New virus worm which arrives as attachment see http://securityresponse.symantec.com/avcenter/venc/data/w32.novarg.a@mm.html

Just had look at internet setup and found that page had been changed to adware and power cleaner which was a page I was redirected to when I had reconnect to Internet before my problems started.

Might be useful to somebody for the future.

download.com for all free software from virus checker to firewall, would suggest
using mozilla instead of internet explorer, use AVG and SPYbot

Can anybody tell me what PowerScan.exe does?
