i cannot log into windows because of a virus (im almost positive, when i try to login, it flashes a screen that says trojan found on my antivir program, then immediately logs me out.

i want to scan from dos startup, but cannot find how to do it with current vdefs. i tried norton, f prot, avg boot scanning there was something wrong with each.

avg- wouldnt scan ntfs
f prot- wont fit on one floppy, dont know how to split
norton- cant get vdefs on disk, unzipped


does anyone have a solution that will fit on floppy disks and works well?

thank you very much in adavance

Kevin

hello kevin well i got a few possible solutions for you in dealing with boot sector viruses.


1. if u somewhat a computer tech use another hard drive with os and av on it to scan your infected harddrive. that way no files will be overlooked even the boot sector.(easiest and reccommended)

2. if u dont have a second harddrive, u can try a neat ms-dos command that is called fixboot....what this does is remove old boot logs and replace with a new one..so if u got a boot virus fixboot will remove it and restore orginial boot. u need winxp cd or win98 startup cd that contains the commands.


3. last/worse case is formatting harddrive and fdisk it...... i have seen a few harddrives that required it as a worse case fix its usually the first thing computer techs do because they either dont know how to remove viruses/boot or dont want to waste trying figureing it out. i however only do it as a last possible solution.

i would strongly reccommend buying a cheap 2gb harddrive with os and antivirus software on it just for these cases..in the long run it will save u alot of time and money.

pap0007,

If you have a CD-drive that you can boot from, you can make an XP Boot CD with McAfee Antivirus on it. Download Bart's PE software and read the help files on how to enable the Antivirus option. A bootable version of XP will fit on an 80cm CD and requires aprox 150MB. The nice thing is its portable and costs maybee 25-cents for the disk.

It is possible to virus scan a XP NTFS from a DOS diskette with an up to date virus scan (I do it all the time) but you can not fix or remove a virus that is found, because you would not have write access.

I have a Windows ME boot diskette with the NTFSDOS.exe program added to it. Its image is used to make a bootable CD. On the CD I have copied the DOS rescue virus scan program and its definition files. After booting (and loading the NTFSDOS.exe to access the NTFS disks), the DOS based virus scan works quite well in scanning any drives. But if it finds a problem on a NTFS drive, there is nothing I can do about it because from DOS you do not have write access to the NTFS disk.

There are product$ that would work and give you write access from a DOS based program.

Have you tried booting into SAFE MODE instead? From Safe Mode you should be able to read and run a copy of McAfee's Stinger from a diskette. That at least would allow you to check for the most common virus, and to remove them. That might allow you to fix your AV program and then run it in Safe Mode.
