First of all, McAffee is a (limited) partner with Adobe in that they participate in a "per click" imbursement program for Flash Player downloads, so for them to tell you that Adobe is a source of malware is a conflict of interest to say the least, and an outright falsehood to be blunt. Adobe is not, and never has been, in the business of distributing harmful software. If they were, it's not possible that McAffee would add their own software to downloads from here.
That said, there are thousands (literally) of websites that offer (illegally) Adobe logo'd "fake" updates, which DO contain adware, spyware and outright viruses. It's possible that McAffee support believed they were referring to a legtitmate Adobe Flash Player when what they were seeing was a "fake".
There are direct sources for Flash Player downloads:
I use them myself on six Windows machines I have, because I don't "auto update" anything, including Windows. Bookmark those, because when the versions change, the links do not. Use them to update your current vesrions and McAffee shouldn't "flag" anything with either of them. If you DO see a warning, DISABLE McAffee until you've successfully downloaded and installed the new Flash Player Plugin(s), and THEN re-enable it.
Thanks. I have been a user of Adobe for many years now and this was the first issue I have ever had.I could of swore I went to adobe,com but maybe it was a dummie site. Will try again from links provided and see what happens.
Just now tried link and still get a Big flashing banner from McAffe saying could harm computer. will disable and see what happens
