I have a router that I suspect may have delivered malware to my Acer Nitro5 laptop, which could be persistent somewhere other than the HDD.
I was using bitdefender which did not help at all, and once connected to the router, the laptop froze, and subsequently Firefox disappeared completely after restart, no longer installed at all, and icons started turning into white blocks.
I installed a backup SSD, which used to work perfectly on this laptop, and it threw strange errors, like Unable to Read Firefox profile, and Unable to Log into Windows, even after being logged in.
After a shutdown, battery disconnect, and startup again, I got a blue screen, so I went on to a 3rd SSD which seems to run fine now. The question is, what's the best action at this point? Should I connect it to Internet to get ESET?, .. if there is still some malware remaining, it would be a good idea to be separated from the Internet to avoid downloading extra malware.
Is there an offline ESET scanner I should use? Any help is appreciated. I'll be switching to ESET, as bitdefender did not help at all.
thanks
