There is not enough memory or disk space to run word

One day, seemingly at random (I know that it obviously was not), my steam client stopped working, so doing a virus scan malwarebytes returned a positive. So I removed it, but having done this I thought my computer was fine, but when I opened Word 2010 I got the error "There is not enough memory or disk space to run Word" I have 281 Gb of free hard drive space and 8 Gb of RAM. I even used the installation CD and used "repair" which didn't work. I also tried clearing the Temp folder, but the problem persists

It's possible that the malware you discovered damaged Word and/or other system files. Since you have an installation disk (which I'm guessing is Microsoft Office 2010), I would uninstall the entire suite.

How to uninstall or remove Microsoft Office 2010 suites

After uninstalling Microsoft Office I would check for damaged or corrupt system files by running a system file checker scan from an elevated command prompt (option two.) If problems are found, run the scan 3 times and reboot the computer after each scan.

SFC /SCANNOW Command - System File Checker

Since you know the computer was previously infected, it's very possible that other malware is still lurking. No anti-malware product is 100% effective 100% of the time. If there was such a thing we'd all be using it. Besides running Malwarebytes again, run some additional free on-demand scanners. My first choice is Windows Defender Offline. It's a bootable media which means it has to be made on a machine that is without malware. And some other free scanners.

WDO

ESET Online Scanner

TDSSKiller

Trend Micro HouseCall

SuperAntispyware

If all of the scans come back with no threats detected, I would next do some general hard drive housekeeping.

Disk Cleanup - Open and Use

Disk Defragmenter - Open and Use

Hibernate - Enable or Disable (If you don't use hibernate)

Once all of this is done, reinstall Microsoft Office. Please post back if you're still having "not enough memory or disk space" issues.

When I posted I had already: Scanned with Superantispyware(returned nothing),ran SFC/Scannow(returned no errors),Defragmented the hard drive(minor fragmentation), ran disk cleanup(10mbs to clean),ran a windows disk check(returned some errors, but didn't fix the problem), ran windows memory diagnostic(no errors), and cleared my Ubuntu partitions. I'm uninstalling and re-installing now, I'll post back with the results
