My computer has been acting up ever since i downloaded a dodgey crack for a PC optimizing program off the internet ... (which was really stupid)

I'm not sure whether that was the reason but i had to install it and it may have infected my registry ... I was actually trying to speed up my PC.

I had defragged my system, virus scanned, spyware scaned, 'CCleaner' scanned it and then ...

A few days after that my computer started slowing down dramatically it took 20mins to start up, hours to simply browse folders and then i realised that my CPU usage was at 100%!

I deleted all recently added programs and files i could think of (including the cracks) and it didn't help ... ran more scans, which took 19hrs for a scan that would usually take 3hrs. So i decided to back up my documents and all personal files (which took 2 days) and reformat ...

I had heard that vista should be reformatted once a year anyway, so firstly i did re-install of the system on top the old one ( which didnt affect the constant 100% CPU usage). So i had boot from the disk and format the main disk. I installed windows once more and there was no difference.

And here i am ...

Now i have had my lappy for 1.5 years now its battery needs to be replaced (coz it keeps flashing a red light at me) and its has overheated in the past (problem fixed with lappy stand now)

I've used process explorer and it is system idle that is boosting the CPU usage up, i have read the reasons for why it happens, but i don't fully understand why it started up after 1.5 years of perfect lappy performance.

After reformat CPU isnt always 100% but is always above 50% (with standard vista apps, i haven't installed anything on it yet) and my OS starts lagging after 1hr of use.

Lappy Specs:

Windows Vista Home Premium
Intel Core 2 Duo T7500 @ 2.2GHz
3.00GB RAM
NVIDIA GeForce 8600M GT 256MB

I have a HIJACK THIS report too if needed

Please help

You have a Hijuack This log posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
