I have just set up a new Samsung 4 right out of the box from T Mobile.  The phone is acting really crazy and freezing up. Plus it keeps opening and closing apps without me touching the screen. Should I be concerned and just turn this phone back in to them>?

Whenever I boot my laptop that is running with Windows 7 and Avast Pro, small rectangular windows with red circles and white crosses pop up. They are marked "–user" and I get rid of them but they keep showing up again. I thought it was a virus but scanning my computer reveals nothing serious. Please help

My laptop has recently been affected by the CTB locker virus and all the word, pdf and excel files has their extensions turned to .ximsrci, making them impossible to open. If I try opening them with word, the data is all encrypted. Can you help me retrieve my files since they had very important information?

I used to use Eset NOD 32 antivirus on windows 7 but ever since I upgraded to windows 8.1 pro, it is giving me problems. I installed it but it did not fully install, I have tried removing it but it cannot be uninstalled. This leaves my computer with no protection. I have tried software like Revo uninstaller but none of them has helped. How can I uninstall it without damaging the other programs?

I think I picked up a nasty  virus called Ads by Positive Finds. It is stealing my data. Plus freezing up my whole system. I have tried every program but nothing is getting rid of it. Do I need to wipe my system clean or is there a way to get rid of this?

I bought Norton Anti-Virus and installed.  I have tried restarting my computer, uninstalling and reinstalling the software, and also tried running to see if a virus is preventing me from installing with no luck.  Did I follow all the applicable steps?  Should I try purchasing another product and installing?  I hate to buy another product but I'm out of ideas for Norton.  Thank you.

Is it possible to have a virus on a cell phone that is causing crashing of my phone?  I am hoping to not have to buy a new phone or buy anti-virus software for my Android, but I keep having a repeat issue.  I am using the phone, and it just shuts down.  The battery is fully charged, and I can't find other concerns.  Is it possible it is a virus or more likely an issue with the phone itself?  Thank you.

I wasn't familiar with some of the Antivirus Software that existed in the market. Although, I am curious about the Antivirus Softwares that providing the Free Antivirus and Keygen that you need to pay for monthly or yearly basis. Which has the better feature: Free Antivirus or Paid Keygens? If I'm using the Free Antivirus, will it provide almost the good security features as the Paid Keygens do? 

Are we going to face the problem of virus in Windows 10? Do we still need to install Anti-virus in Windows 10 and worry about our system? Is Microsoft doing something to remove the problem of Virus from the upcoming version of its OS? Are there anything which the developers are involved in to meet the demand(No Virus) of thousands of users from around the globe?

We have a lot of children in different stages of using the internet so we installed the Mcafee that came with our internet service. There is suppose to be weekly reports emailed to us on all activity that the kids do online.  So far we only get one every few weeks and it is random. Not every child is being reported like it said it would.   Is there a setting that I am overlooking? Any suggestions for a free or low cost alternative?
