This is certainly worth investigating. Before adding files to the archive, we scan the files with an anti-virus program with the latest virus definitions. We rarely find any infected files. If a file was infected, the anti-virus should have detected it.
We try hard to make sure that the every file added to the OldVersion.com archive is authentic. If anything slips by us, we appreciate if someone brings this to our attention.
I am not a security expert, so I cannot tell you why this is happening. However, I uploaded a different version of mIRC 6.01. The new one was downloaded from one of the official mIRC web sites. Feel free to try the new file. Hopefully the problem will be gone.
