Hello and thanks in advance for any help you're able to provide. I'm operating a home PC in England, using XP Home protected with Zone alarm, Grisoft AVG and Adaware. All's been fine for years until recently, when while browsing I suddenly gained a new toolbar. Since then, over a period of approx 5 weeks, I've been grappling with a computer which hasn't been behaving properly. Using advice gleaned from here and similar helpful sites I've managed to clear everything malicious from my system that can be identified by the following programs:
Adaware; CCleaner; Ewido; Avast Virus Cleaner Tool; Spybot; Stinger2; CWShredder and Kill2Me, plus the Bit Defender and Panda online scans.

Having gone through all of the above (in varying orders and repeatedly) I was left with 2 problems which wouldn't be fixed:
a) Ewido reported 2 Trojan.DNSChangers in my registry, which subsequently I killed using Alcanshorty and Fixwareout
b) An entry for Wurldmedia and Pipas .exe files reported and killed by Spybot but which recur quite frequently and therefore may not be as dead as I'd like to believe.

So apart from (b), above, all these cleaners report me as 'clean': but something's still wrong, as I'm still not achieving problem-free browsing: almost, but not quite. Every now and then I'm being re- or mis-directed to a blank or unwanted webpage - not to any disturbing extent, but still evidence that things aren't quite right.

I've cross-checked my own Hijack Log against Google as best I can, but if anyone could glance at the attached I would be very grateful. There are a few items on the list that I'm suspicious of.

Thanks
