DavidR, glad to hear about using two mice. I just found a converter at NewEgg to plug in my PS2 mouse and keyboard from my old Dell I bought in 1998, which I still use, into a USB slot on my new Dell, hope they’re not too old and this works for backup. Last thing I need on my desk is three mice and keyboards instead of just two! 
I decided to reinstall the PC Tools Firewall (never used Comodo, I think that one is not yet ready for Vista). My mouse pointer and keyboard froze again after 5-10 minutes, like the last time. All those hours of fiddling with the Bluetooth connection paid off in that I was able to get it going again, reboot to safe mode and uninstall the firewall, yet again–all by myself ;D
I then decided it might not be a bluetooth problem. I remember a Belkin tech telling me that the Belkin firewall and any added firewall might conflict and I might lose connection, so I called Belkin and he said yes, that could be the problem. He was going to disable the Belkin firewall, but I said I didn’t want to do that. I’m under the impression you get more protection with both, even on the inbound. He then had me download a firmware upgrade for the router. I reinstalled PC Tools firewall and I am now back on the internet with no problem so far (I left all the settings as is for ‘normal’ (regular?) user for now. All fingers and toes crossed I don’t lose connection again! (I wonder why the tech wanted to disable the firewall rather than upgrade firmware…I guess I might find out the hard way if I wind up having more problems.)
BTW, I am WAY impressed with Belkin. I bought this $40 router at Walmart along with a $15 ethernet card (different brand) for my old Dell and put both computers on the router so I can use both on my broadband. I installed the ethernet card myself from directions in the box, and the router from the cd. They both pretty much installed and configured themselves, could not have been easier. PLUS, Belkin has 25/7 live telephone tech support for life. :o They really do have good phone support, not just claiming that, and very little wait time, too…
Tech, before I decided to reinstall PC Tool firewall, I took a look at my Vista Firewall and got confused from the very beginning, I don’t know if you can even enable just the inbound anymore. It says this firewall was supposed to be enabled by default at the factory, but on my computer the whole thing was disabled for some reason.
rhuds13, good advice about the code injection thing, thanks!
Spiritsongs, I have bookmarked all the rootkit sites you and DavidR posted, thanks!!
Well it has now been more than 2 1/2 hours since I reinstalled PC Tools firewall and I’m still good to go…Too early to uncross all the toes and fingers though…
thanks again all you guys!
