Need to Clean My Comp Badly

believe my comp has a worm filling it up as fast as it can. cant open system info, cant get tsg sysinfo to work, tried twice, and cant even open the document I made of system info, without having to unplug the comp. Time keeps changin back to 2006. Cant run misconfig, regedit or the thing hijack this told me to run. Comp scared me badly yesterday, so badly i turned it off for several hours and unplugged it. Tried to open a program under recently opened, and it said i couldnt because I wasnt the system administrator and it was read only. changed the read only somehow, and tried to delete the file. It started growing like crazy in size, so i uplugged the machine. Finally turned it back on, sure this thing would crash the comp. Went to CNET and downloaded COMODO Virus Scan, it found and removed 2 threats in a deep scan which took over an hour. My comp needs cleaned I know, when i finally get regedit open and its set to default because of size.
I now something is going on, but not sure what is killing this comp. I want to clean this comp so it takes twenty minutes to do a virus scan, but no clue how to do that. Know its a dell, running windows 7 Pro. also know the battery is low since comodo found several files saying that. Dont know if its even safe to go online, since opening my homepage (msn) somehow opens 20 MBplus from what CCleaner says. I run CCleaner several times a day but feel this comp needs a really deep clean at least, and think it has a worm since yesterday, when i downloaded flash from cnet, and everything went crazy. It put twenty things on my desktop I had to uninstall, and one wont go away no matter how many times I uninstall. Also found notepad orders not to let Java run, and make runescape shutdown on startup. Spending today working on cleaning the comp, but have to pick up my daughter at 3:20. Help if you can, or let me know if this can even be fixed. thanks

youtube downloader is the program that i keep uninstalling and it keeps coming back. Also have a website opening every time i open msn that should be gone, and hijack this cant find hosts file, and gives an error message about the registry somethin adding a value that doesnt exist and so its deleted.

 

Turning off the comp for two days, then back on (I HOPE) to check for a reply. Turning back off if no reply is there, checking back every day or two until someone replies.

 

my roommate managed to do a system restore to four days ago and that problem disappeared, YAY
