I have been told that I have the w3i.iq5.fraud virus. What does it do? The problem was that no matter which key I press, I get a number and it is incremented in sequence from 0 to 9 and back again.
If antivirus software won't work, you can try this manual removal guide:http://blog.teesupport.com/how-to-remove-w3i-iq5-fraud-virus-completely-manual-removal-of-w3i-iq5-fraud/
Hope it helps.
