Written Review - What does Spyhunter do?
Emsisoft Emergency Kit and Zemana Antimalware free are both good and free.![]()
First I would make sure you have got rid of SpyHunter completely and then if you are downloading malware samples you need a Virtual Machine.
Since you have had an infection less than 3 months ago make sure your PC is clean
Add some extensions to Firefox such as uBlock Origin
thanks for your suggestion.As mentioned above consider a VM or at least www.sandboxie.com to create a virtualized environment when needed.
