As I type (so far as I know) there's no current problem on my computer, but I'm concerned with something that's been happening to my internet/browser so I thought I'd post in case it 'kicks in' again and I can't get on here for help. (We're all connected through a D-Link DSL-G604T router - I'm the only one in the family that has had this problem though - I'm hard-wired, other computers are wifi).
A few weeks back my computer was running perfectly following a repair (except that I couldn't 'activate windows'). Then one day for no reason I can fathom, my internet browsers (IE8, Opera, Firefox 5 (now 6), Google Chrome) started to open more slowly and on certain sites (eg UK site of PC World of all things) my Opera browser would freeze and say 'not responding'. I couldn't close Opera (alt/control/delete, task manager etc - nothing worked). With IE8 on certain sites it appeared that there was a graphics issue in that if I scrolled down it would completely distort and it wouldn't clear. On both it seemed as if the full page wasn't loading properly. Firefox showed the page but functionality was affected in that I couldn't go onto the next page of a site. Google chrome also behaved weird and froze.
I ran checkdisk in case there was a file corruption & defragmented my disk with PerfectDisk 11 (which is done regularly anyway). No file errors found, no problems with the disk.
Must be a virus, trojan or worm I thought so I carried out full virus and malware scans (latest AVG free, Malwarebytes, IOBit Malware Fighter Pro) and various other free scans (eg Trend Micro & the free Kaspersky scanner) but they found nothing - tried Malwarebytes in safe mode too. System restore was a no go, 'last known best configuration' didn't help, the internet was unusable, and I then got locked out because I couldn't 'activate' windows.
So I carried out a full clean reinstall after reformatting the disk, and activated windows successfully. I've also now installed Acronis True Image Home 2011 and backed up the entire hard disk on a separate Seagate hard-drive (my data is regularly backed anyway) and I have 2 reboot disks just in case (the original Acronis CD and a further one made via the Acronis program).
Worryingly, last night, a week after the clean install, exactly the same thing happened - again nothing found on any scan. This time, I could restore back to 26 August 2011, and all is well again. But I'm worried that this has happened again and if I can't restore or there's a problem with Acronis (it's highly recommended but I've learned that nothing is 100% guaranteed when you're talking computers) I'm back to a full clean install again which is time consuming to say the least (not least because my Windows XP Pro disk was damaged & I had to use my old Mesh XP Home disk that wasn't even SP1 - so I had to put on SP2 before I could update all the drivers, then SP3, then reinstall printer, Office XP etc etc!)
Sorry this is all a bit long winded but I've tried to give as much info as I can think off. I was therefore just wondering/hoping if any of you guru's out there had any clue as to what's going on with my internet/computer?
UPDATE - just happened again this morning. Only thing I'd done is put Obit malwarefighter back on my computer. Maybe there's a conflict? Anyway, restored to 26 Aug again & this time I've not reinstalled Iobit malwarefighter. I also ran RKill and fully scanned with AVG/MalwareBytes & again nothing found - so I'm hoping its not an infection. Fingers crossed.
