Hello and welcome to TSF,

Run an online virus scan at TrendMicro
http://uk.trendmicro-europe.com/ent...call_launch.php. Just follow the instructions on the site to run the online scan. If any viruses/trojans are detected, try to delete or clean them in that site. You may use Panda ActiveScan also at
http://www.pandasoftware.com/products/activescan. Otherwise, make sure your antivirus program has the latest definitions and run a full system scan.
