Well, at least they work most of the month? Sounds like a script might be a good idea to reset all the exclusions. McAfee refuses to honor my exclusions and constantly tosses the Steam games I mentioned in quarantine, while I'm playing them.

Why are people trusting the games to be secure?
We have had a number of games with built in spyware so who knows what else they are doing.

Play any Unity games lately?

Spyware is a bit different than viruses.

You're only assuming people are trusting games to be secure, but with Steam there's a reasonable expectation that they will be. I expect them to be moderately secure considering the files being downloaded by Steam, proprietary software connecting to proprietary servers to download files, supposedly in a secure manner, where the database is also maintained and checked for integrity from time to time or handling reported issues quickly. I also double check any positives online to see if other users have reported the same issue when one comes up. So no, I really don't "trust" them to be secure because I've been out there long enough to know better. The topic is specific AVs that find false positives in games whereas another AV doesn't.

On a side note, there's been retail copies of software on CDs that shipped with viruses. I found a pretty nasty one on a CD of an old game when my AV started up with the disc in the drive.

Ah, wrap your potato in tin and throw the fish away, they've got mercury!

What you call spyware, do you mean the typical data metrics practically all software has in some form or another, or do you mean, actual spyware?
