My brother downloaded a game demo and it made my computer slow and now im getting pop ups to buy antivirus and anti spyware protection. The pop ups are gone now after i used AVG but now on the bottom right corner of my screen it says that my computer is at risk and that i should download a certified anti virus and spyware protector. How do i get rid of that because i know that eitehr spyware or a virus put that there. I used spy-bot search and destroy but it didnt find anything and i used AVG which cured the pop ups but im still getting the same sign. So what should i do now and should i go into safemode? please help and fast
this can be caused by a rogue software..a scareware that uses trojans or other harmful programs to get installed on ur pc and tries to panic you with telling u that your system is infected to purphase a certain product..

If you’re comfortable with Safe Mode (looks like you are), that’s good and here’s a quick advice:
1. Download a-squared command-line scanner:
http://hubpages.com/hub/free-malware-removal
Unzip the anti-malware archive to C:\acmd
2. Restart and go to Safe Mode (hold F8 key when you hear the short beep).
3. Logon and proceed according to the instructions in the hubpage.
I believe you have removed most of the malware, the remaining file or two (displaying that sign) cannot download additional parasites. But even those remnants should go away.
