Here are some on demand scanners, take your pick:
– Kaspersky Virus Removal Tool
– Kaspersky TDSSKiller
– Emsisoft Emergency Kit
– ESET Online Scanner
– Norton Power Eraser
– Comodo Cleaning Essentials
– Avira PC Cleaner
– Zemana AntiMalware
– RogueKiller (and then click Portable 64 bits)
Most of those links are direct to the .exe or .zip, so feel free to google for them instead if you don’t want to trust the random guy on the web (promise I won’t be offended).
All of them are free, although some may have ‘premium trials’ that you can just decline or deactivate. Most (not Zemana and Malwarebytes) are portable, so there’s nothing to install, you just run the scan and delete it after if you want.
I’d recommend running the first 5 and RogueKiller. After, run HitmanPro, and if it comes back clean (tracking cookies can be ignored) then you’re likely all good.
