I am not sure if I am infected or what is going on.For the past 10 or so days my computer has been running very slowly. Opening more than one tab (in firefox, my default browser) is just painful to do, it just takes so long. Forget watching videos...skips, freezes, goes back to the start or just pretends there is no video to be played.
I used Ccleaner at first just thinking my cpu was just running slowly, it did nothing to help. I was told I should try using waterfox because it runs faster, so I downloaded that. The first time I tried running it I had 4 or 5 things pop up (comodo defense) saying programs (avg, java i believe, and others) needed full access to my computer, but instead of asking my permission, they sandboxed them. Unsure of what was going on, I uninstalled and deleted the program. I was told that waterfox couldn't have been the cause, so I tried redownloading it. That time when I went to install it it said "file corrupted." A few hours later I did redownload again and install "successfully" at least that's what it said.
So now by this point, 6 hours ago, videos just wouldn't do anything. Kept saying media error. I tried to use Chrome instead but it came up and told gave me a error message
"Cannot connect to the real www.google.com

I scanned with avg and with adaware and it found nothing. I was told to run a combofixer. After running that, I tried to open waterfox. The program was unresponsive and a comodo alert came up trying to run helper.exe, but it said I should not allow it, so I closed waterfox. Then I attempted a system restore. And got a message saying it was not successful and that nothing was changed.
"system restore failed to extract the file (c:\) from the restore point. an unspecified error ocurred during system restore (0x8000ffff):
It told me to pick a different restore date and try again, but the only other options I had were after my problems had started.
OK, and now after doing all of that, my computer seems a bit faster but is still not running videos fantasticly and still keeps popping random things up already sandboxed. And I cannot use waterfox. Does this sound like a virus/malware or something about waterfox? I am no good at this kind of thing and I have stumped my usual go to guy on this. All help will be greatly appreciated. Thank you.
