Hello, I really need your help and I was hoping someone here could help me.
Few days ago, my antivirus's trial period expired so I wanted either to trial reset it(I know I shouldn't, cause even if I don't really have money for the license, there are some free ones,but... oh well...) or find on some online shop - some cheaper license, instead of buying from the official site. Anyway, I tried to trial reset it, and me being stupid and at that time(after long time of searching) almost without hope - well I downloaded the first program i found(even though it was clearly one of those scammy ones) and then the catastrophe happened.
It's quite ironic, if u think about it.
Long story short - I downloaded something that seems like malware and I can't gett all of it away.
I had Bitdefender Total Security 2017 and only in safe mode could I uninstall it. Before doing it, I couldn't even show the program's window cause it triggered an error.
The main thing that is currently happening - I can't install any antivirus software, since I get "Administrator forbid running this application. For further info contact administrator.". Other than that, it seems that I suceeded in removing some of that virus, although I am not sure.
In removing the virus and malware i followed: https://malwaretips.com/blogs/malware-removal-guide-for-windows/ and https://www.bleepingcomputer.com/forums/t/453087/i-have-a-virus-preventing-me-from-installing-antivirus-software/. Although from the second link, I didn't use aswMBR. Also, I followed instructions from the guy suggesting to use Windows Repair All-In-One from here https://www.bleepingcomputer.com/forums/t/575664/windows-security-option-and-bitdefender-keep-being-turned-off/. I tried some of the options in this program(for example repairing the discs, although for some reason the repair kepps getting stuck at the beggining at around 11-15% so i gave up that).
I am usng Windows 10 Home(64 bit operating system).
I'd be grateful if someone could help me with this, because currently I'm out of ideas.
