Ok so i had a spyware virus a few months ago and came on here to sort it out, but it seems a bit of it remained on my hardrive and has come back with a vengance. I have this piece of spyware that keeps popping up porn ads with sound and video, and fake anti-virus ads where the only way to get rid of them is to restart the computer. Please help, i forgot all the techniques to get rid of it so i think i will have to start from scratch? Also it doesn't let me do cntrl alt delete

Try malwarebytes first if that does not work ccleaner, unhackme and combofix are others

Do NOT use combofix unless you are given instructions on it's use.

try noobkiller which is searcheable on google.

Please do the following:
Please Download ATF-Cleaner.exe by Atribune(Windows XP, 2K, 2003 & Vista ONLY)

• You can put ATF-Cleaner on your Desktop for easy access.
RUN ATF-Cleaner.exe.

-- Click on ATF-Cleaner to run it
-- Where it says Select Files To Delete, Check the Select All Option
-- Click Empty Selected > OK

If you use Firefox browser, do this also:

* Click Firefox at the top and choose Select All from the list.
* Click the Empty Selected button.
* NOTE : If you would like to keep your saved passwords, click No at the prompt.

Please download Malwarebytes' Anti-Malware (MBA-M) to your Desktop.

Reboot the computer.

Run the ESET Online Scanner and attach the ScanLog with your post for assistance.

Reboot the computer

Download HiJackThis. Run a Full System Scan. Save the log.
Post back here with the MBA-M log, the ESET log and the HJT log.

try noobkiller which is searcheable on google.

I would advise against this. The program is flagged as malware at some sites. Go with conventional programs and those most commonly recommended here and most other well known and reputable computer help sites.

thanks for the help guys, i have a problem with the link for ATF-Cleaner.exe, it just loads a blank page

That is a direct link to the executable file. Don't you get a box like that shown in my attachment? You have to give it time to pop up, then click save and it will download to your desktop or where ever you tell it to save. Desktop is the easiest. All the download pages available are going to give you the same thing, the executable file.
Try here and here.
If that doesn't work then try CCleaner though it too is going to pop up the executable file.
