Could Mcafee Quick Clean or an infection be deleting my document files?
I have a DELL XPS M1530 with Vista Ultimate on which I'm having trouble with files being deleted overnight. It seems to be limited to the Documents folder although the first time it also affected the Videos and Pictures folders.
Some of the folders are renamed e.g. 'My Settings' becomes MYSETT~1.SH! and files within it are deleted. It happens between 0100 and about 0400 GMT, coincidentally when McAfee Quick Clean was scheduled to run. This has happened 3 times now, restoring the files using Vista's Previous Versions process.
I have carried out a full virus scan using McAfee SecurityCenter and spyware scan using SpySweeper - both report back clean and both are up-to-date.
I have created a HijackThis log that doesn't appear to have anything odd in it but I'm not an expert. I have run ComboFIx.exe a few times because the log didn't generate and there was an error message that it couldn't find the file whitedir01 on one occasion. The log fom the last run doesn't appear suspicious to my untrained eye.
The only potential adware file I've found is CSAUIE1.OCX which I believe is a coupon printer kindly provided to me by Nescafe but that was after the original problem first happened and I don't think is linked to this.
I've searched, scanned, recovered files, deliberately avoided posting any logs but can't find anything that relates to this issue (not helped by having trouble getting a search of ".SH!" as a file extension to work as I want it to).
I'm getting pretty stuck now and have no idea whether I've had an infection, cured it or whether it will happen again overnight tonight when I restore the files.
Any help will be greatly appreciated. Thanks in advance
