On the McAfee forums, we're seeing such issues as the result of malware infections.. So, first, try downloading the manual DAT installer from the link below and run it to manually update Vs 8.7i. Download the full "sdat" installer which will update both the scan engine and the virus definitions at the same time. (If it's the first time at the site, you may have to click on the "I Agree" button, then downlolad the "sdatxxxx.exe" file for that day.)
If you're still having issues, please follow the instructions below:
Download ALL of the tools below on a friend or family member's, CLEAN computer and copy them to a CD or flash drive, then transfer them to the problem machine.
First, after transferring it to the problem machine, run the following tool to help allow the removal programs below to run. (courtesy of Grinler at BleepingComputer.com)
There are 4 different versions. If one of them won't run then try to run the other one. Be patient.... as a black window should open, then close after finding all the background programs.
Vista and Win7 users need to right click and choose Run as Admin
You only need to get one of them to run, not all of them.
IMMEDIATELY after running the "Rkill" tool above, run/install the Malwarebytes and SuperAntispyware installer and update files from the links below which you've also copied to a CD or flash drive, and transfered to the problem machine. Do NOT restart the computer after running Rkill.
Once downloaded and before transferring Malwarebytes and SuperAntispyware to the problem machine, rename the program installer "mbam-setup.exe" file to something else like "Gogetum.exe", then copy the installer file and the update file to a CD or flash drive.. Transfer the file to the problem machine, then install the "Gogetum.exe" file, then run the update to get the program current.. After that, run a full system scan and delete anything it finds.
Malwarebytes Installer Download Link (Clicking on the links below will immediately start the download dialogue window.)
Malwarebytes Manual Updater link
Next, install and run a full system scan with the SuperAntispyware program and the manual updater from the links below. As before, you may need to rename the installer file to get the program to install.:
SuperAntispyware Manual Updater
In a few situations, in order for the program to run, it was also necessary to rename the main "mbam.exe" file also after installing it.. It resides in the C:\Programs Files\Malwarebytes Antimalware folder....
Hope this helps.......
I work on an EEEPC, have McAfee 8.7i, Spyware Doctor and Comodo Firewall installed.
I have a habit of scanning every single file I download. Lately, though, my virus scanner doesn't want to scan any file I download. There's an error message popping up that says the scan can't be done because of a missing or corrupted DAT file and that I have to reinstall the product. It started around last night, and it's been like that for every single file I downloaded after - and I downloaded these files from the usual places I download from (torrent and zip). I tried doing a general scan but failed because the same error message popped up.
If it's related, my on-access scanner starts as Disabled during startup even if it's not supposed to be. I put the scanner on Enable and rebooted twice, to no effect.
What happened? Do I have to reinstall like the error message says? Thanks in advance.
