Recently whenever I open Firefox I get a message in notification center. It's not always the same and it keeps changing. here is an example:
It's not always this. It gives other messages too and when I click it it sends me to phishing sites. I don't know how I got it.
Could someone please help me get rid of it?
I tried Clam antivirus but it found nothing.
In the last few days, my system has started popping up an Ubuntu default web-browser and making a request to nmcheck.gnome.org website and immediately shutting off.
Since this happened, I cannot run system updates.
Also, I am a php developer and cannot run composer install or composer update
How can I find this script and delete it forever?
I have installed clamav and I want to to update the files that it uses to identify viruses:
$ sudo freshclam
ERROR: /var/log/clamav/freshclam.log is locked by another process
ERROR: Problem with internal logger (UpdateLogFile = /var/log/clamav/freshclam.log).
What should I do with this error?
EDIT:
$ sudo lsof /var/log/clamav/freshclam.log
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
freshclam 866 clamav 3wW REG 259,1 100134 10486045 /var/log/clamav/freshclam.log
Before I removed Windows 7 from my computer and replaced it with Ubuntu, I had over 257 threats that never would go away. I don't know if the trojan horse I had also could transfer over to Ubuntu. Can my computer be infected? I'm trying to be very careful when I use my computer, because I don't want to get a new computer.
I've only had Windows 7 and my PC, for only a few years. First, I took it to Best Buy and they said a trojan horse is supposed to be on the computer. The man only "looked" at it and since he put it in factory settings, it hid and stole my PC twice in a row. Then, I took it somewhere to someone I know and they re-built it. But it had tons of issues again.
My anti-virus and my programs and other files were disappearing right before my eyes. My Wi-Fi was turned off, and I couldn’t turn it back on. It even shut down by itself. And it never did that before.
Will my infections from Windows 7 transfer over to Ubuntu? Just remember I don't have windows 7 any more, I only have Ubuntu.
