I ran my anti virus software, Norton, to get rid of a dangerous file I just downloaded. Right now it's stuck on a log for a game I downloaded, but I'm pretty sure it's found the virus thing because it says 105 security risks detected and resolved. So, should I close it or keep it running, because it's been sitting on this screen for a while now and would it be okay, if I just went ahead and hopped on the Internet if I can't close it?

Yes you can close it and it just showing the results of the scan and if you find any important in that and the result will be displayed on the right side of the window. Some viruses or infected files cannot cleaned, whether if you want to delete or move to quarantine you can do that manually.

Some antivirus cannot clean the compressed files because the antivirus has limited features those are may be trial versions or free versions. After scanning they will display the results and showing that which files are infected and types of virus, action taken on them, if you find any compressed file check whether that file is realted to you or not and dont just delete all the compressed files.

I suggest you the full version of antivirus has the deep scanning parameters where it scan the total compressed file and cleans that particular in that file so better have the full version of security softwares. Most of antivirus cleans the trojans aswell if they cant download the trojan remover where it cleans the trojans files and have many better features

I work on computer about an hour or so and every time I switch off my computer, I need to restart it before switching it off. I do not know why it happens? There is no virus in my system as I use Microsoft Essentials and it cleans my computer from any sort of malware or virus.

Might be there is a virus in your system because of the threats that present in your system this is happening. Do one thing just remove Microsoft essentials and install the latest antivirus full edition like Norton internet security they gives you a 30 days trial where you can scan the whole system for threats and it protects your PC for 30 days if you are satisfied with it you can buy a full version.

Say some antivirus like free edition or shareware version doesn't scan in-depth of a system where the threats still present and the system files will be effected so you need to know that free edition has only limited features in order to get rid of these types of threats you need to try these Panda  Symantec ..etc they provide trial version for 30 days and you can observe the change.

Many people don't know just they bought antivirus of dollars but the functioning and features were not known by every consumer just they bought installs it in system that's all. One should know the features and options available in the Security software's.

In my point of view, Norton 360 premier edition is the best one because the Norton 360 premier has backup utility where it backups our data and restores the data to the original destination.

Norton 360 which has limited features where backup and pc tune up is not available where Norton 360 premier edition has.

I have used Norton 360 but it seems to be not fit to my computer where my system is low in configuration and my system will become very slow when I installed it and so I removed it, Installed Avast free edition that was better for me.

Not only 360, any security software that is provided by Symantec was awesome and in that Norton 360 premier edition provides 25 GB of cloud storage that is also a secure. Just don't install the Norton Internet Security which has the better features where one can afford to buy the security software.

Once before buying or installing the antivirus once check the features of the that particular security programmes and so you will come to know whether need to install any new softwares or ...etc

The best free antivirus is that Avast in my point of view that is the free best antivirus till now and I was using this avast free edition since version 5 and the avast is the major antivirus programme and using since 3 years, I personally experienced a good performance of the security programme.

They provide 1 year license as well which is free of cost and provides upgrades and updates for a year. It scan engine, virus database is awesome and user interface is very nice where one can easily understand the programme and use it thoroughly.

Eset also provides a god antivirus programme, but I didn't find that much performance when compared to Avast antivirus and so many antivirus programmes are available on the Internet. AVG is also one of them and  provides free license for lifetime when I was using it a 4 years ago and problem with this is, If a infected file found in compressed file i.e. zip or rar file, this antivirus programme deletes all the data means the complete rar or compressed file will be deleted and so other important files in it will be lost.

That was the time I was searching for a good antivirus and I found Avast. 

Symantec Norton is awesome which I used a Trial version for 30 days. If wanna buy I would by the Norton Internet Security or Norton 360.

Better buy full version of antivirus programmes for a better protection

So whenever I open a web browser (usually Google chrome) and go to any site, my anti virus software always detects 6 trojan virus. I have avast anti virus by the way, its the free one though. I also downloaded some movies and songs through torrent. Maybe that's why. So I scanned my computer and deleted the infected/infectious files. But its still the same, they still detect a virus. So I'm freaking out here. What should I do? Is my computer really infected?

May be your PC is still infected with Virus or Trojans, You need to scan in depth of your system files. Avast free edition has limited features when compared to a Avast Internet Security. One more reason behind this is, in your pc some malware software may be installed once check in the control panel add/remove progrrames. Then check in browsers plugin or extensions there might be some unnecessary plugins installed. If you have found one uninstall it and restart browsers, reset to default settings.

Better install a Norton Internet Security Trial, remove the avast free edition. After Update the norton virus defintions. If any threats found I assure you it will remove the threats. and Run a Full System Scan. Symantec provides the Security software with full features with 30 days trial. After 30 days if you can afford buy a full version of the software.

So many malware sites are there in world wide web, people dont know which they should download or avoid. Installing a Internet Security software will protect your PC from all these types of softwares.
