Trojans and Downloaders are taking over my laptop!

Hello everyone,
I've been having problems with trojans and dowloaders lately, and now they seem to take over my pc.
It all started like this: the connection to the Internet suddenly stopped, then I noticed that Stop Dialer had been turned off. I tried to start the program again, before reconnecting, but it kept turning off.
After I reconnected to the net a window appeares, asking whether I wanted to install [bleep] Downloader. I pressed Ctrl-Alt-Del and stopped the corresponding Internet browser, and the window disappeared.
After that I noticed a small square (light green) with a green D on it, in the tray, in the right corner.
Until now, whwnever there was a threat (indicated by AVG), but not a virus, I would restore the system to a previous point and everything would be fine.
I did a system restore this time, too, and for a while everything was ok, then one night I heard the noise of the computer trying to connect to the Internet (like the old 56k modems did), and then a registered voice (from the phone company), which said "the user is not abilited for this kind of calls). Luckily enought, my phone plan blocks access to certain phone numbers.
I was worried, because I was workins on the pc and I didnět like it to do things on its own :-(
Another system restore, another short time of peace, then I found a link on the desktop to a certain "Instant Access". I right-clicked on it and looked at the properties, I saw it linked to a program in the Temp files. The link had appeared while I was working on the pc.
Of course, another system restore... and I started to look for advice on the Internet.
I found your site and followed the advice for what to do before posting.
Here are the results:

1 .ATF cleaner - done
2. creating new restore point, flushing all old: done
3. AVG Anti-Spyware:

InstantBuzz is a bar that I have installed, they serve ads on a bar and in exchange my ads are seen on other people's bars. I thought it wasn't something dangerous.

I have also performed the Ewido scan online, and each time I perform it I get a message from AVG antivirus: that there is a trojan downloader in C:\:eND.exe, when I tell it to heal or destroy it anwers: Access denied.
But when I go under C:\ etc. I don't find the file (even if I can see all the system files).
4. Super Anti Spyware - done. Here is the log:

I have deleted the files containing alexa tootlbar and profitsoftware, but I don't know what the pskill.exe might be.

6. AVG antivirus: done
it says there are no infected files on my pc, it only says that C:\windows\system32\kernel32.dll and :\windows\system32\shell32.dll were modified
I have looked at the properties of these files and the last modification was done in 2004, so maybe it has nothing to do with it.

By the way, each time I found the downloader before, I would perform an AVG scan (but I don't know how to save the log) and it found all kind of .exe files under C:\System Volume Information\restore (numbers).

As my laptop heats very much, it took some days to perform all the scans.
Before performing the last one (the AVG which didn't find anything), the computer started to behave strangely again.
When on the Internet, a window appeared, telling me the connection was interrupted (it was the first time a window announced me about that, the other time the connection would just interrupt).
I pressed Ctrl-Alt-Del, couldn't sse anything suspect, so I assumed it was legitimate. As it wouldn't go away, I clicked on the x.
Then I restarted Stop Dialer (which had shut down) and reconnected to the Internet (making sure StopDialer showed the ADSL connection used by me).
Then I re-discovered the infamous green square and a link to Instant Access.
I performed a Ccleaned (I use it frequently), then I had to go out and turned off the PC.
When I started the pc again, the AVG antivirus, the Norton Antivirus, Super Anti Spyware, Stop Dialer were not there. In the end I went to the Programs folder and started the AVG program, which told me the computer is clean.
I also opened Norton, and I saw that the Internet Security was de-activated, I clicked many times on Activate but it wouldn't activate.
I know I shouldn't be supposed to have 2 antivirus programs, Norton came with the computer, I like the fact it lets me know when a program tries to connect to the Internet (I have caught some naughty things like this), I didn't renew the subscription, but I kept it. (I'm a little bit angry with Norton, as it let me open some files and only after told me they were infected.) Then I installed AVG and we've been very happy together... until now (I never had any problems with both Norton and AVG running.).
By the way, now AVG can't update.
The conclusion is that in the last few hours these "things", whatever they are, decided which program's don't start at startup anymore, and I started to be a little afraid. Hope to be able to turn on the pc tomorrow morning.
By the way, it's a Packard Bell laptop, I also have SP2 (I didn't download all the updates, for instance those for Windows Media player, which I don't use).

Sorry for "talking" so much, I don't know which are the useful clues and which not.
What can it be and what can I do?
Please help a desperate computer mommy
Thank you very much,
