Handling the consequences of harmful PC malware
Handling the consequences of harmful PC malware
Well, it turned out something unusual with my laptop. The Windows Defender scan didn’t find anything, but Malwarebytes (free version) caught a few suspicious programs and removed them, marking them as Trojan.FakeGoogle and Trojan.HijackLoader. I’m sending this info from another machine. It seems the threat likely came from a questionable download for an indie game—probably because I was too relaxed after making a mistake. The malware might have taken control of my accounts or stolen my passwords, even though I use a password manager. I received warnings about suspicious login attempts and had some cryptocurrency taken from a wallet app I installed. After resetting passwords and clearing browser data, cookies, and cookies, I removed the password manager extension. So far, my Windows Defender and Malwarebytes scans show no signs of trouble. I’m planning an ESET scan now. The laptop seems to be functioning normally so far. Regarding my accounts: reset your passwords and ensure two-factor authentication is active. It’s okay to keep using a password manager once you’ve set a strong master password. As for how the malware reached my system—possibly through a browser or remote access method.
Following the infection and multiple account issues, I wouldn't feel confident with this PC. I might perform a complete Windows reinstall... But perhaps I'm being too careful? It seems almost certain to eliminate any virus or malware traces. Unless it's a Bootkit or BIOS malware, of course.
Sure, perform a complete system reset. It may be bothersome, but it’s a far better choice than proceeding without confirming the malware is fully removed.
I believed it could be the optimal choice, but I wanted to verify if it was excessive. Therefore, I plan to reinstall Windows from a flash drive (using another machine to build the installer). I think I shouldn’t move any data off the compromised device. Fortunately, I just completed a recent backup.
It's not too much effort. Your important information is at risk here. It takes a while, but it's worth it for your security. If possible, download from another device. Avoid using or moving files from the infected machine. It should be okay with just documents or photos, though you'll always worry about it.
Use a trusted anti-malware tool to scan and eliminate the Bootkit/BIOS threat. Follow manufacturer guidelines for firmware removal if necessary.
When you reinstall Windows from a flash drive, it’s best to clear all partitions on the target disk except for the one designated as boot drive. This helps avoid conflicts and ensures a clean setup. Regarding the second SSD, formatting it is recommended if you plan to use it for storage, as it creates a fresh environment.
