Does Antivirus Software keep PCs safe?

Episode 1389

Alan from Los Angeles, CA
Antivirus symbol

Alan wants to know if an antivirus utility is any good anymore for malware. How about on a mobile device? Leo says that all too often, an antivirus leaves people more vulnerable because most malware is a zero day exploit. Antivirus can't stop users from themselves, either. All antivirus utilities have to hook themselves into the OS at a very low level and the virus can actually use that as a door to more exploits. So at the end of the day, an antivirus really is only of limited benefit.

How can I clean up my contacts on my Mac?

Episode 1387

Doug from Murrieta, CA
BusyContacts

Doug wants to delete, merge, and generally clean up his contacts list on his Mac. Leo says there are a number of contact managers out there that will do this, but Leo's favorite on Mac and iOS is BusyContacts from BusyMac. It's not free, but there is a free trial, and it's a very nice contact manager. This will also pull in contacts from social media as well to keep things up to date.

How can I recover missing data?

Episode 1386

Annie from Las Vegas, NV
Piriform Recuva

Annie had a video file folder on her computer that disappeared. The folder, files — everything. Leo suspects that a disk error occurred and when it was cleaned up, it was removed. More likely, the folder entry in the file allocation table was removed. Chances are, the data is still on her hard drive, they just can't be seen by the OS. It's like losing a card in a library card catalog.

Can I upgrade 32 bit Windows 10 to 64 bit?

Episode 1383

Greg from Aspen Park, CO
Microsoft Windows 10

Greg has an employee who downloaded the 32 bit version of Windows 10 and installed it by mistake, rather than the 64 bit version. Can he reinstall it? Leo says that he'll probably have to wipe the drive and install from scratch. So he should make sure to backup the data first and then format the drive. He can't just upgrade on top of it, unfortunately.
