Hi! I have a mildly concerning problem. It seems something is wrong with *.exe on my computer. Let me try to expand on this. When I try to run a program I get the error message: *(Program Name)* caused a error <Unknown> The program has been shut down. This is a rough translation, as I am using Polish Win. ME. Anyway this happenes for every program I try to run, be it Windows programs like System Restore, or downloaded programs like DIVX player, but the funny thing is, that sometimes I get them to open, like for example my internet program which is also a exe and it allows me to connect to the internet. Im not sure, but I think that if I turn my Internet program off, I may have trouble again to turn it on again. I have Norton 2002 installed and up to date, and last night apon getting the first of these <unknown> error messages (i was opening mplayer2) I ran a system scan. It came out that I had 10 files infected with Trojan.ByteVerify. I followed the steps of removal that are on the symantec website: Turn system restore off, run in Safe mode, delete all files containing the virus. After doing this most programs (including Norton, my internet, etc. did not want to turn on at all, and I got the same <unknown> error. Today I turned my comp on, restarted it a few times and after like the 7th restart I got my internet working, my Nero (so i burned all my docs) and my Norton, which says my system is clean. This is strange, because I closed Nero, and then opened it again, and closed it without problems, but still other programs give me <unknown>... I know this is a rather complex problem, but I dont know (other than defrag my disk, which i would rather not do) what else to do! Also I dont have a firewall. Any suggestions? Thanks!
