What's Your Worst Virus Infection Story? | Conficker (aka. Downadup, Downup, Kido) used a Windows vulnerability to aggressively attack millions of computers and build a massive botnet. Over a year later, 1-in-10 computers are still vulnerable to Conficker worm!

Symptoms

  • Account lockout policies being reset automatically.
  • Certain Microsoft Windows services such as Automatic Updates, Background Intelligent Transfer Service (BITS), Windows Defender and Windows Error Reporting disabled.
  • Domain controllers responding slowly to client requests.
  • Congestion on local area networks (ARP flood as consequence of network scan).
  • Web sites related to antivirus software or the Windows Update service becoming inaccessible.[54] User accounts locked out.[55]

Nearly ALL systems at my former place of employment needed to be low level formatted, reimaged, and patched. There was another virus that ate up hard drive space, but I don't recall the name.

One time I got a virus while I was still on my computer. It was really cool to see it popup all this crap, I was actually praising the creator because of how good of a job he did. =)

Were you on a Macintosh? I doubt that, but I will ask.

I got a virus on my computer once (running Windows XP), and one time when I was showing my dad something it started flashing porn and I couldn't get it to turn off. I was in a lot of trouble until we took it to the computer shop and the guy told us it was a virus. Then I got ice cream cause my dad felt bad for yelling at me.

The absolute worst is honestly not Conficker. The worst I know of is called skunk.exe. This nasty infects a computer and immediately overwrites EVERY .exe file on the machine. I am not exaggerating. I helped to diagnose an early case of this, and watched as every major security expert in our community attempted to figure out a way to stop it. It's not possible. If a computer contracts this baddie - it's toast. Period. A friend of mine - the man I consider to be THE foremost expert in malware removal - threw this onto a test machine. I sat on skype with him as he watched it, taking notes for him as he talked out loud about what was happening. The overwrite was complete in under three minutes flat. It was amazing... and terrifying.

The good news is, the virus writer is an idiot. While the virus is devastating and powerful as hell... it works TOO well. Since it overwrites EVERYTHING... it ends up having no way to spread itself to other machines! :)

Somehow I don't think the trojans came from a legit itunes update...

I do not get virus on my own system.

However once I was working on a computer with Windows Xp with NO service packs in 2006-2007. Wow, once I got in the updates it worked fine and no longer had issues, there was also the issue of the type of sites this person went to, no service packs plus said sites, the only way to fix it was to update the backup and reinstall the OS.

I bought medal of honor airborne. and while i was buying it at a game store i left my PC on doing a scan. When i came back it said no infections found. So i put my game in. Powered up the setup. Setup exit after the first step. Then a fake security center came up lol. I got this game from the Game a genuine game store. Weird huh? O.o Although it would have been a random remote hack conveniently done.

My uncle got a stupid trojan, turned out it killed a protocol and the internet didn't work at all. I had to resort to a reformat, but I did get $20 for it. Other than that my computer viruses have been mild at worst.

I had a virus in System Volume, atleast that's what my anti virus program told me. I had to reinstall to get rid of it.

You don't have to reinstall for that. Clean up the machine, set a clean restore point (killing all others) and you're good. System Volume is your system restore. ;-)

Magistr, when I was running Windows 98. That was the first and last time a virus managed to do large amounts of damage on one of my systems, because after this I became incredibly security-conscious (paranoid, even).
