My system is running Windows XP (SP3) and I desperately need some advice re GMER.... Over this past weekend I had a bootup issue but I was able to boot the system into safe-mode, reverted to the last known working configuration (or whatever) and when I rebooted the system all seemed well. Yesteday I had the same bootup issue, so when I finally got Windows running I decided to run a chkdsk /f which found (and corrected) quite a few errors. I thought that was probably the cause of my bootup problems until today when I again had a bootup issue! So I decided to do a full system scan with my Norton AV - which reported my system was 100% clean. Having read about rootkit activity, I just downloaded GMER and ran it. GMER immediately reported that a rootkit was likely on my system and when I let it do a scan it found 5 Red (infected) items, 3 Norton (NAV) services and 2 NAV update files!!! Now I'm bewildered and don't know if I should believe GMER and allow it to disable/delete those NAV items or not - what do you think I should do?
