I have run the updated ewido again and again, and unfortunately the CWS still there. This is what ewido said: Registry: HKLM\SOFTW..\Classes\CLSID\{D2B24D87-699F-16C6-2875-242... Infection: Adware.CoolWebSearch Threat: High I clicked the button in ewido to remove it but nothing happened. Until finishing the scan, the list in ewido still was Infected objects: 6 Cleaned infections: 0 Ignored infections: 0 (note: only one CWS, the rest are TrackingCookie) Moreover, when finished scan, the Save report and View report buttons remain grey and after a second ewido closed automatically. I just could't read any report and cannot send any report here.....Do you think the CWS made ewido not work properly?
