[QUOTE="analog, post: 287249, member: 29791"] In September, TwinHeadedEagle helped member Gene F. solve his dllhost spawing problem. I have an issue that appears to be the same persistent problem and possible infection of my system. I initially tried to start a private conversation with TwinHeadedEagle before I noticed his instruction to post issues in the forum rather than contacting him directly. Sorry about that. My computer is a Dell Latitude E5420 running the 64-bit version of Windows 7 Home Premium with Service Pack 1 installed. I use Norton 360 as primary security and also run SpyBot, Malwarebytes and CCleaner from time to time. The system has been stable and running clear for over a year up until last Friday or so when it started to bog down and well established websites began regularly to go unresponsive. The specific symptoms: Processor and memory usage at very high levels. Numerous and respawning dllhost.exe *32 Com Surrogate processes running. Norton Blocked messages: System Infected: Trojan.Powelik Activity Web Attack: Exploit Toolkit Website 33 Trojan.Adclicker Activity Other error messages: Norton High Memory Usage by COM Surrogate Windows message Powershell has stopped working. In addition, Inrernet Explorer security settings keep switching back to prevent downloads. I ran a Norton 360 full system scan and nothing was detected. I ran the Norton 360 registry clean up and some minor issues were resolved. The problem persisted so I ran SpyBot free edition. It detected and removed some tracking cookies. The problem persisted so I ran CCleaner. It did not detect any malware or the like, but it did cleanup files and it resolved additional minor registry issues. The problem persisted so I ran Malwarebytes Anti-Malware free edition. It found a few items and quarantined the problems. The problem persisted so I ran Norton PowerEraser. I cannot recall if any problems were detected, but it successfully ran to completion. Norton support tried removing backing out a Windows update that they believed was the problem but the problem reappeared after about an hour. I used the Norton firewall to prevent dllhost.exe from accessing the Internet, and that seems to have isolated but not fixed the underlying problem. It appears that I have some deep infection or other problem that the usual tools cannot remove or resolve. I have run the Farbar Recovery Scan Tool and the frst and addition txt files are attached. Thanks very much in advance for your assistance with this matter. Regards, Analog [/QUOTE]
