.zip vs .sit vs what?

There usually isn’t an argument on this. Stuffit (or .sit) is for Macs and .zips are for PCs, and that is how I have always handled it, depending on who I was sending files to. But recently I found that I couldn ‘t send .zip files to a company. Their virus software decided that .zip files always contain viruses, and so was stripping them out. (The example shown is not the same company, but it is interesting that it says the same sort of thing.) In fact, my isp is also stripping out .zip files sent to me, as it sent the following message:

An attachment named maker.zip was removed from this document as it
constituted a security hazard. If you require this document, please contact
the sender and arrange an alternate means of receiving it.

We finally solved the problem by changing the spelling of the suffix, but I’m told since then that the company policy is now they will send all compressed files as .sit files.

This is just another instance of hackers not bothering with the Mac, because it is such a small market. In fact, I’m getting more and more times that clients are telling me to put .zip files up on ftp sites, rather than having to fight with their isp security to get the file. sigh

What is interesting is when I google for zips and viruses, I come up with quite a few hits. But when I google for viruses and sits, I don’t come up with quite as many, although it appears that some security programs are painting .sit files with the same brush, according to an article from UC Santa Cruz. I wonder how people are going to transferring files there.

In fact, I wonder if we will have to go back to sending things through the mail again?
