Removing Malware on Older MacBook

[aboynamedsue]

I have an older MacBook that I think is infected with malware.  I am using Mac OS X 10.5.8.  I am unable to install Malwarebytes on it and need  help. The symptoms show up when I am using Safari and include web pages displaying  blank screens or not displaying correctly.  I am posting from a different computer because I was unable to on the Mac.I read the Mac malware and adware removal guide at the safe Mac site but what I am seeing doesn't match up with that. Thanks for any help.

None of what you are describing sounds like malware to me, which is probably why the Adware Removal Guide wasn't helpful. Rather I would have to guess that your browser is massively out-of-date and unable to handle modern web site coding. Web technology has changed greatly since you purchased that MacBook, with little incentive to make it backward compatible with older browser software. So the browser you are using (Safari) is both unable to interpret some of the HTML coding accurately as well as underpowered to process it quickly.

You don't say what model MacBook is still running OS X 10.5.8, but even the original 2006 model is capable of running OS X 10.6.8 Snow Leopard, so I would encourage you to upgrade to at least Snow Leopard for improved performance as well as to have some built-in malware protection: Mac OS X 10.6 Snow Leopard.

I'm not aware of any modern Anti-Malware software that will run on OS X 10.5.8 or older.
