XP Service Pack 2
I was infected recently with a number of viruses, adware, malware, etc. and managed to remove most of problems. But there are two files. tdsslog.dll and tdssserf.dll that I can't seem to get rid of. The scanner picks them up when I launch it and it's testing memory and start up. Attempting to delete them gives me the message that they are in memory and can't be removed/altered. I've tried running avast on startup and it says that the infected files are successfully removed but then they show up again when I run the scanner after startup and it's just an endless loop of all this. I've tried manually locating the files and they aren't there (show hidden files is on) and windows searches dont come up with anything either.
In addition to running Avast I've run Spybot Search and Destroy which got rid of the adware problems but it the exact same issue as Avast had with something called Virtumonde.sci I think. There were two registry entries that it could only remove before startup. Now it's random as to whether or not the program picks them up. Manually locating them didn't work, as if they didn't actually exist at all.
A couple of what I'm assuming are related problems: Clicking on any link in a Google/yahoo search sends me to various add sites instead of where I'm supposed to go. Copy and pasting the proper URL works on occasion. Most sites related to virus help including Avasts sends me to the "Cannot connect" page. My main browser is Firefox (one version behind the most recently released one), but Internet Explorer had the same problem as well.
A couple of other issues that didn't start until after infection: There have been three completely random system freezes; Sometimes on startup windows gets stuck right after the XP logo screen. Black background with a mouse cursor and I've left it there for an hour with not luck. It seems to work just fine every other time. I get the same result with Safe Mode, sometimes it works fine other times it gets stuck as soon as the screen with safe mode in each corner comes up.
Now, aside from the issues mentioned above, when its up and running my computer works just fine. There aren't any strange processes in the Task Manager, no abnormal CPU or memory usage, no system slow downs, no popups or desktop background images, programs (games, business, etc.) run fine. It's all very confusing.
If any of the issues i mentioned are unclear just ask me to clarify exactly what the problem im experiencing is. Thanks in advance for your help.
