different things here. But alot of viruses, including trojans, infect your PC thru spyware and adware. So, you need an awesome AV program on top of ad-aware. The ad-aware to find the spyware and remove it, the AV to remove the infections contracted by spyware. The jury is out on the best AV. My only opinion on these is that McAfee suc*s!! I use Norton's corporate edition gold, it is awesome!! Someone up here posted about majorgeeks.com. I use that site alot for new updates. I just updated tonight, re-scanned, and it picked up the spybot worm AGAIN! It found it before, but I had to re-boot in safe mode, go into registry edit and manually remove the worm. But, somehow a different version of the worm now has found its way back on here, and I got to go thru all that reg edit again
And the reason why you have to log in each time you re-enter is because you do not have cookies enabled, which is a good thing. But, if you want to enable cookies, I don't see why you should want to, but if you do, go to the tools menu, click internet options, then click privacy, and set it up to what you want.
Hope this helps.........good luck!
