I have an oldish eMachines EL1600 with an Atom 230 1.6Ghz processor and 1Gb ddr2 dram running Win XP Home SP3. I hadn't used it for a while because it became very slow and would frequently freeze especially when connected to the internet but I now need to start using it again.
Installed anti-malware was Avast(free), SuperAntispyware(free), Malwarebytes(free), these have now been replaced with AVG Ultimate 2016.
I believe it may be infected with something and I need some assistance to clean/disinfect it. I've tried to do it myself, including trying to follow the BC slow PC/internet guides but to be honest my skills at such things are limited and my head is now in a spin.
Any assistance would be much appreciated.
I recently purchased AVG Ultimate, including AVG PC Tuneup, for an Acer laptop running Win Vista and hoped that the AVG PC Tuneup would help solve the issues with the eMachine. Well, it didn't, it made it worse. I contacted AVG who told me that the machine only had a 32gig processor which wasn't good enough for the AVG Ultimate and, via their remote access GoToAssist, told me that it was infected with Caphyon, a browser hijacker, and other malware.
AVG also told me that the installed programs CCleaner, SuperAntiSpyware(Free), Malwarebytes(Free) and remnants of Avast Antivirus(Free) plus other tools would interfere with the operation of their software and visa versa and effectively result in the PC not being protected at all. They offered to resolve these issues for 159.99 sterling (UK), which I can’t afford especially as I had just paid 59.99 sterling (UK) a week before it went down to 19.99 sterling (UK).
According to the AVG website the eMachine just about meets the minimum requirements for the AVG Ultimate. Their comment about the 32gig processor and offer to correct the issues of a PC that wasn't good enough ran alarm bells so I declined their resolution.
I found that by disabling some auto-start items, including PC TuneUp that I could get the PC to run stable enough to update the AVG antivirus and then disabling the AVG antivirus I could get the PC Tuneup to update, albeit with a lot of coaxing and several reboots. Then, using the PC Tuneup the PC became more responsive and stable and more still after using the PC TuneUp's Startup Manager option to switch off auto-start programs.
I scanned the PC with:
AVG which found nothing.
Hitman Pro which found and cleaned 11 items two of which were trojans (?).
ClamWin Portable which found nothing.
McAffee Stinger Portable which found nothing.
Kaspersky TDSS Killer Portable which found nothing.
I also ran HijackThis Portable which seems to suggest there are auto-start items that are disabled but Sysinternal's Autoruns shows at least some of these to be enabled, however, I don't really know how to interpret the HiJackThis results so I could be way off the mark.
Autoruns also shows there are a number of Avast items still loading despite the software being uninstalled.
Although the PC is just about usable it still very slow, has short & long term freeze ups and sometimes takes ages to refresh a screen especially when using the internet. These issues remain whether AVG and PC Tuneup are disabled or not; they are, however, worse when enabled especially when AVG updates.
Some of the slow internet problems are probably down to a slow WiFi connection.
