Hi, I've recently bought a new computer, but now on start up it keeps bringing up the error message "Error loading C:/windows/system 32/citoriaj.dll, the specified module could not be found". Does anyone have any advice towards finding a solution?!

This sort of error can be caused by a few things including uninstalling software or running a disk or registry cleaner inadvertantly.
Usually you can replace lost .dll files but i cant seem to find this particular one anywhere and i am not familiar with it.

I guess this leaves you with a couple of choices,
(a) You can perform a system restore if you have it activated in windows or,

(b) You can boot from your install disc and perform a repair install of windows.

Regards

I do use a program called reg cleaner, but thats only really to clean up unnecesary programs on startup. I'm sure I can do the system restore, but not too sure about the other option you offered.
I think to break the question down, is it going to do my computer harm? Presumably if you haven't heard of it it isn't going to be a vital windows component, so do I need to worry about it?

If it causing problems with your system operation then i guess you need to fix it.
If its not bothering you.....well its up to you!

Follow the directions given from the links at the bottom of my post and no harm will come to your system (all data will remain intact)

Be careful with registry cleaners because if you go to hard, you can leave your system inoperable.
For general cleaning of old temp files or reg entries left over from unistalled softs i prefer to use an app called CCleaner (its free).
In all the years of operation it has never caused an issue and works a treat!

Good Luck!

Just as a word of caution~~Spyware programs usually encode dll's on your cpu. If you have a spyware removal program, try running it and see if points out this file. I would hate for you not to fix it, and it turns out being sypware....Good luck!

mmmm.....lol!

I think you mean the registry!

I think I've found out the problem- my computer seems to be infected with virtumonde. I've repeatedly deleted it- I run AVG, Spybot and AdAware normally, and both of them have deleted it several times. plus I have run several programs- Virtumondebegone and Vundofix, but I can't seem to get rid of it for good. Any advice?
