Hello! Last night I was downloading something off a file hosting site and I accidently clicked on an ad that popped up and then froze my computer, later I got an error message from my windows security centre (I used windows xp professional edition) said that "my computer is infected with a spyware "and that I have to click on that balloon so as to get rid of it! so it downloaded some program called "Bravesentry" that kept scanning my computer and got a result of like 65 infected objects in my registry! whenever I tried to get rid of it it kept opening again and again. Then I closed the connection and the computer and when I came back I found that my desktop wallpaper is gone and all I have is the background color only! I tried to open windows task manager so as to see what's going on it was gone! I paniced so I googled "How to fix the task manager" and it got me to this website that directed me to use the "group policy command via "Run" I got to finally understand what's going on , that the spyware disabled my desktop and my task manager so I enabled them again! Everything went back to normal but this came up; 1- The Hightlights under the folder names , ironically that color is the color of the theme's background! 2- I tried to go back to the "group policy thingy" but the damn luck I was in the elecricity went off so when it came back , I opened it , it gave me this error message in the pic above! My questions are; 1- How do I get rid of that highlight? 2- How to restore the group policy? 3- After the attack my connection is kinda slow, do you think it has something to do with it? I mean could the spyware still be there? if so, how do I get rid of it? Knowing that I don't use a spyware porgram and my antivirus is AVG free edition! I'm very sorry for being long but I have no one to ask! Please respond asap. Thank you very much.
