The initial screen said something about cleaning my system. And I didn't bite. However I did go ahead with the upgrade after a full backup. With Catalina up and running, now I find it's wiped my MS Office '07 and say I have to upgrade to Office 365 which I probably won't do.It is not really malware, but it is sure an app you don't need, and it is pretty safe to assume most web sites promoting that app was paid to do so.
What it it you are thinking you would need that app to do for you?
It can damage a system and be hard to remove, sometimes needing to restore frpm prior to its install and "infecting" your system. Junkware and yes, harmful and unnecessary. I use to use Onyx. (Even CCleaner has fallen in popularity).I guess it's my turn as the upgrade is ready to roll. Checking the web before starting I saw a checklist that recommemded "Cleanmymax X" before starting the upgrade.
Is this a legit program or some kind of malwear?
For sure it doesn't work. And it's gone from my system. I can't find my old Office suite in my office. The only reason I looked for it was to see if it had a 64 bit installation option.Yeah.. I think that old Office suite is still 32bit and won't work with Catalina.
I would only buy something like that direct from the MS web site. I'd be worried about other sites being scammers.Did a search on the net and found several "download" Office options that claim to not be subscription Office systems for as low as $40.
