My brother recently acquired a Dell computer. However, his friend came over and installed some cheating device for Runescape and the computer has been acting up ever since. Zone Alarm and AVG kept disabling and failing validation tests and spybot, ad-aware, spyware blaster were all starting to fail. I tried running them, but I had to resort to a format. I tried formatting, and the problem persisted. I have now tried formatting 3 times, both quick and full, upgraded to windows xp professional, installed all the spyware and adware and firewall programs, ran close to 30 scans, and still no improvement. At one point, it did detect Alexa, but this threat seems to have disappeared. I am now suffering from random shutdown, and Zone Alarm is unable to start due to "validation" issues. Avg also shutdown with the message, "The AVG program had a bad file". Doesn't sound very professional yet very suspicious. Whatever the problem is, it knows how to disable its enemies, hence the spyware and firewall, and it's able to withstand a format of the WHOLE computer. Please help.
Any suggestions would be greatly appreciated. I'm all out of ideas . Just a 16 year old kid trying to do his brother a favor.
Thanks in advance
Ps: Forgot to mention, lots of blue screens and random restarts.
Thanks for the help. I tried installing NOD32 and SpySweeper, but after that, XP couldn't load and kept restarting. So I tried DBAN, another forum member recommended it, but all that was give me errors but it did succesfully wipe my drive,whether or not it actually completely wiped the drive I don't know. So I went to the recovery console, and sure enough, c:\windows was missing, so I typed fixmbr, it worked, and I'm currently re-formating (full, not quick) the drive for re-installation of XP. Should this do the trick? Any other advice?
Once more, thanks for the help. I never would of thought to fix the Master Boot Record.
