Probs wid comp pls help?

i recently downloaded a file and everytime im on the internet,a pop up tells me my computer is infected with trojan and i shud download this anti virus.this pops up about every 2 mins.

ive been having probs with my computer for a while tho cos it often displays a blue background with white writing and then restarts.

ive tried running norton, which doesnt work and ive cant see the file anywhere in my add and remove programmes.im getting a new computer soon,but i am mainly worried about sum1 seeing my passwords in the meantime

im trying everything and nothing is working. lol im getting a lot of porn sites hidden under other things in google

Your computer is now being infected by viruses,Trojan... Your computer firewall have turned on and realised the danger of the infections so it request you to download some of Anti-virus program to clean up those infections (by alert for every 2 mins)

The only way you can do now is install or download an Antivirus program as soon as possible because when the Trojan or any harmful thing in your PC are cleaned, the pop-up will be automatically turned off. All problem will be solved. (The restarting problem and your Norton files are also because of the trojan, virus so don't care about that just quickly install a new Anti-virus program and be careful with anything you want to download)
Here are some security software i think might be helpful
ZoneAlarm Pro Security Suite: http://www.mediafire.com/?fz5t29zz6zj
open the file download with winrar and start to install

Kapersky: http://www.kaspersky.com/
Bit Defender:http://futurenow.bitdefender.com/bitdefe...
It can't see your password if it don't have enough time. First iit'll multiply itself and take a lot of your free disk space first(first 2 weeks), second it'll mess your Windows (to reduce your defender) and then begin to steal. Hurry to get the softwares!!
The trojan can do the blue background is "smitfraud" ( it can easily be cleaned but after that you should reinstall Windows because the background is difficult to change again or waste a lot of time)
Good luck to you

go to iobit.com and download advanced windowscare v2 personnel for nothing. once downloaded it's 3 click of the mouse to get rid of problems.

Also there is spybot which is also free

if u are gettin a new comp
master reset ur old comp which should delete everything on der and leave u with factory defaults

Try any of the two links to remove.

These are both free and both excellent.
