Yeah, I recently picked up a VERY bad malware program on my PC, too.
It masquerades as an anti-virus/anti-malware app but is actually malware, itself!
I think the name of this “app” is Live Security (something). AVOID IT if you can!
I’ve stopped this stuff from installing on my PC in the past but somehow it got past me and installed on my desktop.
Once it does that, it “requires you to pay” with a credit card to remove it! DON’T PAY – that’s the whole scam of the program…!
Unfortunately, I think it’s next-to-impossible to remove without reformatting the hard drive…
I tried several of the programs people talked about in this thread BUT they only made my situation worse. Before, Live Security would block operation of most MS and HP programs on my PC but after using those programs some critical components of Windows XP were potentially erased/corrupted so now I’m at the point that I’m going to have to restore the whole darn PC. I can’t log onto Windows without a forced reboot that sends the computer back to the DOS screen… it’s really annoying and there’s essentially nothing I can do now until I get a Recovery Disk in the mail…
Good thing companies exist that sell Restore Disks! The problem I have with the PC I own is that the manufacturer NEVER shipped it with an OS/Recovery Disk. To save some money, HP put the recovery program on a sector of the HD and required end-users to burn their own Recovery Disks. (Yet another example of companies being cheap! The other big thing they do is put software instruction manuals on PDF on CD-ROM. Now YOU have to print out several hundred pages for any app you want to have a reference manual for!)
Unfortunately, my dad, the former owner of this PC, NEVER read the manual and never made a Recovery Disk. In the meantime, that PC underwent several refurbs/purges until I got it after he retired. The machine had some minor issues when I inherited it and I doubt the Recovery app was still intact after all that action…
This crap has never happened on any of the PPC Macs I’ve owned (including the one I’m using to post now).
However, since Apple switched to Intel chips for CPU’s, there have been instances of MacIntels getting corrupted by malware, too.
