I am having a problem with an XP Home PC. This machine was infected with numerous malware, such as AntispywareXP 2009 as well as many others. I have run several removal tools, such as Spybot, SuperAntispyware, AVG, etc. Everything that has been found has been removed. The registry has been cleaned using HiJackThis. I cannot find any further traces of anything running on the machine. However I think some settings were not fixed after those malware were removed.
The main problem right now is that I cannot access some sites or open IE7. I can use Firefox, and can get to most websites with no problem. However if I try to access a site used for malware cleaning, like www.pctools.com or www.pandasecurity.com, the pages fail to load, even with Firefox. It seems to me whatever malware infected this machine, it prevented access to certain popular malware removal sites. Because of this, I cannot run updates to SpyDoctor or Norton to get current definitions, etc. As far as IE7 is concerned, if you try to open it, it tries to open for briefly but then disappears. This happens in Safe Mode w/ Networking as well.
When trying to ping these sites,for example www.pctools.com, for some reason it tries to ping the loopback adapter 127.0.0.1 instead of the IP address for the site. Yet if I ping www.yahoo.com it pings fine. If I try to ping the actual IP for www.pctools.com, it pings fine. So it seems like some kind of DNS issue or something?? This also happens in Safe Mode w/ Networking as well.
I have checked the HOSTS file, and there are no entries in there. I have checked TCPIP and Internet settings, nothing in there. I have reset winsock, reset TCPIP and Network Connections, checked trusted/untrusted Zones, and nothing has helped. Any other suggestions?
