Does I need to format all drive?my anti virus is not up to date and when I connect the dongle,my anti virus block that.tell me what to do?

First install a Trojan remover and disconnect your PC from Internet then scan then whole computer. After completing the scan you will find some option in tools menu like reset windows policies, reset internet explorer policies..etc and run those tools, If these actions cannot be performed in Normal Mode and go to safe mode run these actions and then boot to normal mode.

Then try to update the virus definitions of the antivirus if not updated getting an error just uninstall the antivirus and install the avast free antivirus, update it and scan whole computer if threats detected delete or clean them, however it is the free edition which has limited features and you can grab the full version from the official website.

If the trojan remover not worked or antivirus not performed well then you need to format the whole system because if you format the primary drive that might be not useful because the virus still present in other drives of your PC. Better backup the important data to other external drive and then format your system.

Try to research on Internet by entering the virus name removal tool and some security websites provide removal tools for win32 version of threats.

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

My computer has a virus because I called Microsoft and asked and they said it did, but I don't have the 200 dollars to pay to get it off. I have no security and the virus disabled any type of blocking I have on my computer. It even said the main windows blocking thing was off, but the virus is making it unable to turn the blocking on! I have no way to download anything, the virus blocks anything from being downloaded, saying it contains a virus... what do I do?!?! I'm looking for a last resort here, that's free... do I shut off my computer until I get help? What happens if the virus or hacker goes into my bank account or gets the information... DESPERATE HELP NEEDED HERE

If you don't have any important data, my suggestion is to format your system and fresh install of operating system and after install a good internet security where it scans all the drivers and cleans your computer.

If yo have any important data, go to safe mode and backup your data to other drive or pen drive and after that install a trojan remover and scan the whole computer and reset the windows policies, internet explorer policies, disconnect your system from internet.

First thing remember if you are connected to internet you must have good antivirus, better it protects your PC from attacks...etc.

Install a Avast free edition, it blocks viruses, trojans..etc and also they provide 1 year free license.

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

In my point of view the system restore can not help any desktop or laptop, just it restores the system files or system to the previous state.

If your system is infected with virus, trojans...etc then you are trying to restore the system to previous state, may the virus does not allow the system to restore to a previous state. Most the infected systems which I observed system restore does not work, it gives a message "system restoration fails" and after that it it restarts.

May the system restores works in safe mode, once try in safe mode. Better install any free antivirus and update it and scan whole computer. I prefer to install Avast free edition antivirus, they provide one year free license and install it update and scan the whole system.

I assure this process will work, your system gets cleaned. If you are connected to internet, install a firewall, maximum it blocks threats.

Now a days, so many antivirus programes are availble and but in these the companies offering only trial version of their softwares, as avast also offering, but in a different, as the many of programmes offering the programmes in 15 day, 30 day, 45 day, 60 day's trial, but avast is providing the Basic Protection without any cost.

So get rushed to the Avast and get your basic protection too.
