Follow these steps to a completely secure computer. Download and install all of these free programs. It鈥檚 allright to have more than one anti-spyware, but not anti-virus so make sure you have removed and uninstalled every bit of your old antivirus and firewall as these can cause unwanted conflicts.

Now restart your computer twice to ensure all or most of the programs have been properly installed. Make sure to update all these programs everyday. Now that you have updated all your programs go turn off your computer. Now hold on F8 right after you turn on your computer and that will bring you to the menu to go to safe mode. Hit safe mode and log in. Now launch up all the AVG programs and wait about 2 hours as it鈥檚 the first scan. If the programs have found anything simply delete the infections. After that, run spybot, adaware, and a-squared free edition, if they detect anything, simply delete those infections too. Then, after those run a full scan on windows defender it shouldn鈥檛 find anything by now and if it hasn鈥檛 then your computer has been cleaned of bad infections. Now its time to clean up. Run each of the clean up programs one by one. Now you have a safe, healthy, clean computer. And try to download these top internet browser.

Reply:Write the name of it down, and look on google to make sure it is a virus.


A lot of things repoted as viruses are not a virus.


If you are sure you have a threatening virus, then write it in google window saying "how to remove".
Reply:Post about the behavior of the virus and use av like bit defender the best out there....
Reply:Use a good anti-virus!





Kaspersky is the best!
Reply:Scan in safe mode.
Reply:check what services are running on your pc automatically and also programs that run on startup. Pretty much keep your eyes open on non-microsoft services you dont recognize, and on files with bizarre names that run on startup. It mentions the program name there so if u dont know it, disable it and see what happens.








Start %26gt; Run %26gt; msconfig


(Check the services tab and startup tab)





Usually its something running from a temp folder. Or sum shareware downloaded that includes a virus.





Good tools
