Dear Broni and All, I have completed all steps, and ran the security programmes recommended in this thread: http://www.techspot.com/community/topics/keep-getting-stupid-shopping-malware-installed.208648/ However, I am still getting pop-ups and adware related problems, which means that the underlying problem has not been resolved. These are the programmes that I have run (today, 18/05/2015): -RogueKiller -Mbar -AdwCleaner (it removed NickelBlock, AllCheeiaPPPriCe, DowwnSaave, SaVieNeewaApupoz) -Junkware Remover -Farbar Recovery Tool -Farbar Security Scanner -Security Check -Tempfile Cleaner I am currently running Sophos. My laptop runs Windows 8.1, and Combofix does not support it. The antivirus that I have is Kaspersky (I previously had Microsoft Security Essential), and Windows Defender. The malware was not detected by a Kaspersky and Spybot full scan a few days ago. However, on the 26th of April, I manually uninstalled some adware, and then ran full scans, which showed nothing. As you can imagine, I don't think I have many options left, and formatting my laptop is a dreadful prospect. I was wondering if you could give me some advice. I have kept all logs of the security programmes that I've run. Thank you in advance, and looking forward to hearing from you.
