i have recently come across these services on my vista machine. as i was trimming/checking the auto starts and setting some things to manual, something i do quite regularly is check that they have remained on manual .. whilst checking i came across these 4 services .. i hadnt noticed them before and 99% sure they appeared about 2 months ago. AHZQZXQN Disabled Local System TQFPCWYBNJE Disabled Local System UHWX Disabled Local System FAVYPXOB Disabled Local System i have tried all kinds of search engines but cannot locate any trace of them .. nor can i find out any details from my machine.. does anyone else have any uniquely named services on their machines similar please, they were set to manual so i disabled them 1 at a time for about a week each with no detrimental effects .. so i then set all to disabled and still no problem . my fear is i may have picked up a rootkit.. i only run nod32 and windows firewall .. however i have a small army of on-line antispyware and virus scanners to hand if needed. they found nothing but a few FPs same as the freebie and several free trial AS/s. any ideas anyone.
