XP-SP3 : I think i have 2 separate problems here. The first one is a firefox problem about deleted bookmarks reappearing & each days history disappearing after a reboot. I'm working on that. Don't know if it has anything to do with the 2nd one, maybe. I delete programs that i've downloaded in docs & after a reboot, they magically reappear & files i save in docs since this started, disappear. Also, my desktop icons are being switched around after i've put them in order after a reboot. I use firefox 3.6.18 to download these programs, so it may have something to do with the programs reappearing in docs/downloads after a reboot, who knows. I have alot of security programs on here that are all compatible with each other. This isn't a malware problem either as i have run scans & nothing comes up. Malware/trojans try to steal info, not move your icons around & make files reappear. I just added memory 5 days ago from Crucial Memory, although i doubt that has anything to do with this. These problems just started a few days ago. I can't figure out whats going on. Never had these problems before. THANX for your time/help anyone.
