Okay, some context. I love my computer and what I can do with it, but since I have a low level of computer knowledge I tend to have a level of trust in my computer that is about the same level of trust Stalin had for his officials, e.g. not bloody much. So, I do get a little paranoid sometimes with it (although, I would cite the Curse of the Jade Scorpion with regard to paranoia's occasional usefulness "You know what they call paranoid people like you?" "Yeah, perceptive!"). Anyways, something came up recently and I wanted to get some professional opinions about it, who might be able to tell me if I'm just being paranoid or if there might be something worth digging into.
To begin with, I'm running Windows XP SP3. Recently I've been reinstalling things on my computer after I reinstalled windows following a stupid mistake that corrupted a pile of the files when my computer accidentally shut down.
Anyways, I was uninstalling Norton 360 and reinstalling Norton Antivirus (long story short, I was mixed up which version I actually had bought before and had been using Norton 360 on trial up until I finally got around to getting my product key, when I realized that I had the other program). Upon a reboot, I noticed that my firewall (standard windows firewall) was down and their were new updates available from Windows Automatic Updates. I was a little suspicious, so after turning the firewall back on, I started a virus scan with Norton and decided to check each update after the scan to see if they were kosher.
What I had forgotten was that after my reinstall of Windows, I had left the updates to automatic install, rather than giving me notification of available updates. So, you can imagine my amusement when I came back to find my computer reboot with all updates installed. Swearing bloody vengeance, I then proceeded to double check the install log, which indicated that all installations were kosher when cross-reference with Microsoft. I then ran a full system scan with Norton, finding nothing. I then ran a full system scan with Panda Activescan 2.0, finding nothing. I then ran a full system scan with SUPERAntiSpyware, finding nothing.
So, have I done all the necessary steps to make sure that the firewall thing was just an error and not something more malicious, or might there be something to my e-paranoia and are there further steps I should take to ensure my computer is safe?
