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.

My computer has been taken over by viruses. My anti virus does not remove viruses and any new anti virus I download becomes infected. Need help.

May be your computer is at high risk, because when you install any antivirus or any other programme it is infected. This means that virus and its infections are very high in your computer. If you insert any USB drive or any external drive, virus might damage your data. Before doing all these if you have any important data take a backup of them.

After taking backup of data, format your OS drive or C drive, After doing the same you need to check with other drives. But I assure you that other drivers like D, E ...etc are also infected. After formatting and loading the OS you need to install the Internet Security, why I am saying Internet Security means it has all the features like spyware, Malware  root kits  virus protection...etc. If you want you can try trial version of Norton Internet Security for 30 days.

After formatting and installing OS dont install any drivers or any other software's  Just install the Internet Security programme. Update the virus definitions  and scan the whole computer. I assure you it detects and removes threats, if that feels good buy full version of the software.

But every time install a security software's  don't overcome that my pc never gets virus or I am sure my USB drive does not infected with virus. Any way so many antivirus programmes are available on Internet, Free version of antivirus is Avast that was good enough to protect your PC. 

Its a 16gb usb flash drive and I have used it in the past, but I deleted data and it still says that it has 15gb used and wont take anything more than 1gb. CAN SOMEONE PLEASE EXPLAIN WHATS HAPPENING?

Sol:- As the pendrive is 16gb, after deleting all the data it is still showing the 15 gb in use, which means a possibly virus file is in the USB drive.

 

You need to unhide the files. go to tools-> folder options->show all files.

Now the hidden files are shown and you can select them all and delete them.

If problem persists you need to format your usb drive and you format your pendrive using some format tools which can available on internet
