I have seen very similar instances of this problem in the forum (http://www.bleepingcomputer.com/forums/topic360449.html/page__p__2016937__fromsearch__1#entry2016937
) and I have tried the solutions provided, but to no avail. About a month ago I got a handful of very painful viruses and malware on my XP computer. I have AVG installed and updated, along with a few other programs I run on demand occasionally, but apparently that was not enough. I have been able to knock out nearly all of the problems except I still have a few ghosts causing problems here and there. For one, I get the "Generic Host Process for Win32..." a couple of minutes after my computer boots up. Second, I cannot update using Microsoft’s software update web site. Third, I occasionally get random Internet Explorer windows popping up telling me I won a $1000 gift card to Walmart or that I need to download their AV software or something based on one of my recent searches. Forth, I still occasionally get my searches hijacked. And finally, every time I reboot I get errors that HPProductAssistant can't find the program and when it tries to reinstall it fails several times before it finally quits. I have installed and ran (repeatedly), Malwarebytes, SuperAntiSpyware, AVG, Windows Defender, SpybotSearchand Destroy, Kaspersky Virus Removal Tool, HijackThis, TDSSkiller, and a few others I am forgetting plus some online scans. When I was first infected I could not even get online and some files were deleted. With the help of online forums and the aforementioned programs, I have come a long way, but I cannot seem to get rid of these last couple of problems. All of the programs I mentioned now tell me I am clean except the TDSSkiller, which tells me I have a root kit and it quarantines it. If I go a day or so without manually scanning, some of the other programs will find something minor, but not the real source of the problems I am still having.
I apologize for being long winded. I just wanted to post as much info as possible right up front. Thank you in advance for any suggestions.
