Well, at home, we have three computers, two upstairs and one downstairs. One of the those upstairs has firefox, and works normally (with an ethernet cable) the other two have wireless connetion to our modem. At the second one upstairs, we can't open IE, but we could go on MSN, until yesterday, and we can't :( Also, we can't open any explorers, like My Documents. At the one downstairs, we can open IE, but we can't go on any web pages or MSN. We can open explorers, like My Documents. Upstairs has AVG Free as virusscanner, which found a lot of trojan horses and stuff, and I'm running again. Downstairs has McAfee, which isn't updated (we need a password, and I don't know where it lies >.< ) That scan didn't solve anything. Can you help me? errr...w00t 100th post?
