Does Malwarebytes corupt Quickbooks Program?

[rivrbyte]

My sister has a dell desktop using WIN XP Pro.

She;s been having issues with her Dell. She got a message telling her to insert the WIN. XP install disc. I told here to go to F-12>Boot Options,and run a diagnostic. Her Samsung HDD had no bad sectors.

Now her scanner told her it can not find the TWAIN drivers. She could do a restore,but still has to run her Malware and McAfee program. She was told by Geek squad that McAfee is not the best anti virus software.

Basic Question here is...

Can Anti-virus and Malware programs mess up the registry and program files? She doesn't want to format and re-install the O.S. all the hardware and software again. She was also told that REGCURE is a good program, but I was told that a few of these registry utility tools give you a false sense of security and actually cause more problems that not.

A while back, I was slammed with ongoing multiple pop up ads telling me my Internet Explorer was corrupted, and would not go away, so I got fed up and did a format and reinstalled everything again, which is always a nightmare and a waste of time.

I would system restore to beforr the problems, then uninstall mcafee, regcure and any spyware programs. I would then download ccleaner and run it, and clean temp files. Then download combofix and run. After restart run mbam and insyall mse

certainly sounds like corrupt files, or something. Run a chkdsk? The Dell diagnostic utilities aren't exactly the greatest; I would honestly use something else.

Now her scanner told her it can not find the TWAIN drivers.

do a restore to a date prior to when the issues started. It's very possible something else caused some wonky things with the system. It's also possible it is a hdd issue; just not bad enough to error out the Dell diag utility.

My God, Geek Squad said something smart!?! lol
No, McAfee is certainly not the best. Microsoft Security Essentials and Avast are a couple of the best freebie AVs out there; and I'm pretty sure they both beat McAfee.

Basic Question here is...

Yes, it certainly is possible for an anti-maleware/spyware or anti-virus to have a false positive. In which case, the false-positive could get quarantined and the file would no longer be available for use.

She doesn't want to format and re-install the O.S. all the hardware and software again.

so try a system restore to a restore point prior to when the issues started occuring.

She was also told that REGCURE is a good program, but I was told that a few of these registry utility tools give you a false sense of security and actually cause more problems that not.

I don't trust 99.9% of those "registry cleaner" apps. CCleaner is all I use; and even then, it's only to remove the KB-update uninstallers from the add/remove programs list.

A while back, I was slammed with ongoing multiple pop up ads telling me my Internet Explorer was corrupted, and would not go away, so I got fed up and did a format and reinstalled everything again, which is always a nightmare and a waste of time.

again, a system restore can get things working. Depending on what is actually causing the issue, it may or may not come back.

Malwarebyte's heuristics engine "Shuriken" has been known to delete stuff it should not have.
I'd consult them on their forum.

I would run a ram checker like Memtest86+ to see if bad RAM is corrupting system files. This should be checked first, because if that's the problem, any other attempts to repair will also corrupt data.
