Much trouble after removing adware istbar virus

Question

I do alot of research on my own and have had no luck w\posts or google sites that give instr.   It seems every time I turn a corner I get stopped again.  I can research the sites I've marked to let other users know where I have been and what I tried.         After nortons found and removed the adware istbar virus from my laptop (old post) many new problems since. Cant defrag or get live updates for nortons or at the dell checkup site cant download the new updates they tell me to. live update is error 1803, defrag window appears but nothing happens. PS, I have spybot and adaware and adwatch, But recently removed AVG free and spywareblaster thinking they were stopping or binding my laptop. Also have my windows firewall shut off and only use the norton firewall.    Any takers?

ok, don't flame me but with all those issues I suspect you'd benefit from a fresh install or a dell system restore if you laptop came with it installed.

Hey thanks for the reply.  One other problem I didnt mention was that it seems the virus nuked all my restore points.  A friend helped me use the OS disk to try to do a fix but we ended up just reloading the whole XP home edition.  Did we do something wrong?  I really dont want to dell PC restore if at all possible + being new at this it would be nice figure out what went wrong.  I'd feel alot better knowing I can fix rather than retreat.   Also is it true that in most cases of removing a virus/trojan that sys res might need to be shut off?  thanks again

Viruses can do some nasty things to computers and so can Norton. My suggestion would be to start from scratch. Wipe the drive and reinstall Windows. I'm not sure what the virus you had actually did to your machine but it apears to have messed with some of the core files. Historically some of Norton's services use huge ammounts of memory and CPU time. I personnaly wouldn't use their firewall and would consider just using the MS one installed with SP2...it's already on there, you might as well use that one. As far as AV software Norton's ok but you might run into the same speed issues and 100% CPU useage.

As far as fixing your OS... at this point I wouldn't even bother. You attempted to repair using the OS disk and that didn't work. Backup your data and start from scratch with a new build. Just make sure the data you back up isn't infected first.
