I'm using windows xp.
I've been having problems with my computer for a few weeks now. At one point, things started slowing down. I ended up scanning, was told to reboot and my computer wouldn't finish starting back up. It just looped over and over. Reformatted, all seemed well for awhile. I started out using avast, but everytime I opened up firefox it would give me a warning, telling me that my computer was trying to connect to a malicious site. This happened with other browsers also, I tried a few of them. note: back to using avast.
Now, whenever I search for something on google.. I get redirected to websites I've never visited before. Once in awhile, firefox will open with multiple unknown websites open. I get notified about different things trying to open up a malicious website, such as firefox.exe and svchost.exe. Those two are the most common, but there have been a few others. It tells me that it's been blocked, and happens again soon after. This is pretty frequent.
If my computer is left untouched and running for awhile, my sound no longer works. I have to reboot to get it working again.. Sometimes the windows theme will revert to classic. I have no problems with any of this while I'm not connected to the net, though.
I've scanned with avast and malwarebytes, once in awhile I'll find infected music files that I don't remember owning on another drive. I remove them, but it doesn't seem to fix anything. I scanned in safemode, found a few there and removed those also.. still nothing.
I'm really not quite sure what's going on. I'm pretty noob at computers, so any help would be awesome.
