Lime wire Harmful to my computer!!

I recently had no choice but to uninstall lime wire as it has had numerous malicious effects on my computer.

The first most important issue is that it constantly automatically downloads files into my hared folder, and with having a fairly fast DSL connection and very little space left on my hard drive you can see what effect this will have on my computer, filling up the hard drive in no time at all.
I have recently uninstalled lime wire but this problem still exists and I know this problem is down to lime wire as it started when I installed it and I have no other program that is capable of downloading that amount of files onto my computer. I think this problem may be associated with the “ultra peer” function but disabling this has had no effect what so ever.

Secondly Since I installed lime wire the CTRL ALT DEL function does not work, I’m am not sure if this problem is associated with lime wire but I consider it highly likely as after I first started up lime wire all these problems came to light. If it is nothing to do with lime wire it self it is most likely off one of the thousands of files that lime wire has downloaded onto my computer against my will which could have easily been some sort of spy ware or harmful application.

Thirdly Lime wire continuously used to start it self up even after I configured the settings to prevent it to but yet it still did.

I have uninstalled this program using the add/remove function and deleted all the files I could find associated with lime wire but I have no success in regaining the CTRL ALT EL function or stopping lime wire downloading thousands of files onto my computer which are all about 800kb each which takes up a fair amount of hard drive space when it is all added up.

I find these problems to be harmful to my computer, very irritating and would like some solution to them as quickly as possible.
