Today (sunday) I went to work to get a job done that was running late. I wanted to open a Flash projector on a samba share and my Vexira antivirus software complained that the file was containing a Win32.Tenga.A virus. I was so stupid and arrogant to think that the file couldn't contain a virus, because I had used it before without a problem, because it was on a linux server and that the executable was coincidentally containing the virus's signature and that the guys from Vexira hadn't noticed. So I restored the projector from quarantine, turned off my virus scanner and launched the projector. How stupid can you be.

A minute later I had 2062 infected executables on my system, my windows would only start up in safe mode and my network connections are gone. That will set me back another day or two, trying to find out how the virus got on our server, scanning all computers in the office and restoring mine.

So always trust your virus scanner.
