my imac is infected with a bug.Help

What bug? Infected how?

If the problem could be adware or malware, a product you may have inadvertently downloaded

to do something and then found the computer acted up, there are ways to remove those things.

However it helps to know what computer model build year and OS X the machine is running.

Then what the problem is, with detail to describe what it is doing wrong, or not doing right...

If you have odd issues in Safari browser, there are methods and descriptions here that may help:

•Remove unwanted adware that displays pop-up ads and graphics on your Mac - Apple Support

•Adware Removal Guide:

•Tech Guides: (malware, adware, & performance guides)

Until communication is established, we can only wait to see what you can tell us about the problem.

For the most part, Macs just do not get infected.

In any event, a reply could help...

Good luck & happy computing! 🙂
