So he calls me and says he has this spyware (doubleclick) that keeps reappearing. I get him to install UltraVNC so I can get a look at it from here, but his ports are closed so I can't connect to him. Not having anything better to do, I go out there.
I get him to show it to me, and there, scanning with Spybot Search & Destroy is the result of a tracking cookie from doubleclick.net. I then configured IE to block third-party cookies, and added AdBlock to Firefox (he uses both).
After that, we had fun times talking about various stuff, listening to music. I showed off the wonders of VNC connecting to my home computers, and installed mIRC and made it SSL-capable so he can talk to me on IRC. Played Lazy Jones on the C64 emulator on his XBox just to see that it worked. Finally, part to compensate me for my time, partly because I don't really have any more money than I need to pay for my upcoming surgery, we went grocery shopping and he paid for my stuff.
I wish people would realize that they don't need to have computer issues to call me and get me to hang out with them. I enjoyed today, I really did, but the original reason for the visit was just stupid.
