upon the advice of a friend, i downloaded the avast 4.1 home addition program. I had been experiencing problems with my computer for sometime and he swears by this program.
However after installing this program and running it it found a trojan. I deleted it all and wait for it to do it thing. when I returned to my computer it was back at the the logon screen (i run windows xp). I logged on to my name and itwould not let me open any programs. it froze. i can only run anything in safe mode any ideas?? I cannot even delete the program. I also have norton.
Use the Control Panel > Install/Uninstall Applications applet to remove Norton Antivirus (NAV) (it´s not necessary to remove other applications from the Norton SystemWorks not even LiveUpdate or LiveRegistration).
Boot.
Use RNAV2003 or this link to download and then remove traces of NAV into your registry. Download and run the application. If you have already done the first step, choose ‘No’ to continue.
Boot.
Do not remove manually or using another software the Registry keys, it´s not necessary (by now) and may be dangerous. But, if you want and do not fell unconfortable walking through windows registry and deleating the many left behind entries, there is some good registry cleaners available to aid in complete removal of these. Reg Cleaner is a good one but it is a Shareware (you can run once to do its job). Another links and applications could be found here at the section Registry Tools. For Windows 98, I recommend RegClean.
If you have time, you can read more at this Windows Registry Guide.
Install avast! (answer ‘Yes’ for the presence of another av, in this case traces of NAV). Starting with version 4.0.172, there is a functionality in avast! Setup to detect and warn the presence of Norton Antivirus installed on the target machine.
Boot.
You will have to change Registry “corrupted” keys by NAV, see here.
At last (after the boot), make a eicar.com test (see links here).
