I noticed a persistent ad of ReImage in my Firefox browser, so I ran Malwarebytes anti-malware program which removed some 70 files and keys of PUP.Optional.Wajam to quarantaine.
After this my Firefox does not come up, there is only a background process in the taskmanager. I installed Chrome which only gives errors like ERR_CONNECTION_RESET, only Edge works ok.
I switched from wifi to cable connection, no result. I adjusted the MTU for this adapter, no result.
Can you please help me out to get my Firefox working again?
