I am having trouble with my desktop, Window XP, SP3. It was first infected with AV security. I tried System Restore to one or two days ago. Didn't work that well, because at the same time, I have BSoD (0x7e). I could only entered safe mode if I pressed ESC to stop SPTD.sys (I do not have Daemon tools or alcohol). After I renamed sptd.sys and sptdxxx.sys, now I could start windows without BSoD.
I used Malwarebytes to scan the computer and removed a few infections. I also used SuperAntiApyware and SpyBot to scan the computer and did a few more cleaning. But even with all these, I still found a few problems
1. I cannot connect to windowsupdate.com (both firefox and IE)
2. I get redirected when I search on google (I tried to search for anti-virus scan); somehow the first time I clicked on one of those links, it seems ok, I got to the right website (for example, AVG). But when I went back and click again, it started to redirect me to other websites (for example, AVG was redirected to stopzilla).
3. when I connected to Pandasecurity and housecall.trendmicro.com, my firefox popped another tab "126.96.36.199 go.php" which I found very suspicious.
Oh, and earlier when I found this redirection problem persists, I used malwarebytes to scan it again. It found Trojan.Dropper. But when I tried to delete it, the computer froze and I had to reboot it. But after that, I scanned it with malwarebytes and found nothing (the log attached).
I also attached the log files from HijackThis (I just did another scan) and two others logs of Malware scan in the past two days.
Please help. I am this close to give up this desktop and thinking about re-install.
I would also like to add some information. Adobe reader was somehow invoked (by those websites perhaps) during these occurrences, even though I did not open any pdf files or download any pdf files at that time.
