My friend...is an idiot

Alright, well, this is a mess (at least to me). I managed to get avira into his computer as well as A-squared. After running in safe mode, with system restore off (hope he did this right, i didnt see this part xD) he deleted over 200 objects in a-squared and about 7 trojans in avira. We booted back up in normal windows...and the problems begin...
A. After clicking on the account you wish to access, you sit through about ten minutes of clicking 'Access Deny' on avira denying a file with the end extension of .dll , this happens several times before aything shows up.

B. Computer is unimaginably slow, and runs on freezes more than anything.

C. Internet explorer randomly opens to a site offering 'Antivirus/spyware, protection'

D. Task manager will not open...it says this feature is disabled by admin.

E.A random times script (i think) error messages pop up titled...'FATAL ERROR!' and such...all telling you to download an antispyware update...

F. Was a program titled 'cool' that i deleted...dont know what it did...

Now i ask you , does anyone have any suggestions, and may i also state, we were going to attempt to work on a project...due monday, so this needs to be semi time efficient ...
if you even have the slightest clue whats wrong, let me know...my friend is also in the process of downloading (hopefully) CWS Shredder and Killbox...


ALL HELP APPRECIATED...
Thanks in advance


Also meant to say, this happened when the idiot downloaded Flash 8 crack from limewire in an attempt to get it for free -.-

 

One more thing (and thanks ), whenever you get into safe mode, you get the message of you have system restore off and yada yada, but after clicking it, you have ten seconds to find what you need, before it comes back again ? And the reason i said killbox was to maybe find the dll file manually, and delete it xDD

 

Ohh xDD, im sorry, but thanks for helping, he decided just to get windows reintalled...

 

I appreciate your help, I tried to tell him what to do..but ahhh, he didnt

 

Ok, thanks for all the help , will do.
