Half-Life 2: Episode One Message Board  

It just did the same thing to me 4 times. I shut off my MSSE active and it downloaded. It is apparently showing up to the updated MS Security Essentials as a trojan virus called: Trojan:Win32/Tiggre!plock

It is quite common for antivirus programs to detect and warn of Viruses and Worms in Trainers because trainer code is hacking the game code. You almost have to ID the trainer to your antivirus/anti-malware program through it's "Ignore" this file tool so that it will leave it alone. I found this works well for a number of trainers that come up with false virus/worm alerts. I run the download attempt 3 to 4 times then I turn off the live protection for the download and complete is. Then I move on and turn active back on. As long as I remember to turn it back off before I decompress the file I can continue to get the file ID information to tell the program to ignore this file during normal or full scans later on.

It helps to save the trainer files to an external drive once decompressed so you can replace it later if there is any fupah that allows your AV/AMW to remove/quarantine
it later.

That's how I deal with these trainer blocked errors.

Just an updated help suggestion.

Thanks CH Team!
