It could very well be malware.
Does bit set up temp files? If so, delete them.
After you're sure there's no malware remaining on your computer you need to install SP2 and then the other 8 critical updates that Microsoft made available this week.
I suggest yop do some web based scans:
online trojan scans here - http://scan.sygatetech.com/pretrojanscan.html http://windowsecurity.com/trojanscanWeb based online Antivirus and anti-malware scans:
(these can be run regardless of whatever else you are using. You must use Internet Explorer to run these.)
Kaspersky Anti-Virus Web Scannerhttp://www.kaspersky.com/service?chapter=161739400#betatest
Windows Security Trojanscanhttp://www.windowsecurity.com/trojanscan/trojanscan.asp
Panda Activescan (IE only)http://www.pandasoftware.com/activescan/co...n_principal.htm
Trend Micro antivirus and malware scan:http://housecall-beta.trendmicro.com/en/st...orp.asp?id=scan
Etrust Anti-virus web scannerhttp://www3.ca.com/securityadvisor/virusinfo/scan.aspx
I assume you have an Anti-Virus program updated and running.
