System is Windows XP Professional sp3 with IE 7.0 installed and AVG Anti-virus (does not include a firewall). Computer was infected with various malware. Removed HD and attached to another system to run scan using Superantispyware. Scan completed successfully and removed several items. Re-installed HD in customers computer and ran Superantispyware again. Additional items were found and removed. After scan everything seems to be working normally except Internet Explorer.
