The inability to login to a site does not indicate a virus.

Are you running an anti virus software package?

Is it's DAT files up to date?

Have you checked your system for suspect processes and files?

If not do so and upload them to www.virustotal.com

also give this a shot:

Anything beyond that requires me to believe you will have a level of technical knowledge that is not sufficient to understand what needs to be done. I am not trying t be a dick or anything, but I do this for a living and I spent the last 6 years hammering my skills to be able to detect new viruses so that I can use my knowledge and instinct to find threats that current virus scanning tools with current DATs can not detect.

Frankly - there is no way I can impart that knowledge here in this little white text box.

I do not work for McAfee or any other vendor - I have simply spent several years doing product analysis and comparisons with captured known viruses and worms including encrypted self modifying worms that are nearly impossible to defeat. All I can recommend is simple to use software packages that have a proven track record of success and some of the best R%26D in the world.

If you have nothing - I would recommend spending the money to by McAfee - while it isn't perfect it is stable and 99.9% reliable in detecting new threats in a reasonable amount of time. Just remember all anti-virus tools are re-active tools and can only work on historical data.

I would also recommend getting Site Advisor - it is free and is now owned by McAfee. www.siteadvisor.com

This little tools tells you a web site has potentially harmful software that can harm your computer before you even visit it.
