If I use Google CHROME on my Dell Inspiron 17R runnning Win 8.1 the daily Malware AntiMalware scan reports on two "PUP.Optional.Conduit.A" instances: " Malwarebytes Anti-Malwarewww.malwarebytes.org Scan Date: 4/21/2014Scan Time: 9:13:56 AMLogfile: Administrator: Yes Version: 2.00.1.1004Malware Database: v2014.04.21.03Rootkit Database: v2014.03.27.01License: PremiumMalware Protection: EnabledMalicious Website Protection: EnabledChameleon: Disabled OS: Windows 8.1CPU: x64File System: NTFSUser: chuck3 Scan Type: Threat ScanResult: CompletedObjects Scanned: 307489Time Elapsed: 5 hr, 11 min, 55 sec Memory: EnabledStartup: EnabledFilesystem: EnabledArchives: EnabledRootkits: DisabledShuriken: EnabledPUP: WarnPUM: Enabled Processes: 0(No malicious items detected) Modules: 0(No malicious items detected) Registry Keys: 0(No malicious items detected) Registry Values: 0(No malicious items detected) Registry Data: 0(No malicious items detected) Folders: 0(No malicious items detected) Files: 2PUP.Optional.Conduit.A, C:\Users\chuck3\AppData\Local\Google\Chrome\User Data\Default\Preferences, Good: (), Bad: ( "homepage": "http://search.conduit.com/?gd=&ctid=CT3321972&octid=EB_ORIGINAL_CTID&ISID=ISID_ID&SearchSource=55&CUI=&UM=5&UP=SP7F6038CF-2DE8-4DB4-A8BA-CBD031EBFB48&SSPV=",), Replaced,[a94ede4e42391125393b70e5788cd42c]PUP.Optional.Conduit.A, C:\Users\chuck3\AppData\Local\Google\Chrome\User Data\Default\Preferences, Good: (), Bad: ( "startup_urls": [ "http://search.conduit.com/?gd=&ctid=CT3321972&octid=EB_ORIGINAL_CTID&ISID=ISID_ID&SearchSource=55&CUI=&UM=5&UP=SP7F6038CF-2DE8-4DB4-A8BA-CBD031EBFB48&SSPV=" ],), Replaced,[e017ef3d7a0166d0089efb5a39cbe61a] Physical Sectors: 0(No malicious items detected) (end)"Are these real malware? I realise that Conduit is known malware but if I have it, it must be hiding very well. I quarantine them every time they show up, but if I use Google Chrome again they recur. Does anyone know how I can clear these permanently?
