True or false: Norton protection slows down my computer. See screenshot provided. The process tab has been selected for use. These are what I am seeing in my task manager on my Dell gaming rig at present. Nothing there isn't a legitimate process. They CAN indicate a source of malware and other issues. Open yours and watch for processes using CPU and other resources in an inappropriate manner.

Make a note of what those process names are and which resource is being abused. Lets us know what those are if anything is a concern on your end. How dose this work? I did the scan and was put in quarantine, is this what you mean, or should I do more? I will be purchasing a new MS Office or and install it soon, where is a legitimate site I can find this for a good price? I don't want to interfere with SoulAsylum's troubleshooting, but if you use a free utility from Microsoft Sysinternals called Process Explorer it can give you additional information that isn't available with the built-in Windows Task Manager.

For example, when Process Explorer launches it can be configured to upload every process running on your computer to VirusTotal.

Any suspicious or malicious process running on your system should have a poor score e. If you want to add additional columns to the Process Explorer interface e. Click through all the tabs e. Be sure you also check the applications that start automatically when you log in to your computer at Settings Apps Startup. Each application is rated high, medium or low according to the impact it has on system resources.

If you aren't sure what Startup programs are safe to disable post a screenshot for SoulAsylum and they might be able to provide a few suggestions. Once you've finished cleaning up all the unnecessary programs running on your computer I'd also recommend you post in a reputable free malware removal forum and have your computer checked by a trained malware removal specialist see my post in Greg Michalik's Possible Scam?

Just note that most of these malware removal sites require that you uninstall all pirated software from your computer before they will diagnose your computer. Also note that you should only post in one of these sites and follow their instructions until the malware removal specialist assigned to your case has confirmed that your system is free of malware. Thank you AS and Imacri. Rab60 By now this name should be corrected to Rab PS: I just want to mention that I did not willingly -installing pirated or "cracked" software-, I am not sure how it got there, a friend did this for me years ago.

I found few free office, open office and libre office. I am not sure if they are safe and the download site is safe! I live in Canada and found this product on sale at Amazon. I haven't tried OpenOffice or LibeOffice so I can't speak from personal experience, but I investigated a few free Office suites and thought LibreOffice was the better choice for me. There's a good YouTube video at LibreOffice vs. It has very good support in "manual" form if you click on HELP on the toolbar at the top -- or use F1.

I've used the online version rather than install it and be nagged to update it probably. I'm not an expert on it and I just use it for the very occasional letter or more frequently I use its Spreadsheet to keep track of our monthly income and expenditure. Thank you Imacri and huwyngr for the information. On the otherhand I did proceed with checking my startup applications on the Task Manager, and I was surprised: NO one startup program found all are disabled anyway there are few around 10!!

I will proceed in doing more checking on the WE. Thank you very much for all notes and hints. Do you mean that everything is disabled at Settings Apps Startup, including your Windows Security notification icon? If you want to post a screenshot of the Startup tab of your Task Manager i. For example, I can see Mozilla Maintenance Service listed under "Necessary" so I'm guessing you have a Firefox browser installed, but there's nothing in those screenshots to tell us if services and executables for important programs like your Norton antivirus are launching correctly at boot-up.

Many Win 8. I'm not qualified to interpret these FRST diagnostic logs and these logs shouldn't be posted publicly in this Norton forum , but you might find some useful information there, including a list of all your installed programs, recent Event Log and System errors, etc. A trained malware removal specialist should be able to recognize any process, registry entry or startup task associated with malware in those diagnostic logs and, if necessary, provide a script that will automatically clean your machine.

Any logs posted in that Malwarebytes board can only be viewed by authorized users like the trained malware removal specialist assigned to your case. This might be completely unrelated to your problem, but I just noticed that there are a few users posting in the Norton for Windows board about the Norton executable NortonSecurity.

You might want to monitor the following threads just in case there's a bug in the latest version of Norton. For example, here's what the first few entries in my Processes tab typically looks like sorted by CPU Thank you for this very important hint , for me I used to do this, assuming when I start later it will do the changes anyway!

Rab During the discussion I had difficult time postin screen shots or images, is there any tutorial for this topic , so I can easily do it in the future? Going forward, here are four basic tips that might help if you ever suspect that your Norton antivirus is affecting computer performance. If you have ever had another antivirus installed on your computer like Avast, Bitdefender, Kaspersky, McAfee, etc. This will ensure that any stray files or registry entries left behind by the uninstaller are cleaned off your system and can't interfere with Norton.

Most Norton users in this forum who purchase a subscription for Malwarebytes Premium the advanced product that includes real-time protection report that Malwarebytes Premium can run in real-time protection mode along with Norton without causing problems, but some Malwarebytes Premium users prefer to create mutual scan exclusions in both products to avoid possible conflicts.

This advanced "Remove Only" mode does a better job of removing your Norton files and registry entries and gives you a cleaner reinstall than running the NRnR tool in "normal" mode. On rare occasions the advanced "Remove Only" mode still isn't sufficient and you must manually scrub the last traces of Norton off your system before reinstalling. If you see a significant drop in connection speeds with Norton Secure VPN enabled and a clean reinstall of Norton doesn't help see tip 3 then you will have to choose between security versus speed.

Thank you very much for the additional information. As mentioned before I will slowly will do all I can from your recomended cleaning tasks. For example, I use Macrium Reflect Free to create full disk images for emergency recovery, and I've added the Macrium rescue environment to my Windows boot menu.

That means that I see a prompt every time I boot up my computer that asks me to choose if I want to boot into Windows normally the default after a 10 second countdown if I'm away from my computer or if I want to interrupt my boot-up and perform an emergency recovery. Not every installed program is listed for example, the load time for my Malwarebytes Premium anti-malware isn't on that list of startup programs but the "CPU at Startup" column does show that my Waves MaxxAudio application and the Epson software that manages the wireless connection to my Epson printer have a relatively high impact on my startup time.

For a deeper dive of your startup processes, Microsoft Systinternal's Autoruns utility shows nearly everything that loads automatically on your computer, including programs, services, automated tasks, etc.

If you click on the Options menu of this tool you can hide Windows and Microsoft entries to reduce the clutter in the interface. Don't delete or alter anything unless you really do know what you are doing or you may crash your computer. Before you change anything make a backup image of your system onto an external storage drive so that you can recover to where you were when the system won't start up anymore.

For a backup device unless you have one already I'd suggest getting an external hard drive that plugs into a USB socket on the PC. Just checking Amazon to get an idea:. Some hard drives on Amazon just now Don't forget you may need a USB cable if you do not have a spare already although some may come with one.

Macrium Reflect Free Don't get the trial of the "full version" -- the basic free version does all that most of us need!

It's not hard to use and can save your sanity when not if things go wrong! I find it very useful that having saved an image of my hard drive I can in fact dig down into that image and find a file or folder and look at it or recover it on its own.

You may be using the cloud, as others call it, but you will find it very slow to save or to recover the backup you have made that way. Before you change anything make a backup image of your system onto an external storage drive so that you can recover to where you were when the system won't start up anymore More good advice from huwyngr.

As you work your way through the some of the suggestions posted in this thread you might want to post a screenshot of the Startup tab of your Task Manager so we know what Startup programs are actually disabled. Post back if you need more help posting images in the forum. Following your advice, I did download this application and would love to use it asap , but I do have some questions regarding the HOW to Do! Hi lmacri,. This is what I found in the Task manager , Not realy many and all disabled!

I think I would start a new thread with Macrium Reflect in the title -- that way some others may be helpful. Before you do that do install it from your download -- it won't do more than look at your system and draw you a picture of how your drive s look. Then look on the top toolbar, at the right, click on Help which will drop a list of items and the first Help there will take you to the Macrium website where they have a very complete and easy to follow "book" of help topics.

So look at a few of those. Apart from that and telling it to go ahead there's not much else you need to know IF you have an external USB hard drive to save to. I let it use its defaults although I make sure I understand where it says it is saving to I make a folder on that drive and name it eg: Macrium Images Many people ask this question online.
