Try this.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up

Getting rid of anti virus

I once put Norton anti-virus on my 20" iMac. That was like 4 yrs ago. It's out of date and I want to remove it but I can't get rid of the virus scan no matter what I do. I have trashed every known instance of Norton in Applications etc, searched with spotlight, looked thru libraries, utilities etc and I still can't find where that darn virus scan is? Any ideas?

You can download the uninstaller directly from Symantec’s site.
If that does not work:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, Easy Find, instead. Download Easy Find at VersionTracker or MacUpdate.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
AppZapper
Automaton
Hazel
CleanApp
Yank
SuperPop
Uninstaller
Spring Cleaning
Look for them at VersionTracker or MacUpdate.

Ok then one last dumb layman's question...how do I rid myself securely of mackeeper/cleanmymac/norton? Does my Mac have an uninstaller or do I just dump them securely into the trash from Applications in my finder?
How you remove an app depends on the app. There's no built-in uninstaller in Mac OS X. Apps that were purchased through the App Store can just be dragged to the trash. Apps that required an installer should also require an uninstaller, and that uninstaller should be provided by the developer. Apps that are installed just by dragging to the Applications folder are a bit of a gray area... they should be removable just by dragging them to the trash, but sometimes such apps will install things that run in the background and that need removing. You'd need to see if the developer has removal instructions or an uninstaller.
There are special cases, of course. MacKeeper, for example, requires an installer, but has no uninstaller. Instead, you just drag the app to the trash, and a component of MacKeeper will notice that and ask if you want to remove it.
To remove Norton, you need to run the original installer, which will offer to remove Norton if it's already installed. If you don't have that installer, you can re-download it or check with Symantec about an uninstaller.
As for CleanMyMac, here's what the developer has to say:
http://macpaw.com/support/cleanmymac/knowledgebase/how-to-uninstall-cleanmymac-2
As a general rule, when dealing with apps from outside the App Store, you should always find out how an app is properly removed before installing it, as some apps from irresponsible developers may need - but not have - uninstallers. If an app doesn't have an easy removal process, you should think very carefully before installing.

Recently I received a RCMP UKASH virus on my iPad mini. How do I get rid of the virus?

Recently I received a RCMP UKASH virus on my iPad mini. How do I get rid of the virus? Also will it affect anyone else's mobile devices?

Your iPad cannot get a virus, so there is nothing to clear or clean up. Read this discussion and while it has nothing to do with the iPad, see Thomas Reed's response at the end of the thread.

A virus called "flash player pro" has entered my iPad. I cannot access Yahoo, iTunes. Or Facebook. How do I get rid of the virus?

A virus called "flash player pro" has entered my iPad. I cannot access Facebook, Yahoo, or iTunes. How do I get rid of this virus?

Your iPad does not have a virus unless it is jailbroken. Close all apps nd reset your iPad. Clear Safari as well.
Go to Settings>Safari>Clear Cookies and Data.
Closing apps in iOS 7 works like this. Drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Need help getting rid of Trovi virus on Safari and Chrome. Cannot use the instructions Apple sent because the copy command under the edit tab does not work.

I use OS X 10.9.5. I have a trovi virus on Safari and Chrome. Yesterday I thought I had gotten rid of Trovi, but it's back on both my search engines. The directions Apple sent yesterday do not work; the copy function under the edit tab is grayed out and non-responsive. Can anyone help me to get rid of this virus? Thanks.

Are you referring to these instructions?
Remove unwanted adware that displays pop-up ads and graphics on your Mac - Apple Support
If so, be sure to read the instructions carefully, and note that you will need to repeat the numbered steps in the Conduit/Trovi/SearchProtect removal instructions for each line shown, not all together.
If those instructions aren't working for you, for whatever reason, try my Adware Removal Guide. It provides similar instructions, worded differently, as well as an app (AdwareMedic) that can help you do the removal automatically.

Can't install Lion get the message "recovery system can't be created" -see picture of my screen

So I have been trying to install Lion for 2 days. The screen below is what I keep getting. Here's what I have done so far...
1.) Delete files (I have now have about 50GB free)
2.) Complete all updates (running 10.6.8)
2.) Disk Utility repair with Snow Leopard CD
3.) Remove Lion and re-download
4.) Went to the www.apple.com/support/norecovery page, but the solutions didn't seem to help or really apply to my problem
No matter what I do, the following occurs:
1.) Starts installing (says it has 33 minutes to go)
2.) Gets to about 29 minutes and I get the screen below!
I even went to the Apple store today and tried some of this with a One to One assistant, he couldn't resolve it either and hadn't seen this message before with anyone else. When he asked a "Genius" he told me to delete more files. But that didn't help either!!
HELP!!!!

Hi!
I Have a macbook pro 13' core 2 duo 2.53Ghz and am getting the exact same reaction!
it's been a few hours since i've been trying to install lion. Download took about 2hrs and everything fine until, each time i've tried, announcing exactly "33 minutes" and popping up that screen a few minutes after a stuck "29 minutes"
Anyone has ideas?
I've seen a lot of threads and thought it might be because of that Paralell windows 7 i never use. But I even tried deleting it all and the problem persists. I'll be at the apple store tomorow and try to figure something out.
this is just not fair...
my screen:
Yet... I'm still really excited about Lion! I'm pretty sure this nightmare will be worthy after all! Thanks for helping out!

HELP PLEASE! Green marks near words on web browsers can't get rid of any ideas

I have as soon as i click on a link on the web pages - green marks appear near words and they open up a new tab which shows advertised pages - how do i get rid of them. I have run spy ware but does not remove or change anything ,,, Thanks

You may have installed one or more of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the "VSearch" malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.
Back up all data before making any changes.
One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Still in System Preferences, open the App Store or Software Update pane and check the box marked
Install system data files and security updates (OS X 10.10 or later)
or
Download updates automatically (OS X 10.9 or earlier)
if it's not already checked.
