I am using Windows XP Home Edition SP3 on an Emachines T3624. All MS Critical updates and Avast! Definitions are installed.
When I return startups to Selective Startup after using Diagnostic Startup, Avast! 5.0.594 does not return to the selected status in the Startup list in msconfig. However, the Avast! 5.0.594 icon returns to the task bar with the red shield and “x” indicating that the application is disabled and selecting “Enable” from the Context menu /Avast!5.0.594 Shield Control does not work. In addition, selecting “avastUI” on the msconfig startup list does not help as after restarting the computer “avastUI” is again unselected and the “avast! Antivirus”, “avast! Mail Scanner”, “avast! Web Scanner” and “Remote Procedure Call (RPC)” Services are disabled. After setting the Remote Procedure Call (RPC) Service to Automatic/Started, still the Avast! Services cannot be enabled and I get an “Access Denied” error. The only solution is to perform a repair-install or complete reinstallation of Avast! 5.0.594. After this problem first occurred, twice, I was able to reproduce the exact same scenario.
@ rdmaloyjr, The OP stated that he already uninstalled/installed twice, so something else is going on. Asyn is correct in trying to find out what other security software the OP has as this may be conflicting with Avast.
Fastfood, we will await your reply to Asyn’s question regarding what other security software you have on your machine. This includes previous antivirus, firewall, and other security software that you are currently using. Thank you.
Thank you for responding. Sorry it took so long to post back. After first posting I went to bed. Then, this morning I found that my Firewall, Zone Alarm 7.0.483 which is the only other security software, even the XP Security Center is disabled, on my machine had some how become corrupted and would not repair or reinstall until I had gotten rid of all related files. Then I ran a boodtime full scan with Avast! which seem to take for ever and had reported three Trojans, all Win32:Trojan-gen in the Outlook Express Store folderwhich arrived as spam disguised as invoices from DHL delivery service. I recall them arriving and coping and sending the source code of the headers to DHL but I do not recall opening them, but perhaps I actually forewarded though I tend to purposely avoid opining spam. Do you think I should submit them to the virus lab?
