This still isn’t a virus

Mac Format - - MAC AOA -

In is­sue 286 you had a let­ter from Anne Gar­vey about MacKeeper. I down­loaded Li­breOf­fice onto my new iMac, and MacKeeper some­how man­aged to down­load it­self with it. Next I time opened Sa­fari, a new search win­dow opened up in­stead of my home­page, so I re­ferred to your an­swer. I deleted MacKeeper but couldn’t find the helper folder you men­tioned. How­ever, in Sa­fari’s Se­cu­rity pref­er­ences I found a plug-in called ‘trovi’ had been added. I blocked the plugin and restarted Sa­fari. It then opened to my home­page, as it should. I have now re­moved the plugin. Peter Sims MacKeeper is a util­ity nor­mally classed as a Po­ten­tially Un­wanted Pro­gram (PUP), but for ‘po­ten­tially’ you can read ‘def­i­nitely’. PUPs are like pay­day loans: not ac­tu­ally illegal, but the world would be a bet­ter place with­out them. You won’t see the helper folder, un­less you’ve run MacKeeper, which isn’t likely since it doesn’t do any­thing you want.

Trovi Search is another, un­re­lated PUP that hi­jacks your home­page. An­noy­ing par­a­sites are some­times bun­dled with free soft­ware to make money for the devel­oper. More of­ten you’ll get them by ac­ci­den­tally click­ing on a fake down­load but­ton. The but­ton at li­breof­ is safe, and so is the Mac App Store, but sites of­fer­ing lots of use­ful util­i­ties are no­to­ri­ous for this.

Be­ware of big down­load but­tons on web­sites, which are of­ten there – along­side gen­uine but­tons – to trick you into in­stalling ad­ware.
