mIRC window on Startup - 15/04/05 01:38 AM

Hey...I recently had a virus on my computer and it now pops up with an mIRC window on startup. Anyone have any clues what is starting this??

I never have even used mIRC...nor downloaded it EVER. Did someone hack onto my PC somehow?

I have been through my registry and cannot find anything. Any help would be appreciated.

Unfortunately, mIRC is used in certain trojans to connect your computer to IRC and then participate in Denial of Service attacks against people, websites and/or ISPs.

You need to scan you computer with multiple virus scanners, also use an online virus scanner such as Trendmicro. Lots of links can be found in this thread. You might also wish to run spyware programs.

Search your computer for 'mIRC' and delete the mIRC.exe file. (Use Start > Search).

Thanks for the info. I had searched for mIRC on my computer and found nothing. I have also ran my computer through serveral virus scanners...I am using a few more that were in the link you provided as I am typing this.

I figured it was a Trojan virus, but I was curious if anyone would know which one would cause it on bootup of Windows.

If there are any other ideas on what would cause this, I would appreciate them as well.

Check that it's not in the Add/Remove Programs section, see if you can uninstall it from there.

You might want to search for 'mirc' or 'internet relay chat' with Symantec's search tool, they have a pretty extensive database.

If you didn't install mIRC, and it's starting when Windows starts, I'm 99% sure that it'll be a trojan/virus and nothing else.
