Please help! I have a virus of some sort that is acting particularly nasty. First, it removed all system restore points, except right after I got infected. It also has spawned several other .exes, like a.exe and msa.exe, each of which I have killed, but they don't seem to be acting like a typical a.exe or msa.exe infection. It has also hijacked all of my google searches. I can do a search, but clicking a result link sends me to a seemingly random site or alternate search result. And lastly, and most frustating is that Norton didn't find it, but still run and Spybot, Malware bytes, and even HJT will not run giving a "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access this file." whether I run it from the shortcut or the file directly. I have verified that I am in the administrator group and even logged in as administrator, or in safe mode as administrator, the same thin happens. This is an XP box running SP3, IE8 , and up to date security. Like I said, I have tried to run everything I can and don't know what to do next, please help!
