I have a Dell PC with XP - Evidently no antivirus is on PC just firewall. Last night a pop up called "Security System" came on screen and showed like 35 virus's/trojan/worms and I clicked remove them and then they wanted payment; so I clicked it off - knew it wasn't Windows. Then I noticed a short cut was placed on my desktop with this Security System so I moved that to recycle bin and went to Control Panel/Remove-Add Programs and deleted the program from there. Then I shut the PC down. Today the shortcut is back on the desktop but I did not find it in the Remove-Add Programs. I then went to McAfee to get their 3 month free download of antivirus and after registering they sent an email to Yahoo to confirm. When I went to Yahoo and clicked on the email and before I could click on the confirmation Yahoo and the Internet went down - 3 times I was taken back to the desktop and kicked off Internet. I also tried to search for AVG which is suppose to be free antivirus and when I hit search the PC did the same thing again. I tried these in Explorer and Netscape. I don't usually download anything on the Internet and the last thing I downloaded was a Tax Cut disk from WalMart. I guess luckily I have not e-filed my return yet since it may not be safe to do so - but need to do them soon! I have to leave house at 1:30 Central time but will be back on at 4PM. By the way another thing is my Yahoo email had a message in it that said the account was going to be terminated unless I provided my login and password to them - which I opened and read the email but forwarded it to an actual Yahoo rep to ask if it was Spam, etc. I didn't think it was actually from Yahoo. Any help would be greatly appreciated! Thanks! Chris
