Viruses - from "Sightings in the wild"

how do you know it's never had a virus
...because there are no viruses that attack OS 8.6
That is why nobody (other than scammers) offers anti-virus programs for OS 8.6, because nobody has ever found a virus to test them with.

Disinfectant is one, there's also Norton Antivirus (formerly known as SAM - Symantec Antivirus for Macintosh), Virex, etc... There are still copies of the virii that used to affect the classic Mac OS out there. Also, a lot of the macro virii that affect Microsoft Office will affect the older Mac versions of Word and Excel.

See here: http://lowendmac.com/2015/classic-mac-os-viruses/

New virii aren't being introduced for Mac OS 9, 8.6, 7.5, etc, but, the old ones are still an issue. You really don't want to infect your machine with a virus like nVIR. Spent a whole weekend around Xmas 1993 eradicating every single floppy that I had for my original Mac Plus of that virus. All thanks to a Super Tetris floppy I'd bought at a computer store. Both my IIfx and my Quadra 650 have Disinfectant 3.7.1 on their hard drives, and the hard drive I had in my old Power Mac G4 also has it on it. My Mac Pro and my MacBook have ClamXAV installed on them...

Hi,

My assumption up until now was that you was running Windows on a very old machine.

As I now know that you are running a Mac, I wouldn't worry too much about malware, but I would update the OS to the latest you can. Primarily for the extra features, ability to use newer browsers, etc.

That's the problem, even with the most up-to-date software that the machine will take, I can barely get Flickr to work - it worked OK until recently. If their software is clever enough to identify my browser (and send me an offensive message about it), why can't they send out a lower-grade version of the video? It isn't just the playback software which is causing problems, the bit rate is higher than a lot of broadband connections can support.

The office computer (G3) stays on OS 8.6 because my business runs on ClarisWorks spreadsheets linked by "Pub & Sub" and there is no modern substitute. I was aware that there was a virus which could be spread by floppy discs, but I don't use them - and, as far as I know, there is no way of infecting a G3 with that virus through the internet.

AppleWorks 6.2 should be able to handle the ClarisWorks spreadsheets without problems. It is, after all, an updated version of CW that happens to run natively under OS X. No need for Classic mode. I'm able to run that on my Mac Pro, running 10.6.8.

On the beige, I'd update to 9.2.2. That way, you have the final version of the Classic Mac OS on there and will be able to run it under the Classic Environment under 10.2.8, if you so desire.

Of course, another problem with older machines is that rich multimedia content and large web pages can overwhelm them. I came into possession not too long ago an old iMac (circa 1999). It fired up OK and worked quite well until I started the browser up and it couldn't render the web page at all well. The developers have to cater for the most popular browser and these are often the latest version. IT's a numbers game at the end of the day for developers, they will test for browsers versions that run into the hundreds of millions of users; but they haven't enough time or interest to cater for all internet users.

I went back from CW 5 to CW4 because version 5 was full of useless 'eye candy; version 6 is even worse. Also there is no "Pub & Sub" in OSX to link the components together, so I couldn't print invoices, address envelopes, number tickets, print self-calculating calendars or do a load of other jobs that OS 8.6 makes easy work of.

A very computer-savvy friend has just shown me a way around the problem: he suggested 'spoofing' the browser to make it look like a low-bandwidth mobile device and trick the website into delivering a more economical version of the page. With "User Agent Switcher" I have set Firefox 16.0.2 to appear as iOS 5_1_1 - iPhone - Chrome and I can now download (not stream) Flickr videos at a sensible resolution.

You can also make it say that it's Firefox 39.0.

That said, I would seriously consider getting a 10.6 install disc. Snow Leopard is an improvement over Leopard. Partly because it got rid of a lot of the unused PPC code (still runs PPC software using the Rosetta module, like 10.4 and 10.5 do under an Intel machine) and partly due to bug fixes. I'm running 10.6.8 on both of my Intel-based Macs (early 2008 Mac Pro 8-core 2.8GHz and late 2007 Macbook C2D 2.0GHz). Works fine. I do, however, have a copy of 10.8.5 Mountain Lion on one of the partitions of my Mac Pro's hard drive. Once I update Photoshop and replace some of the PPC-only software that I still use, I'll switch to that. I'd stick with the CS2 version of Photoshop, except for the fact that it doesn't play nice with the image files that the photolab's Noritsu film processing machine produces. CS3 works fine.

You can use an emulator (miniVMac is one, Basilisk II is another) to run the classic Mac OS on your MacBook. With that, you can run CW 4.0 on both machines. Back when I used my PowerMac G4, I found that CW 4.0 worked fine under 9.2.2, either loaded natively or run under the Classic Environment on OS X. So, there's no reason to stick with 8.6...
