I believe you DO have a trojan or virus. One of the key symptoms is contaminating your IE hosts file by entering virtually every AV site into host blocked url list.
Given that, first try going to the following site (if you can) and downloading Stinger. exe. If you can't get access can you have a friend dwnload to a floppy or even E-mail the dnloaded file exe to you?? Its is a stand alone special for a few current items and can be run right from floppy or desktop.:Stinger:
Meantime go to your IE Options>Security tab>Restricted Sites & click "sites". Look there to see if any Major AV sites are listed. If they are, you could manually delete some good sites to allow you access to those sites. Hopefully this will allow you onto the web to get further help from (likely) an Anti-trojan program you can download free trial of , update & run. You may be able to do housecalls online scan at this point if you've deleted TrendMicro(housecalls) & Vil. Nai.com(Stinger).
You will have to disable System Restore since its VERY likely its points are contaminated and will re-infect if used.
Many links to above in this link post to scumware revised:
I'm probably 1st to reply but others will come in soon. Meanwhile hopefully this will give you a headstart. Please report back. Carefully note the exact full name & exact full location of anything found.
I suspect your AVG has been corrupted so you may have to delete/ re-install once clean as several like this prevent install of AV/Spyware programs.
I have XP, run AVG and the definitions are up to date.
I even did a manual scan with AVG and it came up clean.
I tried to access many virus info site today and the response came up with "Page cannot be found"
I wanted to do an online scan which I like to do every so often for peace of mind. I could not accomplish this.
I did however manage to access MANY other websites that were not virus info related.
Not sure if this other problem is connected but a couple weeks ago I had a window come up whenever i started up my computer...."windows cannot find c:\windows\system32\irajakv\csrss.exe" make sure you typed the name correctly then try again. To search for a file click Start, search....
I then click ok (the only option) and another window pops up saying "could not load or run specified in registry. Make sure the file is on your computer or remove the reference to it iin the registry."
I click on ok (the only option) and then it repeats the messages again. I click ok and then I can continue onto whatever i wanted to do.
Also about the same time (couple weeks ago) I keep getting junk mail in my OE. I never got any junk mail before this and all i keep doing is block sender.
Anyone who has advise on this would be GREATLY appreciated.
Thank you in advance.
