I know that most on this board are aware of this issue, but figured that I would share my experience in case it is helpful to anyone. I am relatively new to Prevx, but work in IT (mobile computing) and possess an advanced knowledge of computer hardware and software accordingly. Long story short, I have been building, configuring and using computers since the days of DOS and the lovely TRS-80. I bought an Acer X1300-U1801A and performed a clean install of Windows 7 Pro on August 16th (thank you MSDN). I am using the current release of Prevx (v220.127.116.11), but no other antivirus or anti-malware applications are being used. I do have the default Windows firewall enabled, but Windows Defender has been disabled. After installing Prevx, I initially left all settings at their default, with the exception of the following: 1) disabled the splash screen, 2) enabled enhanced rootkit detection, 3) set to automatically block access to infected files without prompting, 4) added a password, 5) set up a daily scan schedule. The installation was fast and uneventful. Within a short period of time, however, Google Chrome [v18.104.22.168] and IE8 [v8.0.7600.16385] started to crash and recover on a frequent basis. For the record, this had not been an issue before I installed Prevx. Here is the log entry from one IE8 event: Faulting application name: iexplore.exe, version: 8.0.7600.16385, time stamp: 0x4a5bc69e Faulting module name: WS2_32.dll, version: 6.1.7600.16385, time stamp: 0x4a5bdb4a Exception code: 0xc0000005 Fault offset: 0x000048c5 Faulting process id: 0x1500 Faulting application start time: 0x01ca868618b4eb50 Faulting application path: C:\Program Files\Internet Explorer\iexplore.exe Faulting module path: C:\Windows\system32\WS2_32.dll Here is the log entry from one Google Chrome event: Faulting application name: chrome.exe, version: 0.0.0.0, time stamp: 0x4b1ff63f Faulting module name: WS2_32.dll, version: 6.1.7600.16385, time stamp: 0x4a5bdb4a Exception code: 0xc0000005 Fault offset: 0x000048cb Faulting process id: 0x1194 Faulting application start time: 0x01ca84b55f2746c8 Faulting application path: C:\Users\Lyondellic\AppData\Local\Google\Chrome\Application\chrome.exe Faulting module path: C:\Windows\system32\WS2_32.dll I noticed that both events were related to WS2_32.dll and decided to lower the default SafeOnline setting for http:// sites. I also used the command "netsh Winsock reset" under Admin to reset and rebuild the Winsock catalog. After taking these actions, the issue manifested less often, but nonetheless persisted at an unacceptable frequency. After weighing my options, I decided to disable SafeOnline. To compensate, I increased Advanced Heuristics to Maximum and raised Program Popularity Heuristics to Medium. Since these changes were implemented, the issue has not manifested. Clearly, SafeOnline has some compatibility issues that Prevx needs to address ASAP. Until then, I intend to leave SafeOnline disabled. I welcome any suggestions or comments. I am the first to admit that everything I know about computers is due to me breaking something and the untold hours spent "unfixing" the damage.
