Let me first state I'm not the most technically inclined person, so please understand if I don't "get it" at first.
I received this error when I first turned on my computer yesterday, and it gave me to option "OK" and "Cancel". Neither of these options seemed to work. Next, I restarted it, going in with a F8 "Last know configuration". This seemed to let me get in and I updated my Trend Micro virus protection and restarted. From here I was able to log in and ran the virus protection and received and deleted 2 Adware programs. Because this happened on my computer at home I can't tell you the exact name of the programs which I deleted, but one had the name which many people have been discussing in other threads (started with a "V").
I thought everything was fixed, restarted the computer, and logged in. However no matter which way I log in (regular, safe mode, or last know configuration) the desktop comes up regularly but it reloads every five seconds or so. I spoke to Dell last night regarding this Inspiron laptop, and was told I would have to reload my entire computer. I would like to avoid this if possible.
