pc-on-internet pop ups won't go away

i ran all the basic scans and cleaning procedures, and i still have these pop ups that ask me to down load some antispyware program on a screen made to look like a vista screen. the logs are attached. this all began about three days ago, the only new thing i can remember doing on my computer is using pandora, the music genome radio site, but i have many friends who have used this without problems, so i don't think that was it. also, a friend sent me a picture that i didn't scan before opening, but i was expecting it, but who knows, not me!

i attached the mbam and sas logs, but it keeps telling me the me the mgtools zip folder is invalid

 

i meant the file. the one i am trying to attach reads c:/mgtools/zip.exe

its the only mgtools zip file i see, i don't know what i'm doing wrong, but obviously its something.

 

ok, so i found the mglogs.zip folder, but i see no .zip file. i'm attaching the one labeled hijack this. if you need one of the others, or if i've done something wrong still, let me know

 

sorry, i figured out what i was doing wrong. hopefully this is the right folder.

ps. i think its rather obvious i don't know much about computers, so please be patient, and thanks for helping.

pps the pop-ups are happening more frequently now, it used to be like once every 5 or so pages and now its almost every time i open a new tab or window. when i run the super anti spyware, its better for a little while, but then it gets worse (and it seems to get worse quicker now)

 

i did everything you said to, but i had some error messages. i assume the errors for avenger will be in the log, but when i tried to delete the c:\windows\temp folders and files, i couldn't delete JET7944.tmp because it was in use, even though all programs were closed, and i couldn't delete ~DF1469.tmp from c:\users...\temp for the same reason. also, whenever i download anything, it automatically goes to my desktop and i don't know how to change that, for the mgtools.exe. could you please let me know what i need to do for that? i am running vista if that makes any difference. i've attached the avenger log as requested, though i couldn't get it to upload from the c:\avenger.txt, so i saved it to the desktop and uploaded it from there. i can see the file in the upload manager screen, but it won't let me upload it. i don't understand why?

things are always better after i run cc cleaner, but the problem will usually return after being online for a bit. i don't go to any unusual websites, i mainly just check my email, look on craigslist, and check my myspace. i mean, i do your basic surfing, but i don't dl games or look at videos (occasionally on youtube) or visit porn sites or anything like that. i've tried to pay attention to see if its after visiting one particular site that the problem returns, but as far as i can tell, its just random. all the pop ups have pc-on-internet in their addresses, or tracking something. i would tell you exactly what it is, but my history was deleted with cc cleaner. other than the pop-ups, my computer seems to be working fine, maybe a teensy bit slower, but i don't run any major programs, itunes and microsoft word are about it, so i don't know if i would even notice if it was slower. i use either mozilla or opera as a browser, i only use ie for netflix watchitnow.
